Accessing the Receiver/Transmitter Module Fiber Spool and Connector
Note Pull up on the built-in handle on RPD, receiver module, transmitter module, status monitor/local control
module, or power supply module.
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
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
Important
If you are using a Local Control Module in the node be sure to press the Auto Set-Up button on the cover of
the LCM before you close the node housing. This allows the 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
LCM. The node must be powered and the modules operating properly in order to be detected.
9. Perform the setup procedure in
Accessing the Receiver/Transmitter Module Fiber Spool and Connector
Optical receivers and transmitter modules have an integrated fiber spool inside the module housing. This
allows the fiber pigtail to be spooled up and contained within the module housing.
You may need to access this spool to clean or replace a fiber pigtail or connector.
Follow this procedure to access the module fiber spool and connector.
1. Pull up on the two module cover knurled tabs. Use a slight rocking motion.
Note If the module is out of the housing, it is easier to hold the module in both hands and push up on the two module
cover knurled tabs with your thumbs. You can also insert a flat blade screwdriver into the cover release tab
slot on the right side of the module housing to assist with opening the cover.
The module cover opens as shown.
