Verify the module is installed correctly. Observe the Module Status LED
for the slot in which the module is being installed, and the Self Test and
Fault LEDs on the switch to verify that the module is installed properly.
Fault LED
When the module is installed properly and the switch is powered on, or
the module is installed when the switch already has power, the module
undergoes a self test that takes a few seconds. You can use the LEDs to
determine that the module is installed properly and has passed the self
test, as described in the "LED Behavior" table below.

If the Module Status, Self Test, and Fault LEDs are flashing, the
module may not be completely installed. Make sure the module is
installed all the way into the switch slot. If the flashing continues,
see the Troubleshooting section on page 18.
