The secondary parameter specifies that the management module will be reloaded
with the secondary image.
Verifying the new software image
Enter the show version command at any CLI level to verify that all management
and interface modules are running the new software image version.
Monitoring management module redundancy
You can monitor the following aspects of management module redundancy:
v The status of the management modules (if a module is the active or standby
v 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:
v LEDs - The LEDs on the management module indicate whether a module is the
v Redundant management and module information in software - The 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.
