A P P E N D I X A Troubleshooting Your Cisco 2600 series router goes through extensive testing and burn-in before leaving the factory. If you encounter problems, use the information in this appendix to help isolate problems or to eliminate the router as the source of the problem.
Appendix A Troubleshooting Isolating Problems • Modules—LEDs on the modules can help identify a failure. • Cables—External cables that connect the router to the network. Troubleshooting the Power and Cooling Systems Both the system LED and the fans can help you troubleshoot a power problem. Check the following items to help isolate the problem: • With the power switch on, does the system LED stay on or blink? – If the LED is green, the router is receiving power and is functional.
Appendix A Troubleshooting Isolating Problems Troubleshooting Modules, Cables, and Connections Network problems can be caused by a module; cables or cable connections; or external devices such as a modem, transceiver, hub, wall jack, WAN interface, or terminal. Check for the following symptoms to help isolate the problem: Tip All the documents mentioned in this section are available both on the Documentation CD-ROM and online. • Module is not recognized by the router.
Appendix A Troubleshooting System Messages System Messages This section describes system error and recovery messages that may appear when operating a Cisco 2600 series router. Error messages for Cisco 2600 series routers powered by the Cisco redundant power system are described in the publication Cisco RPS Installation Guide. The Cisco IOS software displays system error and recovery messages on an external device console terminal screen.
A P P E N D I X B Using the ROM Monitor This appendix describes the use of the ROM monitor (also called the bootstrap program), which is the firmware that runs when you power up or restart a Cisco router. During normal operation, the ROM monitor helps to initialize the processor hardware and boot the operating system software. You can also use the ROM monitor to: • Help isolate hardware problems encountered when installing your router.
Appendix B Using the ROM Monitor ROM Monitor Commands As long as the configuration register value remains 0x0, you must manually boot the operating system from the console. Refer to the boot command in the “ROM Monitor Command Descriptions” section on page B-4. The two methods of entering the ROM monitor mode are as follows: Enter ROM Monitor Mode by Using the reload Command Connect to the router from a console, and follow these steps: Step 1 Restart the router with the reload command.

Appendix B Using the ROM Monitor ROM Monitor Command Descriptions ROM Monitor Command Descriptions Router Management Commands This section lists some useful ROM monitor commands. Refer to the Cisco IOS configuration guides and command references for more information on ROM monitor commands. Boot Commands in the ROM Monitor Functions of Boot Commands The router always boots first from a Cisco IOS image in flash memory, because there is no separate, dedicated boothelper image ([rx]boot).
Appendix B Using the ROM Monitor ROM Monitor Command Descriptions • boot—Boots from the first Cisco IOS image in internal flash memory. • boot flash:—Boots from the first Cisco IOS image in the internal Flash memory. • boot flash: partition:—Boots from the first Cisco IOS image in the specified partition in internal flash memory. • boot flash: filename—Boots from the Cisco specified IOS image in internal flash memory.
Appendix B Using the ROM Monitor ROM Monitor Command Descriptions meminfo [-l]—The meminfo command with the -l option shows supported DRAM configurations.
Appendix B Using the ROM Monitor ROM Monitor Command Descriptions • sysret—Views return information from the last booted system image. This information includes the reason for terminating the image, a stack dump of up to eight frames, and, if an exception is involved, the address where the exception occurred.

Appendix B Using the ROM Monitor Recovering Cisco IOS Software Images Note The tftpdnld command is not available on the Cisco 2691 router. The recommended method for installing a Cisco IOS image on a Cisco 2691 router is from a CompactFlash memory card loaded in the external CompactFlash memory card slot. See the “Entering Boot Commands” procedure on page B-4.
Appendix B Using the ROM Monitor Recovering Cisco IOS Software Images Step 3 Enter the xmodem command and the name of the source file containing the Cisco IOS image: rommon 1> xmodem filename When the source file is found, messages similar to the following appear: Do not start upload program yet... File size Checksum File name 2537948 bytes (0x26b9dc) c2600-i-mz.122-10.bin WARN: This operation will ERASE bootflash.
Appendix B Using the ROM Monitor Recovering Cisco IOS Software Images Procedure for the tftpdnld Command Step 1 Specify the required variables, for example: rommon rommon rommon rommon rommon 1> 2> 3> 4> 5> IP_ADDRESS=172.15.19.11 IP_SUBNET_MASK=255.255.255.0 DEFAULT_GATEWAY=172.16.19.1 TFTP_SERVER=172.15.20.
Appendix B Using the ROM Monitor Recovering Cisco IOS Software Images Specify the TR_SPEED_MODE variable only for routers with a Token Ring network interface; or for routers with both an Ethernet and a Token Ring port, those routers that are set to use the Token Ring port with the tftpdnld command. Note • TR_1E1R_PORT—Sets the port to be used with the tftpdnld command. 0=Use Ethernet port; 1=Use Token Ring port. The default is 0.
