Need help updating Cisco IOS on 1700 (Not enough space on device)

DJMK4 · 14 Feb 2011 at 20:12

I am trying to update the firmware on my 1700 series router as we have recently had an issue in work with connections going from 20CN to 21CN connections, and obviously the Cisco's are playing up, we have been uploading it to our customers Cisco boxes fine, seems have resolved the issues.

That got me thinking, at home I only use my 1700 for internal LAN routing, however if this IOS sorts out the issue with ADSL WIC's and 21CN, I am wondering if I can get this working on my BE connection at home (as before the issue was that ADSL WIC's didnt like ADSL2+ or 21CN connections and you had to buy H-WIC's).

However I have run in to a problem, after I backed up my config, I tried to update my IOS with this file I got from work, and I keep getting the following even though I have erased flash memory. Basically saying that there is not enough space.

This particular Cisco 1720 does not have an expansion slot for more memory to slot in, unless you can buy an adaptor and use one of the slots that the wic's go in to?

I have also tried squeezing the flash file system

The file is 14mb, however the flash memory is about 8mb

morandarouter1#dir flash:
Directory of flash:/

No files in directory

8126460 bytes total (8126460 bytes free)

When you download the IOS it should say required flash size. Could you do a "show ver" and show the output.

Some lower models dont have the required space to upgrade.

I would have said from that, you don't have enough Flash, without checking its going to be hard to find a 12.4 version that will fit in 8Mb...

Is there no way of upgrading the flash memory in these routers?

The model I have is a Cisco 1720, I may be able to swap it with a Cisco 1721, I think these have slightly larger flash memory.

It would appear that you can upgrade the flash in a 1700 series desktop chassis.

Cool thanks for the info, i'll keep this in mind, however for now I have swapped it with a 1721 which apparently has 32mb of flash.

Enough to stick my new IOS on

Will be updating the IOS at home later, I do have a question though, does uploading and flashing the unit with a new IOS cause it to peform a factory reset of the unit? reason I ask is because my server at home died, and I dont have any other machine with a serial connection.

So what I have had to do is do a factory reset on this Cisco, and do a basic config, enabling the FastEthernet0 port and enabling telnet so I can get on to the unit, however if it does a factory reset, this will wipe this, and the only way id be able to get on would be via console (useless when I dont have a serial port spare).

I need to get a usb console cable really however that is not an option today.

No it doesn't, assuming you don't wipe the flash. However the config may break if commands are different between IOS revisions.

DJMK4 · 15 Feb 2011 at 11:34

No worries, im going to update the IOS in work now on our config server. Get the worst of it out the way, then take it home later.
