Connecting Ethernet Modules Using MT-RJ Connectors
The Ethernet module, WS-X5015-MT, uses the MT-RJ style connector, shown in
Figure 3-6.
Figure 3-6.
When you are connecting MT-RJ cables to a module, make sure you firmly press the
connector plug into the socket. The upper edge of the plug must snap into the upper front
edge of the socket. You may or may not hear an audible click. Gently pull on the plug to
confirm whether or not the plug is locked into the socket. To disconnect the plug from the
socket, press down on the raised portion on top of the plug (releasing the latch). You should
hear an audible click indicating the latch has released. Carefully pull the plug out of the
socket.

Note
When you disconnect the fiber-optic cable from the module, grip the body of the
connector. Do not grip the connector jacket-sleeve. Gripping the sleeve can, over time,
compromise the integrity of the fiber-optic cable termination in the MT-RJ connector.
compromise the integrity of the fiber-optic cable termination in the MT-RJ connector.
Always make sure that you insert the connector completely into the socket. This is
especially important when you are making a connection between a module and a long
distance (2 km) or a suspected highly attenuated network. If the link LED does not light,
try removing the network cable plug and reinserting it firmly into the module socket. It is
possible that enough dirt or skin oils have accumulated on the plug faceplate (around the
optical-fiber openings) to generate significant attenuation, reducing the optical power levels
below threshold levels so that a link cannot be made.

To clean the MT-RJ plug faceplate:
Step 1
Use a lint-free tissue soaked in 99 percent pure isopropyl alcohol to gently wipe
the faceplate.

Step 2
Carefully wipe the faceplate with a dry lint-free tissue.
Step 3
Remove any residual dust from the faceplate with compressed air before
installing the cable.

Note
Make sure that dust caps are installed on all unused module connectors and unused
network fiber-optic cable connectors.
