IOS image to big for 2610 router

aueddonline

hey guys, I loaded an IOs image from a TFTP server onto this router and am getting this when the router boots, My thinking is that the image is to large for the memory I have but I wasn't sure why it let me load the image and the checksum was fine if the router can't handle it?

You only have 24Mb ram, you dont have enough ram to run 12.3 ipbase.
Even most 12.2 images will not run on 24MB ram. Upgrade your ram to 64MB
and you'll be able to run any image for the 2610 if you have 16MB flash

When you boot the router it will show you how much installed memory the chassis has. Once you know that, get the router into rommon mode by doing the following:

http://www.cisco.com/warp/public/474/pswdrec_2600.shtml

Then type "dir flash:" to see the size of the installed images.

rommon 1 > dir flash:
File size Checksum File name
5358032 bytes (0x51c1d0) 0x7b16 c2600-i-mz.122-10b.bin
rommon 2 >

Odds are you either partially installed an image that's too large or it's corrupted. I'd install the old IOS just to get it back to stable then get a version of IOS that your router can support. Follow the "Using TFTP to download IOS to the router" link near the bottom of the page which I linked you to for instructions on how to delete the installed IOS image and install a new one. Use TFTP if possible, it's pretty fast and painless.

hey thanks for the link i'll have to get a suitible IOS off another router I got stored

congrats on the ISCW pass by the way paul

rommon 1 > dir flash:
File size Checksum File name
7767428 bytes (0x768584) 0xab56 flsah
rommon 2 > rename flsah flash:


hey what's with the spelling of flash?

You may have done a "copy tftp flsah" and it copied the file to a file named "flsah". I have that problem with students who use "copy tftp running-configuration" then end up erasing the fpash on the rotuer.

aueddonline

is there a way to rename that?

dtlokee

rename flash:/falsh flash:/<whatever name you want>

aueddonline

rommon 10 > rename flash:/flsah flash:/flash:c2600-12.3.bin

monitor: command "rename" not found




I used that command the other day one switch, this routers not buying it though

If you have a TFTP server handy you can still boot larger images of TFTP. I often run 12.3 2600 XM images on my non XM 2600's so i can play with IPv6. Instructions can be found here:

Give it a shot and let me know if you have any problems, i'm happy to help!

I didn't notice you were in rommon, you can use the tftpdnld command to reload an image.

His issue is that there is not enough RAM in the router to boot the image (only 24mb) so booting from a TFTP server isn't going to allow him to run the larger image.

hey thanks for the doc, they are petty good the cisco docs I wasn't a fan to start with mainly because they were a bit like information overload but i'm being turned.


I managed to put an older image on 12.0-4(T) something like that, I remember having to do this before when I enterered the command 'erase flash' when I was doing the CCNA

does anyone use the "show file systems" command?

i like that one, its easier for me to read for some reason.

Paul Boz

If it's a larger chassis with multiple memory sources I use it.

darkuser

max out your ram/flash .....

and that expert advise comes without reading any of the previous thread .....
