Port Configuration Port Configuration The asynchronous/synchronous ports are configured as either asynchronous or synchronous. The default is a synchronous port configuration. Asynchronous/Synchronous Port Features The low-speed asynchronous/synchronous ports connect terminals, printers, modems, microcomputers, and remote LANs over asynchronous serial lines to an internetwork, or to synchronous devices such as DSU/CSUs on the same ports.
Communications Server Services • • • PPP SDLC X.25 Communications Server Services The multiport router acts as a communications server to connect terminals, printers, modems, microcomputers, and remote LANs over asynchronous serial lines to an internetwork. The communications server uses a set of connection services to allow remote networks access to an internetwork of LANs and WANs.
Communications Server Services Figure 1-5 Remote Node Services—Example Network SLIP PPP ARA H7297 Plain old telephone system Terminal Services Terminal services provide terminal-to-host connectivity with virtual terminal protocols including Telnet, rlogin, local-area transport (LAT), TN3270, and X.25 packet assembler/disassembler (PAD). Terminal services can be used to connect to a modem in a modem pool for outbound connectivity. Figure 1-6 shows an example network.
Communications Server Services Asynchronous Routing Services Routing services enable the multiport router to route packets over LANs and WANs using the asynchronous interfaces. A key benefit of asynchronous routing is that it provides low-cost operation by using dialup telephone networks only when needed. Figure 1-7 shows an example network.

C H A PT E R 2 Preparing to Install the Router This chapter describes important information to consider before you begin to install the router, and includes the following sections: • • • • • Safety Recommendations General Site Requirements Preparing to Connect to a Network Preparing to Connect to a Network Inspecting the System Safety Recommendations Follow these guidelines to ensure general safety: • • • • Keep the chassis area clear and dust-free during and after installation.
Safety Recommendations Warning Ultimate disposal of this product should be handled according to all national laws and regulations. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.) Maintaining Safety with Electricity Follow these guidelines when working on equipment powered by electricity.
Safety Recommendations • • Do not work alone if potentially hazardous conditions exist. Never assume that power is disconnected from a circuit. Always check. Warning Read the installation instructions before you connect the system to its power source. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.
General Site Requirements Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 to 10 megohms (Mohms). General Site Requirements This section describes the requirements your site must meet for safe installation and operation of your system. Ensure that your site is properly prepared before beginning installation. Site Environment The router can be placed on a desktop or mounted in a rack or on a wall.
General Site Requirements Preventive Site Configuration The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures. • Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Ensure that the room in which you operate your system has adequate air circulation.
Preparing to Connect to a Network Power Supply Considerations Check the power at your site to ensure that you are receiving “clean” power (free of spikes and noise). Install a power conditioner if necessary. Warning The device is designed to work with TN power systems. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.
Preparing to Connect to a Network Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.
Preparing to Connect to a Network Table 2-1 Typical DTE and DCE Devices Device Type Gender Typical Devices DTE Male1 Terminal PC Router DCE Female 2 Modem CSU/DSU3 Multiplexer 1. If pins protrude from the base of the connector, the connector is male. 2. If the connector has holes to accept pins, the connector is female. 3. CSU/DSU = Channel service unit/data service unit.
Preparing to Connect to a Network Balanced drivers allow EIA/TIA-449 signals to travel greater distances than the EIA/TIA-232 signals. Table 2-3 lists the maximum speeds and distances for EIA/TIA-449, which are also valid for V.35, X.21, and EIA-530 signals. Table 2-3 EIA/TIA-449, V.35, X.
Preparing to Connect to a Network Note All serial ports configured as DTE require external clocking from a CSU/DSU or other DCE device. Figure 2-1 shows the serial transition cables you can connect to the serial port on the rear panel of the router.
Preparing to Connect to a Network Figure 2-1 Serial Transition Cables H2485 Router connections EIA/TIA-232 EIA/TIA-449 V.35 X.21 EIA-530 Network connections at the modem or CSU/DSU Although attempting to manufacture your own serial cables is not recommended (because of the small size of the pins on the DB-60 serial connector), cable pinouts are provided in the appendix “Cable Specifications.
Preparing to Connect to a Network EIA/TIA-232 Connections The EIA/TIA-232 standard supports unbalanced circuits at signal speeds up to 64 kbps. The serial port (labeled “SERIAL”) supports synchronous connections. The console and auxiliary ports also use an EIA/TIA-232 connection; however, the console and auxiliary ports support asynchronous connections. The network end of the EIA/TIA-232 serial transition cable (not included) provides a DB-25 connector, as shown in Figure 2-2.
Preparing to Connect to a Network The network end of the EIA/TIA-449 serial transition cable (not included) provides a DB-37 connector, as shown in Figure 2-3. The end that connects to the serial port on the rear panel of the router has a DB-60 connector. EIA/TIA-449 serial transition cables are available with a DB-37 connected in either DTE or DCE mode. To order a cable, see the section “Obtaining Service and Support” in the “Overview of the Router” chapter.
Preparing to Connect to a Network Figure 2-4 V.35 Serial Transition Cable Connectors, Network End DCE H1616a DTE X.21 Connections The X.21 connector uses a 15-pin connector for balanced circuits and is commonly used in the United Kingdom to connect to the public data network. X.21 relocates some of the logic functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232. The network end of the X.
Preparing to Connect to a Network EIA-530 Connections The EIA-530 standard, which supports balanced transmission, provides the increased functionality, speed, and distance of EIA/TIA-449 on the smaller, DB-25 connector used for EIA/TIA-232, instead of the 37-pin connector used for EIA/TIA-449. Like EIA-TIA-449, EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423.
Preparing to Connect to a Network Ethernet Connections The IEEE has established Ethernet as standard 802.3. The most common Ethernet implementations are as follows: • 10Base5 (AUI)—Ethernet on thick coaxial cable, also known as thick Ethernet. The maximum segment distance is 1,640 feet (500 meters). • 10Base2 (Thinnet)—Ethernet on thin coaxial cable, also known as thin Ethernet. The maximum segment distance is 607 feet (185 meters). • 10BaseT—Ethernet on unshielded twisted-pair (UTP) cable.
Preparing to Connect to a Network BRI Connections On models with a Basic Rate Interface (BRI) port, the BRI port is an RJ-45 8-pin connector located between the UTP and console ports on the Cisco 2520 and Cisco 2521, or between the 10BT and console ports on the Cisco 2522 and Cisco 2523. Use an appropriate cable to connect the system directly to the Integrated Services Digital Network (ISDN) through the NT1.
Preparing to Connect to a Network The main difference between the console and auxiliary ports is that the auxiliary port supports hardware flow control and the console port does not. Flow control paces the transmission of data between a sending device and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more.
Inspecting the System Inspecting the System Do not unpack the router until you are ready to install it. If the final installation site will not be ready for some time, keep the chassis in its shipping container to prevent accidental damage. When you have determined where you want the router installed, proceed with unpacking it, and continue using the chapter “Installing the Router.

C H A PT E R 3 Installing the Router This chapter describes the tasks you must perform to install the router, and includes the following sections: • • • • • Tools and Equipment Required Setting Up the Chassis Connecting the DC Power Supply Connecting the Console Terminal and Modem What to Do after Installing the Router Hardware Tools and Equipment Required Installation requires some tools and equipment that are not included as standard equipment with the router.
Setting Up the Chassis Note For cable ordering information, see the section “Obtaining Service and Support” in the “Overview of the Router” chapter. • Ethernet 10BaseT hub or PC with a network interface card for connection to the Ethernet AUI (LAN) port. • • • Token Ring Media Attachment Unit (MAU) for connection to the Token Ring port. • Modems for connection to the asynchronous serial ports. CSU/DSU or other DCE device for connection to the synchronous serial interface.
Setting Up the Chassis Figure 3-1 Identifying the Rubber Feet H4796 Rubber feet (5) Black adhesive strip Step 2 Place the chassis upside down on a smooth, flat surface. Step 3 Peel off the rubber feet from the black adhesive strip and place them adhesive-side down onto the five round, recessed areas on the bottom of the chassis, as shown in Figure 3-2.
Setting Up the Chassis Step 4 Place the router right-side up on a flat, smooth, secure surface. Do not place anything on top of the router that weighs more than 10 pounds (4.5 kg). Excessive weight on top could damage the chassis. Caution Rack-Mounting the Chassis This section describes the procedures for rack-mounting the chassis. The chassis comes with brackets for use with a 19-inch rack or, if specified in your order, optional larger brackets for use with a 24-inch rack.

Setting Up the Chassis Installing in a Rack After the brackets are secured to the chassis, you can rack-mount it. Using the screws you provide, attach the chassis to the rack as shown in Figure 3-7. Figure 3-7 Attaching the Chassis to a Rack—Rear Panel Forward 19 in. brackets H6331 24 in. brackets Wall-Mounting the Chassis Use the smaller brackets (for use with a 19-inch rack) to wall-mount the chassis. The smaller brackets provide the most stable position for the chassis.
Setting Up the Chassis Step 2 Attach the chassis assembly to the wall as shown in Figure 3-9, using screws and anchors that you provide. We recommend the following: • For the best support of the chassis and cables, attach the brackets so that the screws align with a vertical wall stud. (See Figure 3-9.) This position will prevent the chassis from pulling away from the wall when cables are attached. • For the best ventilation of the chassis, mount the chassis with the power supply and fan at the top.

Connecting the DC Power Supply Connecting the DC Power Supply The multiport serial router has an optional direct current (DC) power supply. This section describes the DC power supply specifications and wiring. DC Power Specifications The DC power supply is intended for use in DC operating environments. Table 3-1 lists the power supply specifications. Table 3-1 DC Power Supply Specifications Description Design Specification Power 40W, –40 to –72 VDC Wire gauge for power connections 14 AWG1 1.
Connecting the DC Power Supply Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off position, and tape the switch handle of the circuit breaker in the off position. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.
Connecting the DC Power Supply Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.
Connecting the DC Power Supply Figure 3-10 DC Power Supply Connections Input: –40– –72V Current: 1.5 –1.
Connecting to a Network For additional information on power supplies refer to the section “Troubleshooting the Power and Cooling Systems” in the appendix “Troubleshooting the Router.” Connecting to a Network This section explains how to connect the router to your LAN and a WAN. The cables required to connect the router to a network are not provided. To order a cable, see the section “Obtaining Service and Support” in the “Overview of the Router” chapter.

Connecting to a Network You can also connect the Token Ring port (RJ-45) to a Token Ring hub. If the transmission rate of your Token Ring network is 4 Mbps, use a UTP cable to connect the Token Ring port (RJ-45) to a Token Ring hub. If the transmission rate of your Token Ring network is 16 Mbps, use a STP cable to connect the Token Ring port (RJ-45) to a Token Ring hub.
Connecting to a Network Step 3 If you will be using AutoInstall to configure the router, connect the synchronous serial port (DB-60) to a CSU/DSU or other DCE device, as shown in Figure 3-13. If you do not plan to use AutoInstall (or you are not sure what AutoInstall is) do not connect the WAN cable until after you have configured the router. If a WAN cable is connected when you power ON the router for the first time, it will attempt to run AutoInstall to download a configuration file from a TFTP server.
Connecting to a Network Step 4 Connect one end of each asynchronous/synchronous cable to the asynchronous/synchronous ports (labeled SERIAL n (A/S)), and then connect the other end to a CSU/DSU or asynchronous device. (See Figure 3-14.) For asynchronous/synchronous port pinouts, refer to the appendix “Cable Specifications.
Connecting to a Network Step 5 Connect the ISDN BRI port (RJ-45) to an NT1 device.

(See Figure 3-17.
What to Do after Installing the Router Hardware What to Do after Installing the Router Hardware After you have installed the router, proceed to the chapter “Configuring the Router,” for software configuration information. Note Refer to the Cisco configuration guide and command reference publications for additional software configuration information. These publications are available on the documentation CD that came with the router or you can order printed copies.
4 CHAPT E R Configuring the Router This chapter describes the procedures for configuring the model 2520, model 2521, model 2522, and model 2523 routers, and contains the following sections: • • • • • Booting the Router for the First Time Configuring the Router Specifying the Boot Method Checking the Configuration Settings Getting More Information This chapter provides minimum software configuration information; it is not meant to provide comprehensive router configuration instructions.
Configuring the Router by the configuration register setting. The factory-default setting for the configuration register is 0x2102, which indicates that the router should attempt to load a Cisco IOS image from Flash memory. 3 If after five attempts a valid Cisco IOS image is not found in Flash memory, the router reverts to boot ROM mode (which is used to install or upgrade a Cisco IOS image). 4 If a valid Cisco IOS image is found, then the router searches for a valid configuration file.
Configuring the Router Using Configuration Mode You can configure the router manually if you prefer not to use the setup facility or AutoInstall. Take the following steps to manually configure the router in configuration mode: Step 1 Connect a terminal by following the instructions described in the section “Connecting the Console Terminal and Modem” in the chapter “Installing the Router” and then power up the router.
Configuring the Router To make your changes permanent, enter the copy running-config startup-config command at the enable prompt: Router# copy running-config startup-config The results of the show running-config and show startup-config commands differ if you have made changes to the configuration but have not yet written them to NVRAM. The router is now configured and will boot with the configuration you have entered.
Configuring the Router If the AutoInstall process is successfully completed, continue to Step 3 to write the configuration data to the multiport serial router’s nonvolatile random-access memory (NVRAM). If the Autoinstall process is not successfully completed, contact your system administrator for assistance.
Configuring the Router Step 2 After booting from Flash memory, the following information appears after about 30 seconds. Note The messages displayed vary, depending on the Cisco IOS release and feature set you selected. The screen displays in this section are for reference only and may not exactly reflect the screen displays on your console. When the following information is displayed, you have successfully booted the router: System Bootstrap, Version X.

Bridging software. Authorized for Enterprise software set. (0x0) 1 Ethernet/IEEE 802.3 interface. 2 Serial network interfaces. 8 low-speed (sync/async) network interfaces. 32K bytes of non-volatile configuration memory.
Configuring the Router A typical configuration using IP, IPX, and AppleTalk follows: Configuring global parameters: Enter host name [Router]: router Step 5 Enter the enable secret password, the enable password, and the virtual terminal password: The enable secret is a one-way cryptographic secret used instead of the enable password when it exists. Enter enable secret : shovel The enable password is used when there is no enable secret and when using older software and some boot images.
Configuring the Router Enter yes or press Return (the default) to configure IP, and then select an interior routing protocol for IP: Configure IP? [yes]: Configure IGRP routing? [yes]: Your IGRP autonomous system number [1]: 15 Configure CLNS? [no]: Configure bridging? [no]: Configure IPX? [no]: yes Configure XNS? [no]: Configure Apollo? [no]: Step 8 Enter the ISDN BRI switch type for the router. The ISDN switch type appropriate for the router depends on the ISDN provider’s equipment.

If an ISDN BRI WAN module is not installed in your router, skip this section and proceed with the next section, “Configuring the Ethernet or Token Ring Interfaces.
Configuring the Router In this example, routing is enabled on AppleTalk and IPX; IP has already been selected: Configure AppleTalk? [no]: yes Multizone networks? [no]: yes Configure LAT? [yes]: no Configure IPX? [no]: yes Configuring the Ethernet or Token Ring Interfaces Take the following steps to configure the Ethernet or Token Ring interface to allow communication over a LAN. To configure the interface parameters, you need to know the Ethernet or Token Ring interface network addresses.
Configuring the Router Step 3 If IPX is enabled on this interface, enter the unique IPX network number: Configure IPX on this interface? [no]: yes IPX network number [1]: B001 Configure XNS on this interface? [no] Configuring the Synchronous Serial Interfaces The synchronous serial interfaces are configured to allow connection to WANs through a CSU/DSU. All serial ports on the multiport serial router are initially configured as synchronous ports.
Configuring the Router Step 3 Configure the second synchronous serial interface: Configuring interface Serial1: Is this interface in use? [no]: yes Configure IP unnumbered on this interface? [no]: yes IP address for this interface: 172.16.74.2 Number of bits in subnet field [8]: Class B network is 172.16.0.0, 8 subnet bits; mask is 255.255.255.
Configuring the Router Entering this command saves the configuration settings that the setup process created in the router. If you fail to do this, the configuration is lost the next time the router is loaded. Setting Asynchronous Serial Ports The ports you plan to use as low-speed asynchronous serial ports must be reconfigured after the initial setup because the ports are initially configured as low-speed synchronous serial ports.
Configuring the Router Setting Synchronous Serial Ports Take the following steps to configure a low-speed asynchronous serial port to be a low-speed synchronous serial port: Step 1 Connect a terminal by following the instructions in the section “Connecting the Console Terminal and Modem” in the chapter “Installing the Router” and then power up the router.
Configuring the Router Step 2 Enter the config terminal command at the enable prompt to enter configuration mode: Router# config terminal You can now make changes to the configuration. Press Ctrl-Z to exit configuration mode.
Specifying the Boot Method Table 4-2 Half-Duplex Timer Commands (Continued) Timer Syntax Default Setting (Milliseconds) RTS timeout half-duplex timer rts-timeout 2000 Transmit delay half-duplex transmit-delay 0 Specifying the Boot Method You can enter multiple boot commands in the configuration in NVRAM to provide backup methods for loading the Cisco IOS image onto the router. The router boots using the first boot command that succeeds.

A P PEN D I X A Troubleshooting the Router This appendix contains information about how to isolate problems with the router and includes the following sections: • • Isolating Problems Reading the LEDs Isolating Problems The key to problem solving in this system is to try to isolate the problem to a specific subsystem. By comparing what the system is doing to what it should be doing, the task of isolating the problem is greatly simplified.
Isolating Problems Troubleshooting the Power and Cooling Systems Check the following items to help isolate the problem: • When the power switch is in the ON position (|) and the System OK LED is ON, are the fans operating? If not, check the fans. • Does the router shutdown after being ON a short time? Check the environmental conditions. The router might be overheating, resulting in a thermal-induced shutdown. Ensure that the chassis intake and exhaust vents are clear.
Reading the LEDs Reading the LEDs The LEDs indicate the current operating condition of the router. You can observe the LEDs, note any fault condition that the router is encountering, and then contact your system administrator or technical support, if necessary. For information about how to contact technical assistance, refer to the section “Obtaining Service and Support” in the chapter “Overview of the router.” Figure A-1 shows the location of the LEDs on the rear panel of the routers.

A P PEN D I X B Maintaining the Router This appendix contains selected maintenance procedures you might need to perform on the router as your internetworking needs change. This appendix includes the following sections: • • • • Opening the Chassis Upgrading the DRAM SIMM Replacing the System-Code SIMMs Closing the Chassis Additional maintenance procedures are available on the documentation CD that accompanied the router.
Opening the Chassis Opening the Chassis This section describes the procedure for opening the chassis by removing the chassis cover. Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is OFF and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.
Opening the Chassis Step 3 Turn the unit upside down so that the top of the chassis is resting on a flat surface, and the front of the chassis is facing toward you. (See Figure B-1, Part A.) Step 4 Remove the single screw located on the bottom of the chassis (on the side closest to you). Note that the chassis is comprised of two sections: top and bottom.
Opening the Chassis When the top cover is off, set it aside. Figure B-2 shows the layout of the system card, which is the same for the routers.
Upgrading the DRAM SIMM Upgrading the DRAM SIMM This section describes how to upgrade the DRAM SIMM on the system card. You might need to upgrade the DRAM SIMM for the following reasons: • • You upgrade the Cisco IOS feature set or release. Your router maintains large routing tables or other memory-intensive features, such as spoofing or protocol translations. To see how much memory is currently installed in the router, enter the show version command.
Upgrading the DRAM SIMM Step 4 Remove the existing DRAM SIMM by pulling outward on the connectors to unlatch them, as shown in Figure B-3. Be careful not to break the holders on the SIMM connector. Caution To prevent damage, do not press on the center of the SIMMs. Handle each SIMM carefully. Step 5 Position the new SIMM so that the polarization notch is located at the left end of the SIMM socket. (See Figure B-3.
Replacing the System-Code SIMMs Step 6 Insert the new DRAM SIMM by sliding the end with the metal fingers into the SIMM connector socket at approximately a 45-degree angle to the system card. Gently rock the SIMM back into place until the latch on either side snaps into place. Do not use excessive force because the connector may break. Step 7 Replace the router cover. Follow the instructions in the section “Closing the Chassis” later in this appendix.
