Installation
This chapter discusses the ONS 15216 EDFA1 installation procedure, which includes power installation, optical cabling, alarm contacts, and installation commands.
The ONS 15216 EDFA1 is logically divided into the following three sections:
•
Power section (-48V A, RET A, -48V A, RET B, and chassis ground)
•Optical section (fiber input and output ports)
•Communication section (RS-232 and Alarm Out)
Each section ( Figure 3-1) has an installation procedure in this chapter.

Power Installation
Warning Basic electrical precautions should be taken before powering up the EDFA.
Caution Standard fiber handling and cleaning procedures should be followed. Fiber optic handling and cleaning procedures are critical when installing optical networking equipment.
Warning Eye safety precautions should be observed when handling fiber optic patch cords.
Procedure: Install the ONS 15216 in a Rack
Step 1 Mount the ONS 15216 EDFA1 in the rack (19" and 23" reversible ears). Empty rack space is not required above or below the EDFA.
Step 2 Connect the -48VDC cable to the office fuse panel. Note that 1.0A fusing is required and that 18AWG stranded wire or larger must be used. Connect wire lugs as appropriate to ends of wire (not provided).
Step 3 Connect power buss A from the fuse panel to the ONS 15216 EDFA1 power terminals.
Step 4 Repeat steps 2 and 3 for power buss B.
Step 5 Connect the facility ground to the ONS 15216 EDFA1 front panel ground using #8/32 star washer and 3/4" screws (not provided).
Step 6 Insert the fuses into the fuse panel.
LEDs should now be illuminated on the ONS 15216 EDFA1.

Optical Connections
Procedure: Connect the customer-supplied fiber patch cords to the SC/UPC optical ports
Step 1 Connect the fiber carrying the optical-input signal to be amplified (INPUT) to the fiber input port of the ONS 15216 EDFA1 (not provided).
Step 2 Connect the fiber carrying the optically-amplified output (OUTPUT) to the fiber output port of the ONS 15216 EDFA1 (not provided).
Step 3 If applicable, connect the fiber carrying the optical monitored output signal (MON OUT) to the fiber output monitor port (for 1% tap of output

Communication Connections
The ONS 15216 EDFA1 communicates in two ways: alarm contacts (RJ-45) and the serial interface (RS-232).
See the "Local Serial Communication Setup" section for detailed information about the RS-232 serial interface.
Procedure: Set Up Alarm Contacts
Step 1 Obtain an 8-conductor, 22 AWG solid-wire cable and terminate one end with an RJ-45 connector.
Step 2 Connect the stub end of the alarm cable to the alarm system contacts, either as miscellaneous discrete inputs on terminal equipment or to a central office alarm panel.
Step 3 Connect the RJ-45 end to the ONS 15216 EDFA1.
See the "Alarm Contact Closures" section and the "ONS 15216 LED Alarm Definitions" section on page 2-7 for further information.

Installation Commands
You can connect to an ONS 15216 locally using a serial connection or remotely using a modem.
See the "Local Serial Communication Setup" section and the "Remote Communication Component Requirements" section for information.
After you establish connection, use the following commands to complete the hardware installation. See Chapter 5, "Command Line Reference" for detailed information about each of these commands. Table 5-17 on page 5-26 summarizes all of the ONS 15216 EDFA1 commands.
Installation-Introductory Commands
You can use the following commands to first establish communication with the ONS 15216 EDFA1 and gain access to additional information about the amplifier.
•@00- Use this command to log in and establish a connection to the EDFA1. The default address for the EDFA is "00".
•HELP- Use this command to review all of the available commands.
•PASS- This command enables you to use password-protected commands. All commands which affect system operation or alarm-threshold parameters are password protected. Prior to using any password-protected commands, you must first enter the PASS command with the correct password. The factory-set password is "CISCO". See the "PASS" section on page 5-17 for information about changing the password.
•VER- This command accesses information about the ONS 15216 EDFA1 software and hardware. After entering this command, record the identification and inventory information.
Installation-Review and Operational Commands
You can use the following commands to review the overall status of the EDFA and to make basic configuration changes.
•STAT- Review the operational status of the EDFA
•SETADDR- Changes the numerical address of the 15216 EDFA1; use this command to change the default address, "00"
•ALMENBL- Enables alarm checking for a specified alarm
•ALMDSBL- Disables an alarm
•ALARM C- Clears alarm count
•SET_LOSTH- Set, enable, disable, or display the loss-of-input signal threshold; the factory default is set to -30 dBm
•SET- Set operational modes of the ONS 15216 EDFA1; for example,
–SETGT command- sets EDFA to constant gain mode temperature compensated (the factory default)
–SETI command- sets the specified pump laser to constant current mode
–SETOUT command- sets EDFA to constant output power mode
–SETP command- sets specified pump laser to constant output power
•CONFIG S- Saves configuration changes in active memory; you must save configuration changes or they will be lost by a power reset, inactivity, or the LOGOUT command
•LOGOUT- Terminates the active session
