Installing the Modules
Verifying the Module is Installed Correctly
Observe the Module Status and Fault LEDs on the front of the switch to verify
the module is installed properly.
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.
