SAM Redundancy

Slot M has the highest priority, followed in order by slot J, slot F, and slot C. The P- SAM provides redundancy according to the following:

Only a single W-SAM is protected

In the case of more than one request for the P-SAM, only the highest priority W- SAM is protected

If the P-SAM is protecting a W-SAM, then a request from a lower priority W- SAM is ignored until the higher priority clears

If the P-SAM is protecting a W-SAM, then a request from a higher priority W- SAM is honored (and the protection for the first-protected W-SAM is lost)

P-SAM is invoked for removal of a W-SAM, or by user command

Redundancy is not reverting. After correction of a W-SAM problem, switch back manually

Wait at least 15 seconds between removal and insertion of SAMs to ensure system stabilization.

CAUTION! FAILURE TO WAIT 15 SECONDS BETWEEN EVENTS MAY LEAD TO A CONDITION WHERE A W-SAMDOES NOT RETURN TO FULL OPERATION. IN THIS CASE, FOLLOW THE STEPS BELOW TO CORRECT THE PROBLEM.
