2500 Memory Upgrade (2)

I just upgraded the memory on two 2500 routers.

When one of the routers is bootstrapping, I get the message; "No usable interfaces", but the interfaces later appear to be recognized; "1 Ethernet/IEEE 802.3 interface. 2 Serial network interfaces.".

Then the router comes up with this prompt: "Router(boot)>" instead of "Router>".

The router appears to be recognising all the new memory, I have checked to make sure the memory is seated properly, and there are no other visible problems.

Did I do something wrong when upgrading the memory?

How do I get the router to boot to the normal prompt?

Many Thanks for your time!

Re: 2500 Memory Upgrade (2)

Hello,

your config register has probably changed to 0x2101 which tells the system to start in "boot" mode. You wont be able to see additional modules or run certain IOS function in this mode. If you do a "show version" it will tell you what the config-register setting is.

You'll have to change your config-register setting to 0x2102 so the router boots into normal startup mode.

Router(boot)>config t

Router(boot)>config-register 0x2102

Exit and reload the router (do a show version first to check the config-register has changed to 0x2102 for next reload). It should load the IOS from flash and your startup config from NVRAM.

Boot mode is usually use to re-install IOS. It may default to this mode when it can not find a good IOS image on your flash, so you may need to check (and reinstall) your IOS file if the router still does not load correctly.

Regards,

Georg
