General Site Requirements 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 routers can be placed on a desktop or mounted in a rack or on a wall. The location of the routers and the layout of your equipment rack or wiring room are extremely important for proper system operation.
General Site Requirements Configuring Equipment Racks The following tips will help you plan an acceptable equipment rack configuration: • Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. • When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust ports.
Installation Checklist The router’s AC power supply includes the following features: • • Autoselects either 110V or 220V operation. All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation for the unit.) Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.

Table 2-6 lists the standard relationship between baud rate and maximum distance for EIA/TIA-449 signals. These limits are also valid for V.
Preparing to Connect to a Network Ethernet Connections On the Cisco 2524 router, there are two Ethernet ports, an AUI port and a 10BaseT port, on the rear panel of the router. To connect your router to an Ethernet network, you can use either the Ethernet AUI or 10BaseT port, but not both. The router automatically detects which port is in use. (If you attempt to use both ports, only the 10BaseT port will work.
Preparing to Connect to a Network The main difference between the console and auxiliary ports is that the auxiliary port supports 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. The router, cables, UniverCD or printed publications, and any optional equipment you ordered might be shipped in more than one container.

4 CHAPT E R Configuring the Cisco 2524 and Cisco 2525 Routers This chapter describes how to configure the Cisco 2524 and Cisco 2525 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 just enough information to get the router up and running. For Cisco IOS Release 11.
Configuring the Router 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. 5 If a valid configuration file is not found in NVRAM, the router runs the System Configuration Dialog so you can configure it manually.
Configuring the Router Using Configuration Mode You can configure the router manually if you prefer not to use AutoInstall or the System Configuration Dialog. Take the following steps to configure the router manually: Step 1 Connect a console terminal following the instructions in the section “Connecting the Console Terminal and Modem” in the chapter “Installing the Cisco 2524 and Cisco 2525 Routers,” and then power ON the router.
Configuring the Router The results of the show running-config and show startup-config commands will be different if you have made changes to the configuration but have not yet written them to NVRAM. To make your changes permanent, enter the copy running-config startup-config command at the enable prompt: Router# copy running-config startup-config ******** The router is now configured and will boot with the configuration you entered.
Configuring the Router Take the following steps to prepare your router for the AutoInstall process: Step 1 Attach the WAN cable to the router. Step 2 Turn ON power to the router. The router will load the operating system image from Flash memory. If the remote end of the WAN connection is connected and properly configured, the AutoInstall process will begin. If AutoInstall successfully completes, you can write the configuration data to the router’s NVRAM. Perform the following step to complete this task.
Configuring the Router At any time during the System Configuration Dialog, you can request help by typing a question mark (?) at a prompt. Before proceeding with the System Configuration Dialog, obtain from your system administrator the node addresses and the number of bits in the subnet field (if applicable) of the Ethernet and synchronous serial ports. For more information about Internet Protocol (IP) addresses and subnets, refer to the publication Internetworking Technology Overview.
Configuring the Router Restricted Rights Legend Use, duplication, or disclosure by the Government is subject to restrictions as set forth in subparagraph (c) of the Commercial Computer Software - Restricted Rights clause at FAR sec. 52.227-19 and subparagraph (c) (1) (ii) of the Rights in Technical Data and Computer Software clause at DFARS sec. 252.227-7013.

Specifying the Boot Method Specifying the Boot Method You can enter multiple boot commands in the configuration in NVRAM to provide a backup method for loading the Cisco IOS image onto the router. The router boots using the first boot command that succeeds. If you enter multiple boot commands, the router executes them in the order they are entered. There are two ways to load the Cisco IOS image: from Flash memory or from a TFTP server on the network.

A APPEND IX Maintaining the Cisco 2524 and Cisco 2525 Routers This appendix contains information about maintenance procedures you might need to perform on the router as your internetworking needs change.
Installing WAN Modules Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. (To see translated versions of this warning, refer to the appendix “Translated Safety Warnings.”) Installing WAN Modules You can install WAN modules in the router without removing the chassis cover. Each router chassis can accommodate up to three WAN modules—two synchronous serial and one ISDN.
Opening the Chassis Step 4 Tighten the two captive screws on the module to secure it to the chassis. Caution Although there are three slots available for the WAN modules, the slot on the far right (labeled BRI 0) is reserved for an ISDN WAN module only. Install all other modules in the slots labeled SERIAL 0 and SERIAL 1. The ISDN WAN modules are designed so that you cannot insert them into the synchronous serial slots.
Opening the Chassis Tools Required You will need the following tools to open the chassis: • • Medium-size flat-blade screwdriver (1/4 inch [0.625 cm]) Size M 3.5 (metric) hex-head nut driver (optional) Removing the Chassis Cover You must open the router chassis to gain access to its interior components: the system card, system-code single in-line memory modules (SIMMs), and DRAM SIMMs. When opening the chassis, refer to Parts A and B in Figure A-2.
Opening the Chassis Figure A-2 Chassis Cover Removal A Flat-blade screwdriver H3556 SERIES Slot Screw Slot B H3557 Top section Bottom section Rear Left end toward you Front 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.
Upgrading the Boot Flash Memory Step 8 When the top cover is off, set it aside. Figure A-3 shows the layout of the system card, which is attached to the bottom section of the chassis.
Upgrading the DRAM SIMM Step 4 Insert the Flash memory card into the Personal Computer Memory Card International Association (PCMCIA) slot. Step 5 Turn ON power to the router. The system copies the boot image on the Flash memory card to the boot Flash memory on the system card: Cisco Systems Diagnostic Monitor Testing boot state Exiting boot state Testing Main Memory from 0h to C000h. data equals address Testing Main Memory from 0h to C000h. checkerboard Testing Main Memory from 0h to C000h.
Upgrading the DRAM SIMM Cisco IOS feature set requires a DRAM configuration other than 4, 8, or 16 MB, your router will have a combination of fixed DRAM and a DRAM SIMM. For example, if the Cisco IOS feature set originally ordered with your router requires 6-MB DRAM, your router will include 2-MB fixed DRAM and a 4-MB DRAM SIMM for a total of 6-MB DRAM (because a 6-MB DRAM SIMM is not available).
Upgrading the DRAM SIMM This line shows how much memory is installed (in this example, 4092K/2048K). The first number represents primary memory and the second number represents shared memory. Tools and Equipment Required You will need the following tools to remove and replace the DRAM SIMM on the router: • • • Medium-size flat-blade screwdriver (1/4 inch [0.
Upgrading the DRAM SIMM Figure A-4 Removing and Replacing the DRAM SIMM Pull the tabs away with your thumbs, bracing your forefingers against the posts. Raise the SIMM to a vertical position. Connector edge of the system card Polarization notch H3558 DRAM SIMM card Step 6 Using the system card orientation shown in Figure A-4, position the new SIMM so that the polarization notch is located at the right end of the SIMM socket.
Replacing System-Code SIMMs Replacing System-Code SIMMs The system code (software) is stored in Flash memory SIMMs. The 80-pin Flash memory SIMMs must be purchased from Cisco Systems. Contact a customer service representative for more information. Note The system code for both the Cisco 2524 and Cisco 2525 can be contained on either one or two 80-pin Flash memory SIMMs. If only one 80-pin SIMM socket is populated, it must be the SIMM socket indicated in Figure A-3 (labeled CODE0).
Replacing System-Code SIMMs Step 6 Remove the existing system-code SIMM by pulling outward on the connector holders to unlatch them. The connector holds the SIMM tightly, so be careful not to break the holders on the SIMM connector. (See Figure A-5.) Caution To prevent damage, do not press on the center of the SIMMs. Handle each SIMM carefully. Step 7 Repeat these steps for all the system-code SIMMs to be replaced.
Closing the Chassis Caution To prevent damage, note that some Flash memory SIMMs have the components mounted on the rear side; therefore, when inserting the SIMM, always use the polarization notch as a reference and not the position of the components on the SIMM. Step 9 Insert the new SIMM by sliding the end with the metal fingers into the appropriate SIMM connector socket (labeled CODE0 or CODE1 in Figure A-3) at approximately a 45-degree angle to the system card.
Closing the Chassis Replacing the Cover After you perform the maintenance for your system, perform the following steps to replace the cover: Step 1 Position the two chassis sections, as shown in Figure A-6. Step 2 Referring to Figure A-6, press the two chassis sections together and ensure the following: • • • The top section fits into the rear of the bottom section. (See A in Figure A-6.) The bottom section fits into the front of the top section. (See B in Figure A-6.
Recovering Lost Passwords Step 5 Reinstall the chassis on the wall, rack, desktop, or table. Step 6 Replace all cables. Recovering Lost Passwords This section explains how to recover the following types of passwords: • An enable secret password (a very secure, encrypted password). The enable secret password is available on routers running Cisco IOS Release 10.3(2) or later. • An enable password (a less secure, nonencrypted password).
Recovering Lost Passwords Step 4 If the configuration register is set to disable Break, power cycle the router. (Turn the router OFF, wait five seconds, and then turn the router ON again.) If the configuration register is set to enable Break, press the Break key or send a Break signal to the router and then proceed to Step 6. Note If your keyboard does not have a Break key, refer to your terminal or terminal emulation software documentation for information about how to send a Break signal to the router.
Recovering Lost Passwords Step 11 Scan the configuration file displayed for the passwords (the enable and enable secret passwords are usually near the beginning of the file and the console password is near the end of the file). An example display follows: enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei enable password sand . . line con 0 password seashells Proceed to Step 12 to replace an enable secret, console, or enable password.
Recovering Lost Passwords You can remove individual passwords by using the no form of these commands. For example, enter the no enable secret command to remove the enable secret password. Step 15 Configure all interfaces to be administratively up. In the following example, the Ethernet 0 port is configured to be administratively up: Router(config-line)# interface ethernet 0 Router(config-if)# no shutdown Enter the equivalent commands for all interfaces that were originally configured.
Virtual Configuration Register Settings Step 20 Press Return to confirm. When the router reboots it will use the new configuration register value you set in Step 16. Step 21 Log in to the router with the new or recovered passwords. Virtual Configuration Register Settings The router has a 16-bit virtual configuration register, which is written into NVRAM.
Virtual Configuration Register Settings Table A-2 Virtual Configuration Register Bit Meanings Bit No.
Virtual Configuration Register Settings Step 3 To set the contents of the configuration register, enter the configuration command config-register value, where value is a hexadecimal number preceded by 0x (see Table A-2 and Table A-3): config-register 0xvalue (The virtual configuration register is stored in NVRAM.) Table A-3 Explanation of Boot Field (Configuration Register Bits 00 to 03) Boot Field Boot Process 0x0 Stops the boot process in the ROM monitor.
Virtual Configuration Register Settings Virtual Configuration Register Bit Meanings The lowest four bits of the virtual configuration register (bits 3, 2, 1, and 0) form the boot field. (See Table A-3.) The boot field specifies a number in binary form.
Virtual Configuration Register Settings Action or Filename Bit 3 Bit 2 Bit 1 Bit 0 cisco6-igs 0 1 1 0 cisco7-igs 0 1 1 1 cisco10-igs 1 0 0 0 cisco11-igs 1 0 0 1 cisco12-igs 1 0 1 0 cisco13-igs 1 0 1 1 cisco14-igs 1 1 0 0 cisco15-igs 1 1 0 1 cisco16-igs 1 1 1 0 cisco17-igs 1 1 1 1 In the following example, the virtual configuration register is set to boot the router from Flash memory and to ignore Break at the next reboot of the router: router> enable p
Virtual Configuration Register Settings Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore the console Break key. Clearing bit 8 causes the processor to interpret the Break key as a command to force the system into the bootstrap monitor, thereby halting normal operation. A break can be sent in the first 60 seconds while the system reboots, regardless of the configuration settings. Bit 10 controls the host portion of the IP broadcast address.
Copying a Cisco IOS Image to Flash Memory Bit 13 determines the server response to a bootload failure. Setting bit 13 causes the server to load operating software from ROM after five unsuccessful attempts to load a boot file from the network. Clearing bit 13 causes the server to continue attempting to load a boot file from the network indefinitely. By factory default, bit 13 is set to 1.
Copying a Cisco IOS Image to Flash Memory The following messages display: **** NOTICE **** Flash load helper v1.0 This process will accept the copy options and then terminate the current system image to use the ROM based image for the copy. Routing functionality will not be available during that time. If you are logged in via telnet, this connection will terminate. Users with console access can see the results of the copy operation. ---- ******** ---Proceed? [confirm] Step 4 Press Return to confirm.
Copying a Cisco IOS Image to Flash Memory Step 9 Enter yes to confirm that you want to erase the contents of Flash memory. Messages similar to the following display: %SYS-5-RELOAD: Reload requested %FLH: master/igs-j-l.110-4.2 from 172.16.72.1 to flash ...
