Re: Cisco 1841 Failed after resetting to factory defaults

intrusdave · ‎05-23-2013

I could really use help on this. I have an 1841 (256M w/ crypto card) that stopped booting.

I reset it to factory defaults as per Cisco's directions, then began to setup with Cisco Configuration Professional.

On the next reload I get this:

program load complete, entry point: 0x8000f000, size: 0xcb80

program load complete, entry point: 0x8000f000, size: 0x2a0b48c

Self decompressing the image : ########################################################################################################################################################################################################################################################## [OK]

Wrong system software for this hardware

System Bootstrap, Version 12.4(13r)T, RELEASE SOFTWARE (fc1)

Technical Support: http://www.cisco.com/techsupport

PLD version 0x10

GIO ASIC version 0x127

c1841 platform with 262144 Kbytes of main memory

Main memory is configured to 64 bit mode with parity disabled

Readonly ROMMON initialized

rommon 1 >

The ios on the flash is "c1841-advsecurityk9-mz.124-22.T.bin"

Can someone please tell me what I'm doing wrong?

Thank You

Is it possible that someone changed the flash card or the image on the flash card? what does dir indicate?

As a way to get around the immediate problem is it feasible to use tftpdnld in rommon to download an image from a tftp server? Once you get the router up and running you can then investigate the status of flash and the content of flash.

Hello,

if you've not erased or formated the hole flash you could try this:

flash_init

boot

Kind regards

Thanks Guys.

I'm not sure what has happened. I do know that the cookie was corrupt, which I have fixed. (Not a fun process). I don't understand why the router would boot with 15.1 and then suddenly stop with the wrong software error. I had it running on

c1841-advipservicesk9-mz.151-4.M.bin for several days before this happened.

I have it running c1841-ipbasek9-mz.124-25a.bin right now, though it is currently at factory defaults.

Kai - the flash_init... Can you explain what this does and what I would need to do from that point?

Thank You Again for the help.

Hello,

flash_init will initialize the flash, whick is not loaded, when you are on rommon. After you have initialized the flash you could try by using the command 'boot' to load the IOS, which should be on the flash.

If this will fail, you have to copy a new IOS to the flash, this I can explain to you later.

If you've successfully boot the swich, it will may be run an old configuration or will ask you to run the setup wizzard. Answer the question with no, than a prompt like Router> will apear. Now enter 'enable' and you will enter the enable mode and the prompt will change to Router#.

Now enter show flash: and you will see the content for the flash: e.g.

...

c1841-ipbasek9-mz.124-25a.bin

...

after you found the IOS on the flash, you must enter the configuration mode 'configure terminal'. Here you set the command to boot the correct IOS

boot system flash:c1841-ipbasek9-mz.124-25a.bin

Now leave the configuration mode by using 'exit' after this save the configuration 'wirte memory' and reload the device. Now the Router should boot normally.

Kind regards

Kai
