3 Loosen the screws securing the module.
4 Lift the module straight up out of the housing to unplug it.

5 Position the new module in the same location and carefully slide the module into
its slot until connected to the optical interface board.
6 Tighten the screws securing the module. Torque screws to 25 to 30 in-lbs (2.8 to
3.4 Nm).
7 Carefully reconnect any optical fibers that were removed from the original
module. Clean optical connectors before reconnecting. See Care and Cleaning of
Optical Connectors (on page 148) for cleaning procedure.

WARNING:
Laser light hazard. Never look into the end of an optical fiber or
connector. Failure to observe this warning can result in eye damage or
blindness.

8 Close the housing. See Opening and Closing the Housing (on page 136).
Important: If you are using a Status Monitor/Local Control Module in the node
be sure to press the Auto Set-Up button on the cover of the SM/LCM before you
close the node housing. This allows the SM/LCM to check for, and detect,
installed modules. If the modules are not detected during this discovery process,
they cannot be monitored and controlled by the SM/LCM. The node must be
powered and the modules operating properly in order to be detected.

9 Perform the setup procedure in Chapter 4 to verify node performance.
Optical Amplifier and Optical Switch Module Pin Adaptor
Both the EDFA optical amplifier modules and the optical switch module require the
use of a pin adaptor to be mounted in the node lid and connected to the optical
interface board.
Optical transmitters and optical receivers can only be mounted on their respective
sides in the node lid, transmitters on the right and receivers on the left. The pin
alignment on these modules is slightly different to prevent accidentally installing a
receiver in a transmitter slot or a transmitter in a receiver slot.
Since the optical amplifier and optical switch modules can be mounted on either the
left-hand or right-hand side, they require a reversible pin adaptor that can match the
pin alignment for either a transmitter or a receiver slot.
The reversible pin adaptor is color coded. One side is blue and the other side is red.
To install the module in a transmitter slot, assemble the pin adaptor on the module
with the red side facing outward. To install the module in a receiver slot, assemble
the pin adaptor on the module with the blue side facing outward.
