Determining the status of a management module
You must have at least one management module (MM) active for the chassis to be functional. For
redundancy, you need two management modules. The active management module is designated by
the blue Active LED on the front panel.
Complete the following steps to determine the status of an management module.
1. Locate the LED indicators on the management module (Locating the LED indicators on the
management module on page 60).
2. Observe and interpret the LED pattern. The LED patterns may temporarily change during POST
and other diagnostic tests. For information about how to interpret the LED patterns, refer to
Interpreting the management module LED patterns on page 60.
3. Use the show mm command to determine whether the management modules are enabled. You
can also use the show interface management 1/1 command to see the configuration information.
