[j-nsp] fpc6 GE(6/3): Kchip 0 crc/fifo errors

[peter brenner]

Hello,

today we got the following error on one of our M160 routers on a GigE 
interface on
an otherwise unused fpc1.
We are running JunOS 7.6R1.10.

Taking PIC 3 in FPC 6 offline: Offlined by cli command

And since then the log is quiet again.

Both the fpc and the pic have never been used by us so I'm not sure where to 
place the blame. Can anyone point me to the right direction which fru to 
replace?

The following happened during the initial insertion of the frus:
