5.1 Alarm Out Relay Interface (RJ-45)
The ONS 15216 EDFA3 Alarm Out (RJ-45) port reports alarm status for the following:
•Loss or degradation of electrical power
•Laser pump overheating or excessive pump current, output power, gain, or case temperature
•Loss or degradation of optical input signal
These alarms can be connected to a network operations center (NOC) using the following methods:
•Cisco ONS 15454 miscellaneous discrete input (See Chapter 13, "Network Access to the ONS 15216 EDFA3 Using the ONS 15454" for more details about the ONS 15454.)
•Central office (CO) alarm panel/system
Table 5-1 provides the ONS 15216 EDFA3 RJ-45 alarm pinout and alarm definitions.

The following procedure describes how to set up alarm contacts. In order to accomplish this, you must:
•Connect the RJ-45 cable to the panel of the ONS 15454 shelf
•Connect the alarm cable to the alarm system contacts
To set up alarm contacts, follow these steps:
Step 1 Connect the RJ-45 cable to the stub-end connector using a #22 AWG solid wire.
Note Note that the cable and connector are not provided.
Step 2 Connect the alarm cable to the alarm system contacts:
a. Cisco ONS 15454 medium-dependent interface (MDI) wire wrap pins, located on the rear panel of the ONS 15454 shelf
b. CO alarm panel
Refer to Table 5-1 for information concerning alarm contacts. Refer to the "Alarm LEDs" section for information about the ONS 15216 EDFA3 alarm LEDs.
5.2 Alarm LEDs
The ONS 15216 EDFA3 has seven LEDs:
•POWER
•FAIL
•LOS
•Ethernet socket (two sockets with two LEDs on each socket)
Three of these LEDs, POWER, FAIL, and loss of signal (LOS), are located at the left side of the front panel of the ONS 15216 EDFA3. 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.
The following table summarizes the external alarms LEDs and contacts.

5.2.1 POWER LED (Green)
The POWER LED is green. This LED functions as follows:
•ON: -48 VDC power is within tolerance. (Power Bus A and Power Bus B are powered normally.)
•OFF: No -48 VDC power, or power is out of tolerance from the internal power supply. (Power Bus A and Power Bus B are not powered.)
•Flashing: In duplex mode, Power Bus A or Power Bus B has failed or is out of tolerance. In simplex mode, Power Bus A is out of tolerance.
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 "Alarm Out Relay Interface (RJ-45)" section on page 5-1.)
5.2.2 FAIL LED (Red)
The FAIL LED is red. This LED has two states:
•ON: The laser pump bias, laser pump temperature, output power, gain, or case temperature is out of tolerance. (A major internal failure has occurred.)
•OFF: The laser pump bias or laser pump temperature is in the specified range (or no -48 VDC power is present).
In the ON condition, the second pair of alarm relay contacts in the RJ-45 connector changes from a normally open to a closed condition. If an invalid input optical signal is applied to the ONS 15216 EDFA3, the FAIL LED is illuminated. The LED and alarm automatically reset when the condition clears.
5.2.3 LOS LED (Yellow)
The loss of signal (LOS) LED is yellow. This LED has two states:
•ON: The optical input power to the ONS 15216 EDFA3 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.
5.2.4 Ethernet Socket LEDs
Two Ethernet socket 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 the left Ethernet socket LED is on, the link is up.
•If the right Ethernet socket LED is on or flashing, there is Ethernet traffic.
5.3 Communicating with the EDFA3 Through a Serial EIA/TIA-232 (RS-232) Interface
This section describes communication with the ONS 15216 EDFA3 using a serial connection. Establishing a serial communications link with a ONS 15216 EDFA3 requires the equipment listed in Table 5-3.
