Duff 2600?

[lee]

Hi Guys,

I hope I explain this properly.

We currently have a install from one site to another, we are only concerned with the first site which has a pair of EARLY 2610XM's (that only came with 32mb of ram instead of 128mb).

The lines were upgraded to E1 so we bought E1 cards for each router, once we installed these we soon realised that they werent being picked up due to running 12.2 IOS.

We did a code upgrade on both routers to 12.3 1a which the first router took fine and detected the E1 card, however the second router decided not to boot the new code (it was displaying an error message regarding a lack of memory) and went back to its previous 12.2 code. We decided from the error message that the secondary router must of had a few bad blocks of RAM causing it not to boot.

We believed this to be a memory issue at first so we upgraded both to 128mb of RAM, both routers took the RAM without an issue but still the secondary router decided not to boot the new 12.3 code, this time it got as far as decompressing the image then crashdumped a few times before booting the other 12.2 code.

I'm back where I started now and I'm unsure where to look next.

Both E1 cards came from the same supplier

Both sticks of 128mb RAM came from the same supplier.

Cheers.

Hi

First of all we have to make sure that the cards are working properly, for which try swapping the cards between both the routers,if the problem persists in the same router then we have to check other things.If the first router dosn't work then there is prob. in the card.

Second,if in case the cards are ok then try booting the router using TFTP server, which will eliminate flash, which may be the source of trouble.

Third,try swapping the RAM.

If still prob. persists then there is problem with the NM slot of the router.

Hi,

Seems like a good path to follow with trouble-shooting this router. I'll use a FTP server instead of TFTP as I havent been having the best of luck with TFTP these days.

If I do find out its the flash thats the source of the trouble, how would I go about replacing that? When doing the memory upgrade the other night I noted that the flash wasnt modulated, its hard wired onto the board but there is a spare flash slot... I'm guessing I would have to plug it in there and use flash1: ?

Also if the problem still persists (pointing to the slot) I take it I will have to replace the router?

Thank you for your help.

Hi

Glad you had appreciated my concept.

I have not mentioned that the flash is faulty.I am only saying that it may not meet the requirement.

If the router are of same hardware configuration then its definately the prob. of NM slot.You will have to repair that as far as I know.

Try doing it.

Hi there,

just thought i would post a follow up, the first thing we did was try to boot the 12.3 code without the E1 card and found that it booted perfectly, we need swapped over the cards between the 2600's and found they both booted perfectly.

Little disapointed that we havent been able to get a real cause of the problem, but everything is working fine now.
