Installation
This chapter contains the installation procedures for the Cisco ONS 15216 EDFA2. The chapter is divided into the following sections:
•
Power (-48V A, RET A, -48V B, RET B, and chassis ground)
•Optical (fiber input and output ports)
•Communications (Alarm Out, LEDs, RS-232 (EIA/TIA-232), and LAN)
3.1 Standard Precautions
The following standard precautions should be taken when installing the ONS 15216 EDFA2:
•Basic electrical precautions should be taken before powering up the ONS 15216 EDFA2.
•Using standard fiber handling and cleaning procedures is critical when installing optical networking equipment.
•Eye safety precautions should be employed when handling fiber optic patchcords.
3.2 Placement and Power Connection
3.2.1 General Rack Considerations
The following potential hazards should be considered when installing the ONS 15216 EDFA2 within a rack:
•Elevated Operating Ambient Temperature—If installed in a closed or multi-module rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Consideration should be given to installing the equipment in an environment compatible with the manufacturer's maximum rated ambient temperature.
•Reduced Air Flow—Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Do not block ventilation holes beyond what is allowed with supplied mounting brackets.
•Mechanical Loading—Mounting of the equipment in the rack should be such that it avoids uneven mechanical loading.
•Circuit Overloading—Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used.
•Reliable Earthing—Reliable grounding of rack mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (i.e., use of power strip, etc.).
Warning The ONS 15216 EDFA2 is intended for installation in a restricted access area. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock, key, or other means of security. A restricted access area is controlled by the authority responsible for the location.
3.2.2 Rack Installation and Power Supply Connection Procedures
Warning Before performing any of the following procedures, ensure that the power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Follow these steps to install the ONS 15216 EDFA2 into the rack and correctly set up the power supply:
Step 1 Mount the ONS 15216 EDFA2 in the rack (19 inches or 23 inches reversible ears). Empty rack space is not required above or below the ONS 15216 EDFA2.
Step 2 Connect the -48 VDC power cable to the office fuse panel (user-provided).
a. 1.5A fusing is required (user-provided).
b. Use 18 AWG stranded wire (and wire lugs as appropriate).
Step 3 Connect power cable from the office fuse panel to the power bus A terminals on the ONS 15216 EDFA2. See Figure 2-2.
Step 4 Repeat Step 3 for power bus B.
Step 5 Connect the facility ground to the ONS 15216 EDFA2 side panel ground using #10-32 x 3/8-inch fasteners with lock washers and ground lugs, or connect to the rear panel ground using ring lugs for #8 studs.
Step 6 Insert 1.5A fuses into the fuse panel (user-provided).
Step 7 While the ONS 15216 EDFA2 is booting, the following LED behavior should be observed:
a. The POWER (green), FAIL (red), and LOS (yellow) LEDs all turn on.
b. The POWER LED flashes for approximately 1 second, the FAIL LED flashes for approximately 1 second, and the LOS LED flashes for approximately 1 second.
c. The POWER, FAIL, and LOS LEDs all turn on.
d. The alarm relays click, indicating that boot process has completed. This occurs because the software sets the relays to their default state and then determines the relay settings based on alarm conditions.
e. The POWER (green) LED remains on if the Power Bus mode is duplex and both power supplies are connected to valid power sources or if the Power Bus mode is simplex and the Power A terminal is connected to a valid power source. Note that the POWER LED could flash for a few seconds while the software determines the validity of the power sources. A continuously flashing POWER LED indicates a Power Bus alarm.
f. The FAIL (red) LED state depends on alarm conditions. The LOS (yellow) LED state depends on the condition of the optical input signal.
3.3 SC/UPC Optical Ports
SC/UCP optical ports are as follows:
•Optical input signal to be amplified (INPUT)
–Input must be between -27 dBm and +4 dBm
•Optically amplified output (OUTPUT)
•Optical monitored output signal (MONITOR OUT)
–1% tap of output or 20 dB below output signal
3.3.1 Safety Requirements
Warning Procedures that require the fiber connections to be open must only be performed by service personnel trained in laser safety requirements. Use of controls or performing adjustments or procedures other than those specified herein may result in hazardous radiation exposure.
Warning Class 1M laser radiation when open. Anyone working with the ONS 15216 EDFA2 must not allow their eyes or body to be exposed to the laser beam or to a reflection from a mirror-like surface. Additionally, viewing the laser output with certain optical instruments (eye loupes, microscopes) within a distance of 100 mm may pose an eye hazard.
Warning In the event of a fiber cut or loss of connection and there is no input power, the ONS 15216 EDFA2 still has approximately -3.5 dBm of optical output power.
The TL1, SNMP, and command-line interface (CLI) commands can be used to increase the level of laser energy. Necessary precautions must be taken to avoid exposure to laser energy when using these commands.
3.3.2 Optical Connection Procedure
Warning Follow all directions and warning labels when working with optical fibers. To prevent eye damage, never look directly into a fiber or connector.
Connect the customer-supplied fiber optic patchcords to the SC/UPC optical ports of the ONS 15216 EDFA2 using the following procedure. Refer to Figure 3-1 while performing this procedure:
Step 1 Clean both ends of the two fiber optic patchcords. Refer to the Cisco document "Cleaning Procedure for Fiber Optic Connectors" for more information.
Step 2 Connect the first patchcord between the ONS 15216 EDFA2 OUTPUT connector and the FACILITY LINE connection.
The measured optical output power should be approximately -3.5 dBm.
Step 3 Connect the second patchcord to TERMINAL OUTPUT. Measure and record the total optical power:
a. DWDM/OADM output
b. Terminal transmitter output
Step 4 If optical power at the end of the TERMINAL OUTPUT patchcord is less than or equal to +4 dBm, connect the end to the ONS 15216 EDFA2 input. If the optical power is greater than + 4 dBm, additional optical attenuation is required to bring optical power below + 4 dBm.
Figure 3-1 ONS 15216 EDFA2 Optical Connections
3.3.3 Optical Amplification Operation Verification Procedure
To verify ONS 15216 EDFA2 optical amplification, use the following procedure:
Step 1 Connect an optical power meter to the MONITOR OUT port.
Step 2 Measure and record the output power. The MONITOR OUT port level is -20 dB less than the signal.
Step 3 Verify that the ONS 15216 EDFA2 input and output power are within the range shown in Table 3-1.
For example, if the total input power is between -27 dBm and -5 dBm, expect an output power between -5 dBm and 17 dBm.

Refer to Table 3-2 for information concerning alarm contacts. Refer to Alarm LEDs for information on the ONS 15216 EDFA2 alarm LEDs.
3.4.2 Alarm LEDs
The ONS 15216 EDFA2 has five LEDs:
•POWER
•FAIL
•LOS
•Ethernet socket (2)
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.
3.4.2.1 POWER LED (Green)
The POWER LED is green. This LED functions as follows:
•On: -48 VDC power is within tolerance. (Power Bus A and B are powered normally.)
•Off: No -48 VDC power or power is out of tolerance from the internal power supply. (Power Bus A and B are not powered.)
•Flashing: Power Bus A or B (in duplex mode) has failed or is out of tolerance, or Power Bus A (in simplex mode) 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.)
3.4.2.2 FAIL LED (Red)
The FAIL LED is red. This LED functions as follows:
•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 EDFA2, the Fail LED is illuminated. The LED and alarm automatically reset when the condition clears.
3.4.2.3 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.
3.4.2.4 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.

3.4.4.6 PC Connection via Modem
The ONS 15216 EDFA2 and modem are connected through the RS-232 (EIA/TIA-232) port using a DB-9 connector. The modem, PC, and ONS 15216 EDFA2 should be physically set up as displayed in Figure 3-8. Use Figure 3-8 to properly connect the ONS 15216 EDFA2 to the modem.
Figure 3-8 DB-9 Pinout for RS-232 (EIA/TIA-232) Port
Using the terminal program from the PC, enter the ATDT command with the appropriate telephone number to call the remote ONS 15216 EDFA2 modem. After the modems synchronize, log into the ONS 15216 EDFA2 using the correct user name and password. Refer to "SNMP MIB Configuration," Chapter 6, "ASH Commands," and "TL1 Commands," for additional information on commands.
3.4.5 LAN Interface (Ethernet)
You can connect to the ONS 15216 EDFA2 to an Ethernet LAN for remote access.
Note Before communicating and managing the ONS 15216 EDFA2 via the Ethernet port, the user must first enter an IP address. To set an IP address, see "Provisioning with ASH and SNMP" or "Provisioning with TL1."
Telnet is an application that allows remote management using IP over the Ethernet LAN. The following types of commands can be issued through a Telnet session:
•SNMP MIB commands ( "SNMP MIB Configuration")
•ASH CLI commands ( Chapter 6, "ASH Commands")
•TL1 commands ( "TL1 Commands")
3.4.5.1 LAN Connection Procedure
Use the following procedure to configure the module to accept SNMP, CLI, and TL1 commands via its RJ-45 LAN port:
Step 1 The ONS 15216 EDFA2 IP address is factory set at 0.0.0.0. The IP address must be set before the ONS 15216 EDFA2 can be accessed via the Ethernet port. See the "Set IP Address" section.
Step 2 Connect ONS 15216 EDFA2 to the network via the module LAN port.
Use a straight-through Cat5 Ethernet cable with RJ-45 connectors to connect to a LAN, or use a cross-over cable if connecting directly to a PC.
Step 3 At a terminal or workstation, open the Telnet application.
Note To send CLI and TL1 commands over IP, a Telnet client is required. For SNMP management over IP, a generic SNMP manager is required.
Step 4 Connect to the ONS 15216 EDFA2 using the module's IP address.
If you do not specify a port number, the ONS 15216 EDFA2 responds in the shell that the ONS 15216 EDFA2 is set to (TL1 is the default shell). Specify port number 8023 to access through the ASH shell or port number 3083 to access through the TL1 shell.
The ONS 15216 EDFA2 login screen appears. See the "Log In via RS-232 (EIA/TIA-232) Port Using HyperTerminal" section for the login procedure in ASH shell and the "Log In via RS-232 (EIA/TIA-232) Port Using HyperTerminal" section for the login procedure in TL1 shell.
