[c-nsp] Line card faulty?

[Daniel Baumann]

Hello,
I'm using a 4506 as my core switch. This morning I noticed an issue with my line card 3:

Switch#sh module
Chassis Type : WS-C4506

Power consumed by backplane : 0 Watts

Mod Ports Card Type                              Model              Serial No.

None of the network devices attached to this line card seem to be affected in any way (yet?).
How would I go about finding out what's wrong with it? Should I start looking for a replacement?

Thanks,
