• To force a switchover from an active CPM to a standby, use the admin
redundancy force-switchover command. You can also use the config system
switchover-exec and admin redundancy force-switchover now CLI
commands to configure a batch file that runs after a failover.
6.3 Temperature Threshold Alarm and Fan Speed
Table 29 lists the over-temperature thresholds for 7210 SAS devices.
The 7210 SAS system software controls the fans by monitoring the internal
temperature of the chassis. The software manages the fan speed to maintain the
internal temperature within operational limits.
The 7210 SAS-R6 supports overheat protection reboot. This feature protects the
IMM and CPM cards when the temperature exceeds system-defined temperature
thresholds; these thresholds are not user-configurable. The software monitors the
temperature of each card and if the temperature exceeds the threshold, the system
raises an over-temperature critical event. The system reboots all overheated CPM
