Problem resetting RMA'ed 4451-X

[Brian Green]

Hi,

I am trying to factory reset a 4451-X Router to the default configuration.  We've customized the config, but now when it reboots it reports a bunch of bootflash errors, then reboots again.  Is there any way we can reset this thing?  I can access the rommon mode by issuing a break on initial boot, but that's the only prompt I can get to.

Thanks!

Hello bwgreen99,

Once in Rommon, change the config reg to ignore startup.

(configuration register bit 6 (0x0040) so that the startup configuration (usually in NVRAM) is ignored.)

Once router is back up, copy startup into running config.

Hopefully this will get you back up.

Look in the logs for a clue to why it was rebooting.

What were your bootflash errors?

Hope this helps,

Please rate helpful posts.

Thanks.

Thanks - I was able to get into it and get it ready to go back!
