Verifying the controller is installed correctly
When the controller is installed properly, it undergoes a self test that takes a few seconds. This
happens both when the switch is powered-on after installing the controller and when the controller
is installed while the switch already has power. The LEDs help determine if the controller has passed
the self test, as described in the following table.

On briefly while the controller is undergoing self test, then off.
Note
: If the controller was installed with the switch powered off,
and then the switch was powered on, the Test LED will stay on for
the duration of the switch self test.
