Can't send break for PW recovery -- 2500's

Mar 27, 2008 4 Replies

We've got hold of a few old dinosaurs that will still be useful to us, some 2500's, some 4500's and a 2621. I've been able to send a break and go through the PW recovery sequence easily with some of them, but a two of them -- specially a 2514 I'm working with right now -- just won't see a break signal from TeraTerm, Hyperterm or half a dozen emulators from TuCows. Is there a physical way to get it to boot to rommon, jumper or short-across, something like that?



Thanks in advance,


Bob W.


Not saying this is your answer, but when you're stuck, it rarely hurts to read another document.

The following document can be found on the Cisco web site:

Thanks, News Reader. I did go get that list of break sequences, I'd forgotten they were there. But with both the 2514 and the 4500 I'm getting SOME response but not the right one. Here's what it looks like

..... and then it goes ahead with a normal boot

Thats not what the document says to do for a 2500? They are old schoool.

Read this link.

Thanks Doug. That was exactly what I needed. When it didn't say rommon> I thought it hadn't responded to the break. > o/r 0x2141 got me right in. Appreciate the quick help.
