Configuration
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.
