Determining the status of a management module

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 MMs. The active MM is designated by the blue Active LED on the front
panel.
Complete the following steps to determine the status of a MM.
1. Check the LED indicators on the module ( Figure 7 ). The LED patterns may temporarily change
during POST and other diagnostic tests. For information about how to interpret the LED
patterns, refer to
Table 10 .
2. You can use the show mm command to see whether the management modules are enabled.
You can also run the show interface management 1/1 to see the configuration information.
Figure 7 identifies the management module.

No light (LED is off) MM is not powered on. Ensure that the module is firmly
seated and has power.
Status No light (LED is off) MM is either healthy or does
not have power.

still booting up.

module is faulty. Consult the
