Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.
Attaching Switching Module Interface Cables
This section describes how to connect the interface cables to the installed switching modules.
Ethernet and Fast Ethernet Connectors
Figures 5 through 10 illustrate the connector types used to attach interface cables to the Ethernet and Fast Ethernet modules.

Connecting Ethernet and Fast Ethernet Modules
On switching modules using RJ-21 telco connectors, attach the connector to the module and tighten the screws. Secure the right-angle RJ-21 telco connector with a tie wrap to provide strain relief, as shown in Figure 11 and Figure 12.
Figure 11 Securing the RJ-21 Connector to the Ethernet Switching Module
Figure 12 Ethernet Switching Module Telco Cable Attachment
To secure the RJ-21 180-degree cable connection, engage the connector fully and tighten the two screws on either side of the connector, as shown in Figure 13.
Figure 13 Group Switching Ethernet Module and Ethernet Switching Module Connector Attachment
For RJ-45 connectors, plug the interface cable connector into the receptacle on the switching module. Push on the connector until you hear a click, which indicates that the connector is fully inserted and secured in the receptacle.
For the ST and SC connectors, slide the interface cable connector into the switching module receptacle. Make sure that the connector is fully inserted in the receptacle.
Connecting Ethernet Modules Using MT-RJ Connectors
The Ethernet modules WS-X5015-MT, WS-X5236-FX-MT, and WS-X5237-FX-MT use the MT-RJ style connector (shown in Figure 10).
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, degrade 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.
Checking the Switching Module Status
Check the status of the switching module as follows:
- Ensure that the Status LED changes from orange to green when power is applied to the module.
- If you perform a hot swap, ensure that the console displays the message "Module n has been inserted." This message also appears if you are connected to the Catalyst 5000 family switch through a Telnet session.
- If you are replacing a switching module, enter the show module or
show port [mod_num/port_num] command to verify that the system acknowledges the new interfaces and brings them up. If you replace one type of module with another, the show module command responds with a message that the module configuration is inconsistent with the module type and directs you to clear the configuration on that module.

Configuring Ethernet and Fast Ethernet Ports
The following sections briefly describe the commands you need to configure the features on the Ethernet and Fast Ethernet switching modules:
Note Both port speed and port duplex mode features default to auto (autonegotiation). To
customize the two features, you must first set the port speed to 10 or 100 before you set the port
duplex mode to half or full duplex. You cannot have one feature set to auto and the other feature set
to a fixed value.
Note The set port duplex mode is not valid on the group switching Ethernet module (WS-X5020)
and the group switching Fast Ethernet module (WS-X5223).
For complete information on configuring your Ethernet or Fast Ethernet switching modules, refer to the Software Configuration Guide for your switch.
