•
Three of these LEDs, POWER, FAIL, and LOS, are located at the left side of the front panel of the
ONS 15216 EDFA2. The two Ethernet LEDs are located at the top left and right sides of the Ethernet
socket. When the module is powered on, an LED test is performed.
3.5.2.1 POWER LED (Green)
The POWER LED is green. This LED functions as follows:
•
•
•
In the off condition, the first pair of alarm relay contacts in the RJ-45 connector changes from a normally
open condition to a closed condition. The LED and alarm automatically reset when the condition clears.
(For additional alarm contact closure information, see the

3.5.2.2 FAIL LED (Red)
The FAIL LED is red. This LED functions as follows:
•
•
In the on condition, the second pair of alarm relay contacts in the RJ-45 connector changes from a
