Although the following alarm is not identical to the one you identified, this seems to indicate the a peer "communication failure" is hardware related.
2.5.237 PEER-NORESPONSE
Default Severity: Major (MJ), Non-Service-Affecting (NSA)
Logical Object: EQPT
The switch agent raises a Peer Card Not Responding alarm if either traffic card in a protection group does not receive a response to the peer status request message. PEER-NORESPONSE is a software failure and occurs at the task level, as opposed to a communication failure, which is a hardware failure between peer cards.
Hope this helps....
