NOTE
Then the 40 GbE ports are in breakout mode on the 27x40 GbE and 12x40 GbE line cards, operating
status cannot be determined from LED operation.
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 an MM.
1. Check the LED indicators on the module ( Figure 15 ). The LED patterns may temporarily change
during POST and other diagnostic tests. For information about how to interpret the LED
patterns, refer to
Table 11 .
2. You can use the show mm command to see whether the management modules are enabled.
You can also use the show interface management 1/1 command to see the configuration
information.
