5 System Setup Utility: When to Run The System Setup Utility (SSU) is on the Server System Configuration Software CD shipped with the server. The SSU provides a graphical user interface (GUI) over an extensible framework for server configuration.
PAGE 59
AC450NX Rack Server System Product Guide The SSU uses the information provided by .CFG files, configuration registers, flash memory, and the information that you enter, to specify a system configuration. The SSU writes the configuration information to flash memory. The SSU stores configuration values in flash memory. These values take effect when you boot the server. POST checks the values against the actual hardware configuration; if they do not agree, POST generates an error message.
PAGE 60
Chapter 5 System System Setup Utility: When to Run • Running the SSU Remotely To run the SSU remotely, you must invoke the SSU.BAT file with the /t switch and redirect the text-mode output via BIOS console redirection. The /t switch puts the display in text mode and allows the console to be viewed and controlled via BIOS console redirection. First, configure the server for BIOS console redirection. Then configure the modem to auto-answer and to “modem reaction to DTR set to return to command state.
PAGE 61
AC450NX Rack Server System Product Guide Customizing the SSU The SSU lets you customize the user interface according to your preferences. The AF sets these preferences and saves them in the AF.INI file so that they take effect the next time you start the SSU. There are four user-customizable settings. ✏ NOTE If you run the SSU from nonwritable media like a CD, these preferences will be lost when you exit the SSU.

PAGE 79
AC450NX Rack Server System Product Guide How EMP Console Works The EMP shares use of the COM 2 port with the system on the server. When the EMP has control of the port, the port operates in command mode. When the system has control, the port operates in console redirect mode. When connecting to a server, the EMP Console checks to determine the mode of the COM 2 port. The following discussion covers how EMP Console functions in each mode: • • Command mode is the default COM 2 state.
PAGE 80
Chapter 7 Emergency Management Port Console: How to Use Figure 7-2. EMP Console in Redirect State Figure 7-2 shows the EMP Console window in redirect mode with the terminal window. The text that appears on the server monitor displays in the Redirect window. Availability of the various EMP Console features are determined by two factors: the BIOS EMP access mode and whether the server’s COM 2 port is configured for console redirection. The three EMP access modes are: disabled, pre-boot, and always active.
