Unfortunately, I don't know any way of determining the cause of a hardware
problem in a 2500 other than to swap out the components and see what
happens. If I am not mistaken, the modules in the 2500 are just SIMMS, so if
you have a spare one lying around, you could just swap them out. Otherwise,
if you have a Smartnet contract (or you bought the router new and have not
yet called support), you can call Cisco and they can help you get it
repaired or replaced.
