This CPM (slot B) is the standby CPM.
6.4.2 Active and Standby Designations on 7210 SAS-Sx/
On the 7210 SAS-Sx/S 1/10GE configured in the standalone-VC mode, the user
must designate and configure two nodes as CPM-IMM nodes. During boot up, one
of the configured nodes assumes the active CPM role and the other assumes the
standby CPM role. Typically, the configured CPMA-IMM node is favored to be the
active CPM and the CPMB-IMM is favored to be the standby CPM. If only one CPM-
IMM node is configured, it becomes the active CPM.
To visually determine the active and standby designations, the Master LED on the
faceplate is lit (steady) to indicate the active designation. The Master LED on the
standby CPM faceplate blinks to indicate the standby designation.
The following output sample shows two nodes configured as CPM-IMM nodes with
one becoming the active node and the other becoming the standby node.

When CPM B boots, it waits 60 seconds to detect an active CPM A. If CPM A does
not respond after 60 seconds, CPM B assumes the role of the active node.

6.4.3 When the Active CPM Goes Offline

When an active CPM goes offline (due to reboot, removal, or failure), the standby
CPM takes control without rebooting or initializing itself. It is assumed that the CPMs
are synchronized, therefore, there is no delay in operability. When the CPM that went
offline boots and comes back online, it becomes the standby CPM.
