Cisco 1721 Problem

Joshua.M.Levine · ‎04-08-2005

I am having an issue with a Cisco 1721 router. I recently obtained this through unit supply and we have been having a problem with the router staying up and running. The router reboots repeatedly and indefinitely unless left unplugged for 20 minutes after being up for only a short while. The system displays, via a hyperterm window, the system bootstrap message and repeats it for an indefinite period. Any ideas what it could be?

Could be a corrupt IOS image on flash file, or no file at all in flash. Either ways, paste the output on the screen and we can help you from there.

System Bootstrap, Verison 12.2(7r)XM2 Release Software

TAC Support: HTTP://www.cisco.com/tac

This is the message that is repeated indefinitely after the router reboots itself after being on for a few minutes.

After powering the router off (once the continuous reboot cycle starts), it displays this message and then halts, I cant get any keystrokes sent to it, nor can I do anything with the router. The following lights remain lit once a reboot is performed

Power

OK

WIC0

WIC1

ACT/CH1

Any ideas?
