cards and powers off all overheated IMM cards to reduce the heat generated, which
consequently cools down the chassis. The system powers back on the IMM cards
after the temperature is reduced. Operators are still required to take immediate
action for an over-temperature critical event. Refer to the 7210 SAS-R6 Chassis
Installation Guide for more information about maintaining the operating temperature.
6.3.1 Synchronization
This section describes the synchronization between the CPMs or CFMs.
6.3.1.1 Configuration and boot-env Synchronization
Configuration and boot-env synchronization are supported in the
admin>redundancy>synchronize and config>redundancy>synchronize
contexts.
6.3.1.2 State Database Synchronization
If a new standby CPM or CFM is inserted into the system, it synchronizes with the
active CPM or CFM upon a successful boot process.
If the standby CPM or CFM is rebooted, it synchronizes with the active CPM or CFM
after a successful boot process.
When configuration or state changes occur, an incremental synchronization is
conducted from the active CPM or CFM to the standby CPM or CFM.
If the synchronization fails, the standby CPM or CFM does not reboot automatically.
Use the show redundancy synchronization command to display synchronization
output information.
Note: Nokia recommends that when planning their availability design, operators must
consider CPM card reboot handling that is caused when the system temperature exceeds
system-defined thresholds. Failure to build in network redundancy may result in network
and service downtime.
