[c-nsp] dead npe?

[Paul Cairney]

I recently took delivery of a refurb npe-300 (sold as "unpacked to check 
contents and carry out basic tests and has not been installed in a 
working environment.") however seems DOA.

Just want to check the symptoms to see if this is consistent with the 
diagnosis (never had a npe die yet) and see if anyone has any 
suggestions for other causes or things to try.

Hardware is 7204vxr,I have tried multiple c7200-io-fe's and flash disks, 
removing all the PA's and even swapping both banks of ram from the units 
current working npe-300. Obviously i have reseated everything i can 
think of, swapped between the good npe many times. Board seems fine 
physically, no cracks or damaged looking components,

Symptoms are the unit will power up, 'io power' led comes on however 
none of the interface led's light or anything on consol.

I tried deliberately badly seating the known good npe and the unit 
behaved like no npe was present (ie psu led flashes and the unit does 
not power on), dont want to repeat this as im worried initially powering 
on the unit with the new npe badly seated cold have caused this.

Aside from the chassis (only got one vxr), I have swapped every other 
component and am pretty resined to the conclusion it is DOA. Im just 
glad this was intended as a spare rather than replacement.

Anyone care to offer any suggestions about exactly what part of the npe 
has gone wrong, or is it worth attempting to re-seat it a few more times?

Regards,

Paul
