Router Fails to Boot

The Cisco 7500 series routers require that the first file on bootflash be a boot image. If it is not, the
bootstrap software attempts to boot whatever file is first. While attempting to boot a non-image file, the
system either crashes or hangs. The symptom for the RSP might be a series of Cs (CCCCC) displayed
on the console. To troubleshoot, install a Flash Disk with a bootable first image in slot 0 of the RSP to
allow the router to boot the Cisco IOS image. Verify the system boot settings using the show bootvar
command.

Note

If the configuration register is set incorrectly, this could lead to a boot failure. Refer to the

“Replacing

and Upgrading DRAM SIMMs” section on page 71

 for instructions on setting your configuration

register. Setting the config-register to 0x0 sets the boot variable to boot to ROMMON.

If your router continues to experiences this problem, open a case with TAC. See the

“Obtaining

Technical Assistance” section on page 86

 for more information.

Troubleshooting a Failed RSP2

When a new active RSP2 takes over ownership of the router, it automatically reboots the failed RSP2 as
the standby RSP2. You can access the state of the failed RSP2 in the form of a stack trace from the active
console using the show stacks command.

You can also manually reload a failed standby RSP2 from the active console. To do so, perform the
following task from global configuration mode:

Displaying Information About the Active and the Standby RSP2s

You can also display information about the active and the standby RSP2s. To do so, perform any of the
following tasks from EXEC mode:
