Monitoring management module redundancy
•
The switchover history for the management modules
The following sections explain how you can monitor the management modules
Determining management module status
You can determine the status of a management module in the following ways:
•
LEDs - The LEDs on the management module indicate whether a module is the active module or the standby module, and if
the module has power.
•
Redundant management and module information in software - The module information displayed by the software indicates
whether a module is the active module or the standby module.
Status LED
If you are located near the chassis, you can determine which management module is currently the active module and which is the
standby module by observing the Active LED on each module. If this LED is on (green), the module is the active module. If this LED is
off, the module is the standby module.
You can also observe the Pwr LED on each module. If this LED is on (green), the module is receiving power. If this LED is off, the module
is not receiving power. (A module without power will not function as the active or standby module.)
Software
You can use the show module CLI command to display the status of the management modules.
The following shows an example output of the show module command.

Syntax: show module
The Status column indicates the module status. The management modules can have one of the following statuses:
•
ACTIVE - The module is currently the active management module.
•
STANDBY - The module is the standby management module. The status of the standby module can be one of the following:
–
Init - The module is currently initializing as the standby module.
–
OK - The module is ready to take over as the active module, if necessary.
–
Wait - The module is awaiting boot information from the active management module.
–
Sync - The active module is currently synchronizing files between itself and the standby module.
