[c-nsp] 4GE-SFP-LC (4-Port ISE GigE) Failure rate

[Pete Kruckenberg]

Since I deployed 18 GSRs with the 4-port ISE GigE line-card
about 4 months ago, I've had 3 line-cards go bad, each for
something different (all hardware-related, usually something
related to bad memory).

None of these were DOA, they all worked for at least a few
weeks and started having component problems later.

Is this an anomoly? Should I be planning on one LC failure
per month? What experience have others had with this
line-card and hardware failures? Any recommendations?

Thanks.
Pete.
