1-1 Chapter 1 Introduction Compaq Integrated Remote Console (IRC) is an integrated hardware function that provides remote access and remote control to diagnose server failures interactively. IRC gives authorized users direct access to the managed server, independent of the operating system or other software, from locations a few feet away or from another continent.
1-2 Introduction ■ View a log of Integrated Remote Console events ■ Allow users without supervisory access to modify their login passwords Allow supervisory users to control access by other users ■ Remotely change the configuration parameters of Integrated Remote Console Benefits of Using Integrated Remote Console IRC advantages include: ■ Integrated, low-cost, hardware-based out-of-band management ■ Support for most standard, high-speed modems ■ Independent of the server operating system ■ Fu
1-3 Installation Sequence Outline In preparation for using IRC, the following tasks must be performed: ■ Prepare the management console with the necessary hardware and software for out-of-band communication ■ Prepare the managed server for out-of-band communications by installing a modem or connecting the managed server to a suitable communications device ■ Configure the usage and communication parameters of IRC ■ Set up a list of authorized users and their permissions in the IRC user database figu
1-4 Introduction Terminology Table 1-1 lists the standard terms used throughout this guide. Table 1-1 IRC Terminology Term Definition Managed Server Server that contains IRC or server which can be remotely managed through a variety of Compaq tools. Management Console Computer that runs management applications or collects management data. Management Application Software running on the management console that collects management data and/or provides access to the managed server.
1-5 Accessing Integrated Remote Console Integrated Remote Console can be accessed through either Compaq Insight Manager or through any communications package that supports ANSI terminal emulation. It can be accessed through Compaq Insight Manager by configuring the modem remote console feature associated with the managed server. When accessed through Insight Manager, Integrated Remote Console supports dynamic text mode changes and extended keyboard functionality, including the function and alternate keys.
2-1 Chapter 2 Setup and Configuration This chapter describes the steps required to implement Integrated Remote Console (IRC) using an internal modem, external modem, or direct serial port connection. See Chapter 6 for information on supported modems and for additional information pertaining to the appropriate configuration of modems with IRC. To operate IRC by modem, the management console must be equipped with a modem that is compatible with the modem in the managed server.
2-2 Setup and Configuration Configuring the Modem Configuring a non “plug-n-play” ISA Modem The Compaq System Configuration Utility does not automatically detect non plug-n-play ISA devices. Therefore, you must manually account for system resources used by an installed ISA modem. To configure the modem: 1. Boot the server and run the Compaq System Configuration Utility. This utility can be run from floppies or by booting the Compaq SmartStart and Support Software CD included with your server.
2-3 6. Select !ISA0010.CFG Generic Modem (for use with IRC) from the list of boards that appears. Figure 2-1. Example: Selecting a configuration file 7. Select the slot where the modem is installed when the Configuration Utility identifies appropriate slots for the modem, then press Enter. 8. Press F10 to return to the System Configuration Main Menu. 9. Select Step 3: View or Edit Details.
2-4 Setup and Configuration 10. Set the COM and IRQ IRQ resources to match the jumper settings on the modem. Note these settings as they are needed when configuring Integrated Remote Console. Figure 2-2. Example: Setting the COM and IRQ resources Configuring an external modem or direct connection If you are using an external modem or want to connect IRC directly to another computer, terminal, or terminal server, you must first configure one of the integrated serial ports on the managed server. 1.
2-5 4. Note the COM and interrupt settings for the desired integrated serial port; these are needed when configuring IRC. Figure 2-3. Example: Configuring an integrated serial port Figure 2-4. Example: Viewing the resources of an integrated serial port Compaq Integrated Remote Console User Guide Writer: Caroline Juszczak Project: Compaq Integrated Remote Console User Guide Comments: 281862-00x File Name: C-CH02.
2-6 Setup and Configuration Configuring Integrated Remote Console Use the System Configuration Utility to configure IRC. Table 2-1 summarizes the System Configuration Utility configuration options and their default values.
2-7 Integrated Remote Console Configuration Summary Continued Parameter Configuration Value (default settings in bold) Modem Settings (not required for direct connection) Initialization String (primary) ATZ Initialization String (secondary) AT&C1&D2 Dial Prefix ATDT Answer String ATS0=1 Security Access Supervisor Yes/no Remote Console Yes/no Reboot Server Yes/no Replay Boot Sequence Yes/no Force Dial-back Yes/no 1.
2-8 Setup and Configuration 2. Set the Keyboard type to match the layout of the keyboard on the managed server. For proper remote keyboard operation, this setting must match the keyboard country configuration of the server’s operating system. 3. Set Communications Device according to your hardware configuration: a. Internal Modem b. External Modem or c. Direct Connect if connecting with a null modem serial cable to another computer, terminal, or terminal server. 4.
2-9 Modem Strings Configure the Modem Command Strings (not required for direct connect): 1. Set the Primary and Secondary Initialization strings. These command strings are used to initialize the modem used by IRC. The Primary Initialization string must include the appropriate AT command to reset the modem to a known state. Since AT command strings can contain multiple configuration and command sub-strings, this string can also contain additional configuration commands.
2-10 Setup and Configuration ■ Modem result code options Chapter 6 explains modem command strings in more detail. Chapter 8 provides additional information on using the modem in shared mode. Appendix A contains suggested entries for proper initialization strings for several common modems. 2. Set Dial Prefix to either ATDT (tone - default) or ATDP (pulse) dialing. 3. The Answer String should contain the command string necessary to place the modem in “auto-answer” mode.
2-11 User Configuration You must have at least one user configured in the database to access IRC. The maximum number of users is eight. Use the System Configuration Utility to add, delete, or modify user entries. Users can also be added, deleted, or modified online from the IRC Main Menu if the connected user has supervisor privileges. To edit user information: 1. Select View or edit details from the System Configuration Utility. 2. Highlight Configure Users, then press Enter. Figure 2-7.
2-12 Setup and Configuration 4. Edit the following user information: a. User Name — Case-sensitive name that must be used when logging into the Integrated Remote Console. User names can be up to 11 characters in length. b. Password — Case-sensitive password that the user must use when logging into IRC. It must contain at least four characters and no more than 15. When setting passwords, the administrator is prompted for verification. c.
2-13 5. Verify/Change the user’s security settings. Position the highlight to Security Access and press Enter. Ensure the correct setting of the following security attributes: Figure 2-8. Example: Edit User screen a. Supervisor Rights — A user with supervisor rights can remotely modify all Integrated Remote Console configuration parameters, including the addition, deletion, and modification of other users. The default setting is disabled. b.
2-14 Setup and Configuration e. Force Dial-back — Integrated Remote Console logs out the user after successful authentication and calls the user back at the number specified in the Dial Back Number entry of the user’s data structure. This prevents the user from logging in from an arbitrary location. Figure 2-9. Example: Setting Security Access 6. Press F10 until you return to the User Maintenance screen. Repeat steps 1-6 for additional users.
3-1 Chapter 3 Establishing a Connection You can establish a connection to Integrated Remote Console (IRC) from any ANSI X3.64 compatible terminal or terminal emulator. This section contains specific information on how to establish a connection using either Compaq Insight Manager or Windows HyperTerminal. In addition, this section contains general guidelines necessary if an administrator wants to use a different terminal emulator application.
3-2 Establishing a Connection Configuring Insight Manager for Out-of-Band Remote Console Access To contact the IRC function of a server, there must be an entry for that server in the Insight Manager device list. If an entry already exists for this server, proceed to step #2. 1. If the server containing Integrated Remote Console is available for inband management through a LAN connection, create an IPX or IP entry for the server using methods described in the Compaq Insight Manager User’s Guide.
3-3 Figure 3-1. Device Setup window 4. Enter the phone number of the managed server in the Modem Remote Console configuration group. 5. Verify the COM port settings to ensure they are correct and reflect the configuration of the modem in the management console. NOTE: The COM port used for this configuration setting is based entirely upon the hardware setup of the management console and is not related in any way to the COM port setup of IRC. 6. Click OK to complete the configuration.
3-4 Establishing a Connection Establishing an Out-of-Band Remote Console Connection Right-click the managed server in the device list to display a list of menu items, as shown in Figure 3-2. Figure 3-2. Establishing a connection using Compaq Insight Manager If the server is configured for out-of-band remote console access, the Remote Console menu option is available. Select this menu item to initiate a remote console, out-of-band session with the managed server.
3-5 Insight Manager launches a terminal window and dials the number configured above. The call progress is displayed in the terminal window’s status bar. If configured correctly, IRC on the managed server answers the call. If the server does not answer (possibly indicating that the OS currently owns the modem), wait 60 seconds and try again. For more troubleshooting information, see Appendix C.
3-6 Establishing a Connection In addition to enhanced keyboard support, Insight Manager also offers enhanced display support. If the server console changes to a different display mode, this change is automatically updated in the Insight Manager terminal window. This is particularly useful when managing a Microsoft NT server, which changes from 25-line to 50-line text modes during the OS load process.
3-7 Figure 3-3. COM port settings 3. The COM port settings dialog box is displayed. The modem initialization string for out-of-band access on the management console is listed in the Modem Control Strings control group. The default value is “AT&F&C1&D2E0S0=0”. Additional configuration settings may need to be appended to this string (for example, some modems may require appending an &B1 (set computer-to-modem speed to fixed) resulting in a string like “AT&F&C1&D2E0S0=0&B1”).
3-8 Establishing a Connection Establishing a Connection Using Windows HyperTerminal HyperTerminal is a terminal emulation application generally available on any Windows-based management console. Since it supports ANSI terminal emulation and is a standard part of Microsoft Windows 95 and Windows NT, it serves as a good example of how an administrator could manage an Integrated Remote Console-based server from a standard ANSI terminal.
3-9 ■ No auto-answer support — Must manually enter modem commands in the terminal window to take advantage of call back. IMPORTANT: Make sure your IRC firmware revision revision is 1.41 or greater if you wish to use HyperTerminal to connect to IRC. In certain circumstances, HyperTerminal may not accurately transmit characters until is has received characters from the remote system.
3-10 Establishing a Connection Setting up a Connection To access IRC from within HyperTerminal, you must first create a “connection file.” This file contains the phone number and session-specific settings, which can be used for future connections. To create a connection file: 1. Select New Connection from the File menu. The initial dialog box, shown in Figure 3-4, prompts you for a name for the connection file. Figure 3-4.
3-11 2. Enter a name that describes the managed server, then click OK. 3. Enter the server phone number. Also verify that the modem identified under “Connect using:” correctly describes the modem in the management console, then click OK. Figure 3-5. Entering connection details HyperTerminal is now ready to dial into the managed server. Compaq Integrated Remote Console User Guide Writer: Caroline Juszczak Project: Compaq Integrated Remote Console User Guide Comments: 281862-00x File Name: D-CH03.
3-12 Establishing a Connection 4. Verify that HyperTerminal has the correct phone number, complete with any prefix codes that may be required to access outside lines or long distance services. Use Modify… and Dialing Properties… to make any corrections. Figure 3-6. Connection window Writer: Caroline Juszczak Project: Compaq Integrated Remote Console User Guide Comments: 281862-00x File Name: D-CH03.
3-13 5. After verifying the phone number, click Dial. You should be prompted with a status dialog box and hear the modem establishing connection with the managed server. Figure 3-7. Establish a connection using HyperTerminal The HyperTerminal application should indicate that a call is in progress. If configured correctly, IRC answers the call. If the server does not answer answer (possibly indicating that the OS currently owns the modem), wait 60 seconds and try again.
3-14 Establishing a Connection Invoke Integrated Remote Console Login After HyperTerminal establishes a connection, press Enter three times. This indicates that the incoming call is intended for Integrated Remote Console. IMPORTANT: After connection has been established, you have 10 seconds to press Enter three times to validate the call.
3-15 Establishing a Connection Using an ANSI Compatible Terminal Emulator The ANSI terminal standard allows access to IRC from most standard terminal emulation applications. Configuration Guidelines The following are general guidelines for using ANSI terminal emulation programs to access Remote Console. Display Settings Display font — If the display font of your terminal application can be configured, choose a font that supports the OEM (Original Equipment Manufacturer) character set.
3-16 Establishing a Connection ■ Screen Scroll — Make sure that screen scroll is enabled. Again, this is the default in most terminal applications. Modem settings A majority of IRC connection problems are actually caused by improper configuration of the modem on the management console. If your terminal emulation application supports TAPI (like HyperTerminal), the application should configure the modem correctly using information in the Windows modem database.
3-17 ■ Callback Support — You need to manually place the modem in autoanswer mode if either of the following situations occur: ❏ callback authentication is required to complete your login ❏ you want IRC to automatically reestablish a connection following a remote power cycle Establishing a Connection After verifying the proper configuration of the terminal emulator settings, instruct the application to dial into the managed server.
3-18 Establishing a Connection Login After a connection has been established using one of the management applications described above, and the call has been validated by pressing Enter three times, IRC responds by displaying a login prompt, as shown in Figure 3-8. Figure 3-8. Remote Console displays login prompt after successful call identification To log in to IRC: 1. Enter a valid username, then press Enter. 2. Enter a valid password, then press Enter.
3-19 If you established your connection using any standard terminal emulation program that supports ANSI, the Integrated Remote Console application main menu displays as shown in Figure 3-9 after you have successfully logged in. Figure 3-9. Remote Console Main Menu Compaq Integrated Remote Console User Guide Writer: Caroline Juszczak Project: Compaq Integrated Remote Console User Guide Comments: 281862-00x File Name: D-CH03.
3-20 Establishing a Connection If you established your connection with Insight Manager through the Remote Console menu option, Insight Manager automatically switches you into Remote Console mode following login, as shown in Figure 3-10. To return to the main menu, simply click Switch Consoles, located at the bottom of the Insight Manager terminal window. Figure 3-10.
4-1 Chapter 4 Using Integrated Remote Console Use the instructions in Chapter 3 to establish a connection to the managed server and to log in to Integrated Remote Console (IRC). If you establish your connection using an application other than Compaq Insight Manager, the Integrated Remote Console Main Menu displays, as shown in Figure 4-1, after you have successfully logged in. Figure 4-1. Remote Console Main Menu The Main Menu is the main control center for the various functions available through IRC.
4-2 Using Integrated Remote Console If you establish your connection through the “Remote Console” menu option within Insight Manager, you are automatically switched into Remote Console mode following login, as shown in Figure 4-2. To return to the Main Menu, simply click Switch Consoles, located at the bottom of the Insight Manager terminal window. Figure 4-2. Remote Console mode Writer: Caroline Juszczak Project: Compaq Integrated Remote Console User Guide Comments: 281862-00x File Name: E-CH04.
4-3 Main Menu Options The following options are available from the Main Menu. ■ Remote Console — Redirects the managed server’s console to the management console to provide the user with remote control capabilities, regardless of the software running on the managed server. ■ Reboot Server — Lets you reset the managed server. Use this only as a last resort; it performs an unconditional reset of the server.
4-4 Using Integrated Remote Console Remote Console Menu Option One of the primary control features offered by IRC is its ability to allow a user remote access to the managed server’s console. Enter remote console mode by selecting Remote Console… from the Main Menu. This can be done by positioning the cursor, then pressing Enter.
4-5 Beginning a Remote Console Session If the attention key and terminal size settings are correct, select Begin a Remote Console Session to enter the Remote Console mode. The managed server console is displayed if the following conditions are met: ■ The user has remote console access to the server. ■ The managed server is in text mode. If the managed server is in graphics mode, an appropriate message is displayed.
4-6 Using Integrated Remote Console Table 4-1 Key Functions for Navigating the IRC Menu System Key Function 1-9 Moves and selects the corresponding menu item ↑ or I Scrolls the highlighted selection up. The “I” key can be used to navigate the menus from ANSI terminal programs that do not support the up and down arrow keys. ↓ or M Scrolls the highlighted selection down. The “M” key can be used to navigate the menus from ANSI terminal programs that do not support the up and down arrow keys.
4-7 In this example, the attention key is defined to its default: Ctrl+A. To perform a down-arrow attention key sequence: 1. Hold the Ctrl key down while pressing the A key on the terminal keyboard. 2. Release both keys making sure to release the Ctrl key last. This informs IRC that you want to generate an enhanced key sequence. There is no change to the server console, since Remote Console is waiting for the next key to complete the sequence. 3. Press the M key.
4-8 Using Integrated Remote Console The terminal emulator interactively displays any changes to the server console as they are typed, as shown in Figure 4-5. Figure 4-5. Selecting MS DOS as the operating system Press Enter to select the operating system. Returning to the Main Menu To return to the Main Menu from remote console mode, you must enter an attention key sequence to distinguish this command from keys that might be valid or desired for server control.
4-9 In addition to the Switch Consoles feature, Insight Manager offers enhanced keyboard and terminal support. As a result, the function keys (F1-F12) and Alt sequences can be performed on the terminal console, without having to use attention sequences. In addition, the Insight Manager terminal window dynamically resizes itself to match the screen size of the server console. Windows NT, for example, changes between 25-line and 50-line mode during its boot process.
4-10 Using Integrated Remote Console When the Change Attention Key menu option is selected, IRC prompts you to enter a new attention key. A screen similar to Figure 4-6 is displayed. Figure 4-6. Change Attention Key screen The default attention key for a new user is Ctrl + A. If a user modifies the attention key, the modified value is saved in the user database. Different users can use different attention keys. An attention key may be any ASCII key, preferably a key that is infrequently used.
4-11 Most of the more advanced ANSI terminal emulation packages allow adjustment of the number of displayed rows. If this is the case, it is recommended that both the remote terminal and the terminal size settings be adjusted to accommodate the maximum number of lines which will usually be displayed on the server console.
4-12 Using Integrated Remote Console Reboot Server Menu Option It may become necessary to reboot a server that has gone off line and is no longer accessible through the OS. Compaq Automatic Server Recovery can be configured to reboot the server automatically when this condition is determined. In some instances, however, the administrator may want to control this reset event so that it can be interactively invoked and monitored.
4-13 This debug information can be easily captured for later analysis by using the Copy to Clipboard function of the terminal emulator application. In Insight Manager this can be done by clicking Copy, located at the bottom of the terminal window. From visual inspection of the server console, you can see that the operating system is off line. To restore this server to an online state, it must rebooted. This can be done by returning to the Main Menu and selecting the Reboot Server… menu option.
4-14 Using Integrated Remote Console In this example, the server is reset by selecting Reboot Server…. Remote Console prompts you for verification, since this unconditionally resets the server. Figure 4-9. Reboot Server warning Press Y to begin the server reboot process. Following the server reset event, Remote Console automatically places you in Remote Console mode so that you can interactively monitor the reset process.
4-15 Figure 4-10. Power Cycle warning Type Y to instruct Remote Console to attempt to automatically reestablish the connection upon power-up. Integrated Remote Console prompts for the phone number of the management console. After entering the phone number of the management console, you are prompted for verification one last time. Type Y to initiate the remote server power down sequence. Figure 4-11.
4-16 Using Integrated Remote Console If you are using Insight Manager as the terminal application, as shown in Figure 4-11, the reconnection is reestablished without user intervention. The Insight Manager terminal window is placed into “Callback mode”, indicated by the phrase “Waiting for Callback…” located in the status window. When power returns to the server, Remote Console uses the supplied phone number to attempt to reestablish a connection.
4-17 View Reboot Sequence Selecting the View Reboot Sequence option from the IRC Main Menu lets you view a stored boot sequence. The IRC boot sequence recorder starts automatically following an Automatic Server Recovery (ASR) event. The boot sequence contains all ROM POST messages and operating system load messages that were displayed on the managed server console while it was being rebooted.
4-18 Using Integrated Remote Console Figure 4-13. Reboot Replay Sequence screen You can adjust the playback speed using keys 1-9. The space bar can be used to stop/start the playback. After the sequence has been played, you are returned to the main menu. Pressing Esc terminates the sequence replay and immediately returns you to the main menu. Writer: Caroline Juszczak Project: Compaq Integrated Remote Console User Guide Comments: 281862-00x File Name: E-CH04.
4-19 View Event Log Select View Event Log from the Main Menu to view the IRC Event Log, as shown in Figure 4-14. Figure 4-14. Event Log screen If the event log contains multiple pages of information, you may navigate through these pages using Page Up, Page Down, Home, or End (or character equivalents).
4-20 Using Integrated Remote Console Additional events may be present or available through future firmware upgrades. To clear the contents of the event log, press Delete. To return to the Main Menu, press Esc. Change Password The Change Password option is available to users without supervisory access. These users are permitted to change their own passwords, but are prohibited from viewing or changing any other user attributes in the user database.
4-21 Manage Login Information Manage Login Information is available to users with supervisory rights. This option enables an administrator to add or delete users or modify an existing user’s configuration remotely. Select Manage Login Information to display a screen similar to that shown in Figure 4-16. Figure 4-16. Manage Login Information screen Press A to add a user. You are then prompted to fill in the added user information.
4-22 Using Integrated Remote Console Modify User Information After selecting a user from the Manage Login Information screen, a screen similar to the one in Figure 4-17 displays. For new users, all fields are set to defaults. Figure 4-17. Example: Modify User Information screen See “User Configuration” in Chapter 2 for a description of the various fields in the Modify User Information dialog box. To edit, position the highlight next to the desired field and press Enter to select.
4-23 Manage Configuration The Manage Configuration option, available to users with supervisory rights, allows an administrator to view or change the configuration parameters of IRC remotely. Since many configuration options are necessary for the proper operation of IRC, care must be exercised when making changes. Selecting Manage Configuration presents a screen similar to that shown in Figure 4-18. Figure 4-18.
4-24 Using Integrated Remote Console ■ Communications Setup… — Allows the administrator to view or change all communication parameters used by Integrated Remote Console. ■ System Information… — Displays hardware and firmware revision information pertaining to the managed server. ■ IRC Information — Displays hardware and firmware revision information pertaining to Integrated Remote Console.

4-25 NOTE: The Compaq System Configuration Utility helps in the initial setup of communications setup parameters. The following communications parameters can be changed from this screen: ■ Baud Rate ■ Data Bits ■ Stop Bits ■ Parity See Chapter 2 for detailed information on these parameters. To edit or select a particular item, position the highlight on the desired field and press Enter. To accept changes, select Save Modified Information. To reject changes, press Esc.
4-26 Using Integrated Remote Console From this screen, the administrator can change the strings used to initialize and communicate with the modem. See Chapter 2 for detailed information on the modem strings. To change any of the modem strings, position the highlight next to the desired field and press Enter. To accept changes made to these strings, select Save Modified Information. To restore default modem strings, select Restore Default Modem Strings. To cancel changes, press Esc.
5-1 Chapter 5 Using Attention Key Sequences You can use attention key sequences in Remote Console mode to maximize ANSI terminal emulation functionality. Integrated Remote Console (IRC) provides a mechanism to enter complicated key sequences otherwise unavailable from a standard ANSI terminal emulation program. This mechanism consists of key sequences where you press a configurable “attention key” followed by a standard ANSI key.
5-2 Using Attention Key Sequences Attention Key Command Sequences These sequences, listed in Table 5-1, issue an instruction to IRC from within remote console mode. Table 5-1 Attention Key Command Sequences Key Command [Atn] Esc Exits the Remote Console mode and displays the IRC Main Menu. [Atn] Space Instructs the Integrated Remote Console application to refresh the server console screen on the remote terminal.
5-3 Attention Key Support Sequences These sequences emulate special PC keyboard keys that are not part of the ANSI standard, such as function keys and Page Up and Page Down. Table 5-2 lists the attention key sequences for entering special non-ANSI key sequences from any ANSI terminal program. Included are keys such as Home, End, Page Up, Page Down, and function and arrow keys.
5-4 Using Attention Key Sequences Attention Key Support Sequences Continued Key Key it is equal to on the server console [Atn] , (comma) Page Down [Atn] U Home [Atn] N End [Atn] [Atn] Generates a literal Atn sequence to the server console. For instance, if the attention key was assigned to Ctrl + A, but an actual Ctrl + A was required as input to the server console, the user could insert a literal Ctrl + A by pressing this sequence twice.
5-5 Attention Key Compose Sequences These sequences extend the ability to enter complex keyboard sequences necessary in the PC environment, like Ctrl + Alt + Delete. Table 5-3 identifies keystroke sequences used to enter complex keyboard commands. These settings are automatically cleared after an ANSI key is entered, or if the Sequence Clear or Sequence End attention code is entered. Table 5-3 Attention Key Compose Sequences Key Function [Atn] A Emulates holding down the left Shift key.
5-6 Using Attention Key Sequences Example: Entering Alt + P For example, if you needed to enter a command such as Alt + P on the managed server: 1. Enter the attention key. In this example the attention key is set to its default: Ctrl+A. Press both the Ctrl and the A keys down simultaneously. Release both keys, making sure to release the Ctrl key last. 2. Enter the command to press and hold the Alt key on the managed server’s keyboard. This command key is X. 3. Press P.
5-7 Example: Entering Ctrl + Alt + Del The attention key compose sequences can be combined together and with other attention key support sequences to compose virtually any key combination. For example, if you needed to perform a Ctrl + Alt + Del key sequence on the managed server: 1. Enter the attention key. In this example the attention key is set to its default: Ctrl+A. Press both the Ctrl and the A keys down simultaneously. Release both keys, making sure to release the Ctrl key last. 2.
5-8 Using Attention Key Sequences More Attention Key Examples Table 5-4 summarizes how to compose some common key sequences within the Remote Console mode from any ANSI terminal program. The abbreviations L-Shift, L-Ctrl, and L-Alt are used to represent Left-Shift, Left-Ctrl, and Left-Alt respectively. Similarly, R-Shift, R-Ctrl, and R-Alt represent RightShift, Right-Ctrl, and Right-Alt, respectively.
5-9 Attention Key Template Figure 5-1 illustrates the layout of the attention key sequences. Essentially the attention key places the keyboard in an alternate mode, much like the “altfunction” keys on a laptop keyboard. Note the geographic placement of these sequences as seen on an U.S. domestic keyboard layout.

6-1 Chapter 6 Additional Modem Information Integrated Remote Console (IRC) has been tested and is compatible with a wide variety of internal and external modems. IRC requires a high-speed (14400 baud or greater) Hayes-compatible serial modem. Virtually all external RS-232 serial modems meet this requirement. Modem Types Internal modems must be ISA and must be controller-based. The following sections describe many of the commercially available types of modems and their compatibility with IRC.
6-2 Additional Modem Information External Serial Modems IRC supports most external high-speed serial modems. Some modems, like the Compaq Microcom 510, offer both a serial and parallel (APT) interface. Such modems must be connected through the serial interface to operate correctly with IRC. External modems are cabled to the managed server using a standard straightthrough DTE to DCE style cable. A standard DB-9F to DB-25M cable can be used and there are no specific requirements specific to IRC.
6-3 Internal ISA Plug-n-Play Modems Internal ISA Plug-n-Play modems, designed for the PC consumer industry, are designed to be easy to install and configure. Such modems rely on the operating system for resource configuration, eliminating the need for the user to set predetermined jumpers. The modem’s COM port and interrupt settings are automatically configured by the operating system and can be adjusted at runtime to resolve resource conflicts when new hardware is installed.
6-4 Additional Modem Information PCI-based Modems PCI-based modems have recently been introduced to the industry to replace the need for internal modems in computers without ISA slots. Most PCI-based modems are based on proprietary “windows” modem interfaces and are not supported by IRC (see above on “windows” modems). If an internal modem is desired, use a controller-based ISA modem. If an ISA modem is unable to be accommodated, use an external serial modem.
6-5 Modem Configuration Strings For IRC to function correctly, the modem must be configured correctly. The modem is configured using the primary and secondary initialization strings, which are specified during the configuration process. For many modems, the proper initialization strings can be found in Appendix A. This section provides the information necessary to determine the proper initialization strings for modems not listed in this chapter.
6-6 Additional Modem Information Computer to Modem Serial Port Speed Some modems have a configuration option that controls whether the DTE serial port interface is fixed at a predetermined baud rate or changed dynamically based upon the modem to modem connect rate. In “floating DTE” mode, the Computer to Modem speed is automatically adjusted based upon the Modem to Modem negotiated baud rate. For IRC to operate properly, the DTE (server to modem) baud rate must be set to fixed.
6-7 Data Terminal Ready (DTR) Interpretation Most modems have a configuration option that controls the interpretation of the DTR serial port interface signal. For IRC to function properly, the modem must be configured to terminate a connection whenever DTR is dropped. Improper setting of this configuration option results in the improper termination of an existing IRC session and may result in the inability to establish a future IRC connection. The &D AT command controls this setting in most modems.
6-8 Additional Modem Information Data Compression Most high-speed modems also try to negotiate a compression protocol such as v.42 bis or MNP5 upon establishing a connection to another modem. Compression settings do not effect the ability to connect to IRC. However, negotiating such a protocol is advantageous, since it greatly accelerates responses from the server, particularly in remote console mode.
7-1 Chapter 7 Direct Connections In a data-center environment, connecting a modem to each server may be undesirable. For this reason, Integrated Remote Console (IRC) supports configurations whereby access can be obtained through companion hardware, such as a “buddy server” or terminal server. In a “buddy server” configuration, two servers are directly connected to each other’s serial ports. If either server fails, the other server can be used to gain out-of-band access to the failing one.
7-2 Direct Connections Cable Requirement For proper communication, IRC requires a null-modem cable with a complete set of modem control signals. The exact wiring diagram for this cable is shown in Appendix B. Cables are occasionally labeled as “null-modem” which do not conform to this diagram. Check with your cable vendor to ensure that the cable meets the requirements shown in Appendix B. Cables that differ from this specification may not function correctly.
7-3 ■ DTR Control — For compatibility with IRC, the terminal must assert DTR whenever a communication session is open. IRC uses the DCD control signal (which is driven by the terminal’s DTR output) to determine whether a remote session is open. IRC ignores any serial port activity whenever DCD is inactive. Consequently, if the terminal does not assert it’s DTR output, it is impossible to establish a connection with IRC. Conversely, the terminal must lower DTR whenever a communication is closed.
7-4 Direct Connections Connecting Using a Terminal Server or Concentrator A terminal server can be a perfect compliment to IRC, particularly in a datacenter environment where servers are grouped in clusters. Through one terminal server, a remote administrator can gain access to a number of different servers either through a shared modem or through a local area network connection. This topology greatly decreases or eliminates the need for multiple modems and phone lines.
7-5 Such an implementation has three requirements: 1. You must select or obtain an appropriate cable or adapter to connect the terminal server asynchronous serial port to the managed server DB-9F serial port. 2. You must properly configure the IRC feature of each server for this environment. 3. You must configure each port of the terminal server with the necessary serial port settings. Each of these requirements is described in detail in the following sections.
7-6 Direct Connections IRC requires a complete null-modem cable connection to operate correctly. For proper connectivity, the serial port signals must be wired in a fashion identical to the diagram shown in Appendix B. As shown in the diagram, the managed server serial port transmit (TX or TxD) must be wired to the serial port receive (RX or RxD) of the terminal server.
7-7 Connector Example To demonstrate the proper adapter, a serial port found on the Cisco 2509/2511 terminal server is used as an example. On this terminal server, a breakout cable provides the serial port connectivity through individual RJ-45 style connectors.
7-8 Direct Connections Using the information provided above from the terminal server manufacturer and the cable specified in Appendix B, the following adapter can be obtained.
7-9 ■ Integrated Remote Console Communication Device Settings — Set the communication device to direct connect and ensure that the communication device COM port and interrupt settings match the serial port selected above. ■ Integrated Remote Console Sharing Options — In instances where a terminal server is used, in-band management information is typically available directly through a LAN connection.
7-10 Direct Connections ■ Flow Control — Configure each port on the terminal server for hardware flow control. If the receive and transmit functions are each configurable, make sure they are both set for hardware flow control. An improper flow control setting could result in the loss of characters, causing the remote terminal to display incomplete or garbled information. ■ DTR Control — This setting is crucial to the operation of the Integrated Remote Console.
8-1 Chapter 8 Modem Sharing The modem sharing feature of Integrated Remote Console (IRC) allows you to use the same modem for hardware and operating system-based management. If asynchronous management is installed on the managed server, the management console can remotely monitor and receive traps from the managed server through an operating system-based dial-up connection on the shared modem.
8-2 Modem Sharing Asynchronous Management Asynchronous Management is a Compaq software option that allows you to monitor server health and receive traps through an asynchronous (modem) connection. This feature is essential to properly manage remote servers that may not be connected through a local area network. For servers with a LAN connection, this feature provides an important backup communication path in instances when the network is down.
8-3 A general outline of the configuration process is shown below. 1. Disable IRC — It is highly recommended that IRC be disabled before the operating system based utilities are installed. This step is not required, but can eliminate communication problems introduced by an incorrectly configured IRC. 2. Install and Configure Dial-up Networking — Install PPP communication software on the managed server.
8-4 Modem Sharing 7. Test OS Dial-out Capability —Test the operating system’s ability to dial out by sending a test trap using the “test” feature of the asynchronous communication software. Again, test the connection several times, allowing at least 60 seconds to transpire between connections. 8. Test IRC Dial-in Capability — Finally, test the ability to invoke the IRC login prompt by dialing into the server using an ANSI or telnet based client application.
8-5 3. Install and Configure Graphical Remote Control Application — Install graphical remote control application using directions supplied by the software vendor. Configure the host for network TCP/IP access. The client application should also be configured for TCP/IP access, specifying the managed server’s PPP IP address or server name. 4. Test Dial-up Networking and Graphical Remote Control — Once configured, test the configuration by dialing into managed server.
8-6 Modem Sharing Additional Information Determining Proper Initialization Strings in a Windows NT 4.0 RAS Environment Each modem supported under Windows NT is uniquely described by an entry in a modem information file (*.INF). This file, which is either provided by Microsoft as part of the Windows NT installation or provided by the modem vendor, contains specific configuration information necessary for Windows NT applications to fully utilize the modem.
8-7 Temporarily disable IRC If IRC is enabled, temporarily disable IRC using the Compaq System Configuration Utility. This prevents incorrect settings from interfering with RAS. Turn on Modem Log File 1. From the Windows Control Panel, double-click on Modems. 2. From the Modem Properties dialog box, select the modem that you want to share with IRC and click Properties. 3. Click the Connection tab control. Click Advanced to display the Advanced Connection Settings dialog box. 4.
Modem Sharing 8-8 Locate the Modem Initialization Strings The modem log file should contain information similar to the following: Line # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 01-19-1998 16:45:03.526 Serial in use. 01-19-1998 16:45:03.526 Fax Modem Serial 01-19-1998 16:45:03.526 01-19-1998 16:45:03.526 01-19-1998 16:45:03.526 01-19-1998 16:45:03.526 01-19-1998 16:45:03.536 01-19-1998 16:45:03.536 01-19-1998 16:45:03.866 01-19-1998 16:45:03.866 01-19-1998 16:45:03.
8-9 The initialization strings invoked by Remote Access Server are located between the “Initializing modem” and “Waiting for a call” lines in the modem log file. Typically, there are three or four AT command sequences listed. The last command sequence is usually constructed using the options you have selected in the Modem Properties dialog box. This string usually contains entries for compression, error control, timeout settings, and so on.
A-1 Appendix A Suggested Modem Settings The following tables provide suggested settings for when a modem is dedicated or shared in non-Windows-NT environments, and when the modem is shared in a Windows NT 4.0 environment. NOTE: Some of the initialization string entries in Tables A-1 and A-2 may be too long to be completely displayed on one line and consequently wrap to another line. When entering the string into IRC’s modem configuration, combine wrapped lines into one string.

C-2 Troubleshooting POST Errors Server displays “172-2 IRC Configuration Invalid” message during POST Explanation: Before initializing, IRC does a quick check of the configured communications device before using it. If the configuration settings do not match a valid COM port, you receive the above message followed by either “COM Port Invalid,” “Incorrect IRQ,” or “PCI COM Port.
C-3 Connection Problems Due to the complexity and diversity of communications hardware, you may experience problems reliably connecting to IRC. A majority of these problems are due to improper configuration settings and can usually be remedied quickly by correcting the configuration error. The following section guides you through some possible configuration errors and their remedies.
C-4 Troubleshooting ■ Make sure the COM port and interrupt settings of IRC exactly match the hardware jumper settings on the internal modem, or integrated serial port settings if connecting to an external device. ■ Make sure that the value for Maximum Baud Rate is compatible with your modem. This setting should normally be 19200 for 14.4k modems, 38400 for 28.8k modems, and 57600 or 115200 for 33.6k, and 56k modems. ■ Make sure IRC is configured for either an Internal Modem or External Modem.
C-5 ■ If you are using Compaq Insight Manager as the terminal application and have either a Compaq SpeedPaq 33.6 or U.S. Robotics modem installed in the management console, change the “initialize” string under Insight Manager’s COM port setup from “AT&F&C1&D2E0S0=0” to “AT&F1&C1&D2&B1E0S0=0”. This selects the hardware-flow control template and also specifies a fixed DTE baud rate. ■ If you have either a Compaq SpeedPaq 33.6 or U.S.
C-6 Troubleshooting Connection problems using a modem in shared mode If you are unable to login to the IRC in shared mode, it is strongly recommended that you first troubleshoot the problem with modem sharing options set to dedicated. Once proper operation has been verified, return to shared mode and proceed in this section if the problem still exists.
C-7 ■ If the modem is not configured correctly in the operating system, the operating system may fail to communicate with the modem and periodically retry this operation. These periodic attempts will gain ownership of the modem from IRC making it unavailable for login. Check for proper operation of the modem by temporarily disabling IRC. When proper operation with the operating system has been verified, reenable IRC.
C-8 Troubleshooting ■ If you are using a Compaq SpeedPaq 56K or Rockwell-based 56k-flex modem in the managed server, make sure that you have upgraded the modem firmware to the latest version offered by the modem manufacturer. Early 56kflex firmware versions (before 1.12) incorrectly generate the data carrier detect signal (DCD) while the modem is reporting the connect string. This interferes with the reception of the carriage return sequence necessary to invoke the login prompt.
C-9 Cannot dial into operating system-based management in shared mode You can connect to IRC, but attempts to dial into the server’s operating system fail. Explanation: If an incoming call is not positively identified as destined for Integrated Remote Console, the call is forwarded to the operating system. Integrated Remote Console uses its configured initialization strings to reset the modem after it regains ownership.
C-10 Troubleshooting Connection problems using a directconnection Cannot obtain a login prompt using a direct-connection After opening a direct serial connection to IRC, a login prompt does not appear on the management console after three carriage returns are entered. Explanation: In direct connect mode, IRC waits for three carriage returns to invoke the login prompt after the data carrier detect (DCD) signal is driven active by the terminal or terminal server.
C-11 ■ Try the connection again following a cold power-cycle of the managed server. If the problem only occurs after the server is warm-booted, obtain the latest system ROM upgrade for your server. Integrated Remote Console firmware versions 1.51 and greater fix a problem where IRC is unavailable following a warm boot. Problems while using IRC Screen temporarily pauses during menus or remote console text Screen inexplicably pauses for several seconds while menus or remote console text is being drawn.
C-12 Troubleshooting Terminal loses characters or doesn’t paint correctly in Remote Console Mode Terminal contains a jumbled representation of the managed server’s screen, particularly after heavy video activity (large number of scrolls or repaints) on the managed server. Explanation: IRC uses hardware RTS/CTS handshaking to control the data rate to the management console.
C-13 “View Reboot Sequence” is grayed out Menu item “3. View Reboot Sequence” is gray and cannot be selected. Explanation: The “View Reboot Sequence” menu option is only available if IRC contains a valid boot sequence. The boot sequence recorder is only activated under certain conditions. See Chapter 4 “View Reboot Sequence” for more information on this feature.
