problem installing new IOS Image

opiedrah

Level 1

I bought a new 2500 router from ebay, however it currently doesn't have an IOS image loaded, i setup a TFTP server and downloaded a 12.1 Ios Image, however i have not been able to upload it to the routers flash. here is the output

Router(boot)#copy tftp flash

System flash directory:

No files in System flash

[0 bytes used, 16777216 available, 16777216 total]

Address or name of remote host [192.168.1.105]? 192.168.1.105

Source file name? c2500-ios56i-l.121-20.bin

Destination file name [c2500-ios56i-l.121-20.bin]?

Accessing file 'c2500-ios56i-l.121-20.bin' on 192.168.1.105...

Loading c2500-ios56i-l.121-20.bin from 192.168.1.105 (via Ethernet0): ! [OK]

--- THIS IS THE PART THAT MESSES ME UP --------

Device needs erasure before copying new file

Erase flash device before writing? [confirm]

Copy 'c2500-ios56i-l.121-20.bin' from server

as 'c2500-ios56i-l.121-20.bin' into Flash WITH erase? [yes/no]y

Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee ...NOT erased

Copy aborted - erase failed

ERR: 'c2500-ios56i-l.121-20.bin' open - device needs erasure

Router(boot)#

Router(boot)>sh flash

System flash directory:

No files in System flash

[0 bytes used, 16777216 available, 16777216 total]

16384K bytes of processor board System flash (Read/Write)

If i try to boot from an Ftp server like

boot system tftp <ios img> <tftp IP>

it still the same thing, i get brought back to

Router(boot)>

This is driving me nuts, its suppose to be something simple.

Thanks

Have you tried erasing the flash manually (erase flash)

Also you could try loading the IOS without erasing the flash (type NO at Flash WITH erase? [yes/no]y)

If both these fail try reseating the flash SIM's, they may be slightly loose. If not one of the flash SIM may be faulty, try removing one at a time and then erasing the other one, this should identify which chip is faulty.

Hope this helps.

Your output shows 0 files on flash, ie your flash memory has no IOS files. You cannot do any tftp now.

The only thing you can do is to manually upload the IOS into your flash using "x-modem" from hyperterminal.

http://www.cisco.com/warp/public/130/xmodem_generic.html#download_2620

have a look at this URL and let us know in case of any queries.

When i enter config-reg 0x0 i do not get to ROMmon mode, i only see a

prompt

there are no xmodem commands available.

The server in question is a 2501

Any advice is appricieated.
