[j-nsp] IQ2 PIC won't stay online

Hello List,

 

I've an IQ2 PIC (PE-4GE-TYPE1-SFP-IQ2) in an M7i that won't come online
for some reason. Or, rather, it seems to come online, stay on for
approximately 3 minutes, then resets, comes back online. It does this
last four times and then stays offline until the next time I run
'request pic online ...'.

 

Even when the PIC is showing as online, none of the inserted SFPs are
detected. I've inserted the PIC into the spare slot in an M10i, where it
came online - and stayed online - without problem so I'm certain that
the PIC itself is fine. My next step is obviously to try a different PIC
in the M7i to see if the slot itself is shagged.

 

Before I do that though, is there anything else I can check on the M7i?
I've looked in the chassisd log and there's nothing in there that would
indicate what the problem is:

The M7i is fully-loaded (i.e., PE-1GE-SFP in every other port); it has
an RE-400-256-S (with 512MB RAM) and a built-in 1GE port.

 

I'm probably looking at a knackered slot here but any suggestions or
pointers would be appreciated.

 

Thanks in advance,
