Module Operation
After you install a Management Module in the chassis and before you
install other modules, verify that the Management Module is operating
correctly. This section explains how to verify operation before you begin
to enter commands.
To verify that your Management Module is operating correctly, watch the
four-character LED display located on the front panel during the system
power-on process. Table 5 shows the sequence of characters that appear
in the LED display during a successful system power-on.
The system displays the following message when the Management
Module is installed properly and you have made an RS-232 console
connection:

To ensure that a broken module LED is not providing a false indication of
current conditions, enter the
show chassis
command to verify that
chassis operating conditions are normal.
When two Management Modules are installed in a chassis, and the
Primary Management Module fails over, the Standby LED on that
Management Module continues to display
Active
. This is because only
the SMC component fails over while the SCC component remains active.
