Chapter 4 Replacing the SFP Module
SFP Module Replacement Process
Step 9 Grasp the SFP module between your thumb and index finger, and carefully remove it from the module
slot.
Step 10 Place the removed SFP module in an antistatic bag or other protective environment.
Caution Do not remove the rubber plugs from the SFP module port or the rubber caps from the
fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP
module ports and cables from contamination and ambient light.
Step 11 Find the send (TX) and receive (RX) markings that identify the top side of the replacement SFP module.
Note On some SFP modules, the send (TX) and receive (RX) markings might be replaced by arrows
that show the direction of the connection, either send or receive (TX or RX).
Step 12 Align the SFP module in front of the slot opening.
Step 13 Insert the SFP module into the slot until you feel the connector on the module snap into place in the back
of the slot.
Step 14 Remove the dust plugs from the SFP module optical ports. Store the plugs for later use.
Caution Do not remove the dust plugs from the SFP module port or the rubber caps from the fiber-optic
cable until you are ready to connect the cable. The plugs and caps protect the SFP module
ports and cables from contamination and ambient light.
Step 15 Clean the fiber-optic connectors by using standard procedures.
Step 16 Insert the LC cable connector into the SFP module.
Step 17 Verify that the gasket is in place and replace the antenna end cap by using a 3/8-inch socket wrench to
remove the bolts, torquing the bolts to 58 to 68 in-lb.
