Level 1

Hi,

I have a Cisco 1801 System Bootstrap ver 12.3 which does not want to come out ROMMON mode.

I tried a few different things with 'reset' and all. Any hope ?

Thanks,

Ashok

I think the flash of the device is corrupted. Can you please try inserting a new flash into device see if the new flash get recognized?

Console into the appliance and reboot.  Post the entire boot-up process.

Hi Leo,

This is what I get when power up.

Thanks,

Ashok

Hi,

Do you have the IOS copied into the flash of the device?

boot: cannot open "flash:"
boot: cannot determine first file name on device "flash:"

Seems like the device can't locate the file in the flash. Can you try dir flash command?

Hi CF,

It gives the following response:

Thanks, Ashok

____________________________

rommon 1 > dir flash
bad device name
usage: dir <device>
rommon 2 >

actually I ran again with : at the end i.e. 'dir flash:' and it gave me back:

_______________________

'dir: cannot open device "flash"

____________________________

then I ran dev' it gives:

Devices in device table:

   id     name

flash:   external compact flash

bootflash: boot flash

Any hope to make use of this router, from scratch?

Thanks CF,

Will try to find and would update.

Thanks,

Hi CF,

I did find another one and this one is recognized and I able to go in and start configuring it.You all have been so helpful and have a glass or two of Chardonnay on me.

Thanks,

Ashok

I see there are a lot of ROMMOM commands available for 1800 series - http://www.cisco.com/c/en/us/td/docs/routers/access/1800/1801/software/configuration/guide/scg/rommon.html

If "fsck" cannot find or fix the filesystem I would take the out the flash and try to low-level format it on a PC, format it again on the router and copy an IOS image on it.  If any of these fails then it probably needs to be replaced...

Thanks Lulian,

Yes this is really helpful. Appreciate the info.

Thanks,

Ashok

The "bad device name" error is most likely because "dir flash:" should be used (notice the colon at the end)...

boot: cannot determine first file name on device "flash:"

Means there is no valid IOS filename in the CF.  

System Bootstrap, Version 12.3(8r)YH8, RELEASE SOFTWARE (fc2)

Bootstrap is default so this means the IOS can't be read from a USB thumb-drive and the only way to boot the IOS is XModem or copy the correct IOS file into the CF and boot.

Hi Leo,

I will check on how to do the xmodem or copy an IOS into CF

Thanks,

Ashok
