MAP2010 RPC card causing false fence

The failing RPC card has an internal problem that is causing it to fence the working RPC card when it should not.

About this task

The false fence must be reset before the failing RPC card can be replaced. The RPC to RPC communication cable will be unplugged so the working RPC card will not continue to be fenced by the failing RPC card.

MAP2010 Section-1

Procedure

Verify that one of the two s is fenced. Observe the green LED on each RPC card. Is the green LED indicator off on one of the cards?
- Yes, continue at the next step.
- No, neither RPC is fenced. The original failing condition is no longer present. Contact your next level of support before cancelling this problem.
Unplug the RPC to RPC communication cable from the J2-08 connector on the failing RPC card (green LED is lit).
Observe the green LED on the working RPC card (green LED was off). Is the green LED indicator lit?
- Yes, continue at the next step.
- No, the working RPC card did not unfence when the RPC to RPC communication cable carrying the fence signal was unplugged. Both RPC cards may be failing. Contact your next level of support.
Return to the SAEL problem screen and continue.
Note: Both RPC cards are not available and normal guided FRU replace procedures will be used.
