3.5.2.3 LOS LED (Yellow)

The loss of signal (LOS) LED is yellow. This LED functions as follows:

•On: The optical input power to the ONS 15216 EDFA2 is below the loss of input threshold. (A LOS threshold decision occurs.)

•Off: The optical input power is within the input threshold (or no –48 VDC power is present).

In the on condition, the third 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.

3.5.2.4 Ethernet Socket LEDs

Two LEDs are located at the top left and right sides of the Ethernet socket. These LEDs are both green. These LEDs function as follows:

•If left Ethernet socket LED is on, the link is up.

•If right Ethernet socket LED is on or flashing, there is Ethernet traffic.

3.5.3.2 Serial Connection Procedure

To set up an EIA/TIA-232 link to the ONS 15216 EDFA2, use the following procedure. (The procedure uses HyperTerminal and a connection via the COM1 port.)

Step 1	Connect the DB-9F end of the EIA/TIA-232 data cable (straight cable, user provided) to the laptop COM
	port.
Step 2	Connect the DB-9M end of the EIA/TIA-232 data cable to the RS-232 (EIA/TIA-232) serial port
	connection on the front panel of the ONS 15216 EDFA2.
Step 3	Open HyperTerminal. (HyperTerminal can be found in the Microsoft Windows Accessories menu.)
Step 4	Type Optical Amplifier, select an icon, and click OK.
