*A:CPM-A#
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.
The following console message is displayed when the active CPM goes offline and
the standby CPM assumes the active role:
Active CPM in Slot A has stopped
Slot B is now active CPM
