(for the slot in which you are installing the module) The LED goes
ON as soon as the module is installed and the switch is powered on,
and stays ON steadily.
Test ON briefly while the module is being tested, then OFF.
Note: If the switch was powered off while the module was installed,
when the switch is powered on, the Test LED will stay ON for the
duration of the whole switch self test.
Fault OFF
Link and Mode (on

approximately 3 to 10 seconds, then OFF for 5 to 10 seconds
depending on the module. Then, the Test LED on the switch goes OFF.
If the module is already installed when the switch is powered on or
r

set, the process described above occurs approximately 30
seconds after the power on or reset, during which the switch is
being tested.
