Not a good sign. Try swapping memory between the two boxes?
Try setting the config register with bit 8000 set (o/r 0xa101)
to get more diagnostics about what is hanging inside POST.
I've pasted the results from 0xa101 to the bottom of this message.
Everything appears to be ok to my inexperienced eyes.
I tried swapping the memory. The "dead" router booted up and got me
to a real command prompt, though it did spit out some errors. Mainly
stating that such and such is not support etc... Maybe a version
mismatch of some kind?
Is it possible I just have a dead flash memory simm? (just to
confirm, my 2501 has three pieces of replaceable memory, the pair is
the RAM right? And the single is the Flash?
You aren't getting far enough for password recovery. The 2501 ROMMON
doesn't support TFTP. It has a boot ROM and Flash ROM, so you could
always fall back to boot ROM to get something new TFTP'd into
FlashROM. But you are failing before any of this, you are trapped in
POST.
This is what I figured. Bummer.
Well, if you bought it from somebody, I'd do a return of it if they
offered it right away. If not, you may have a doorstop, as its not
getting past POST.- Hide quoted text -
Good advice, though for the $20 bucks this thing cost me it isn't
worth the trouble. Plus I feel I got a good deal on the other one,
and he tossed in some AUI converters, so I won't complain.
So should I try to find a new 16meg flash simm?

Thanks again,

i believe you will find that the single simm is the ram and the pair is
the flash memory.
