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
To display the status of the management modules, enter the following command at any CLI level.
Syntax: show module
The Status column indicates the module status. The management modules can have one of the
following status:
•
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.
•
Ready – 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.
Displaying temperature information
Each management module contains a temperature sensor. By default, the BigIron RX system polls
the temperature of each management module every 60 seconds. You can display the current
temperature of the management modules (and all other modules) by entering the following
command at any CLI level.
Syntax: show chassis
The output displays the temperature of the management modules in the BigIron RX device and also
indicates that the temperature readings were provided within the last 60 seconds.
