This chapter describes how to prepare your Catalyst 4500 series switch for the installation of the supervisor engines and switching modules. The information is presented in these major sections:

This chapter does not tell you how to install your Catalyst 4500 series switch. For that information, see Chapter 3, "Installing the Modules."
Connecting a Terminal to the Management Port
The Ethernet management port, located on the front panel of the Catalyst 4500 series supervisor engine, is shown in the previous chapter in Figure 1-1 through Figure 1-8. The Ethernet management port uses an RJ-45 media-dependent interface crossed-over (MDIX) connector (see Figure 2-1).
Note
See the tables in Appendix A, "Port Pinouts, Environmental Specifications, and Power Consumption Information," for port pinouts.

Connecting a Terminal to the Console Port
The console port, located on the front panel of the Catalyst 4500 series supervisor engine, is shown in the previous chapter in Figure 1-1 through 1-8. See the tables in Appendix A, "Port Pinouts, Environmental Specifications, and Power Consumption Information," for port pinouts. All other supervisor engine console ports use an RJ-45 connector.
Connecting Ethernet Ports with MT-RJ Connectors
Use the guidelines shown in Table 2-1 for switching modules that have MT-RJ connectors (see Figure 2-2).
Table 2-1 MT-RJ Connector Guidelines
Optical transmit power
-19 to -14 dbm1 average for 62.5/125 um fiber;
-23.5 to -14 dbm average for 50/125 um fiberReceiver sensitivity
-33.5 dbm average at window edge;
34.5 dbm average at window center
1 dbm = decibels per milliwatt

When you are connecting MT-RJ cables to a module, make sure that you firmly press the network cable plug into the socket. The upper edge of the plug must snap into the upper front edge of the socket. You might hear an audible click. Gently pull on the plug to determine 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, which would indicate that the latch has released. Carefully pull the plug out of the socket.
Note
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 possibly a highly attenuated network. If the link LED does not light, try removing the network cable plug and reinserting it firmly into the module socket.
Dirt or skin oils also may have accumulated on the plug faceplate (around the optical-fiber openings), which can generate significant attenuation and reduce the optical power levels below threshold levels so that a link cannot be made.
To clean the MT-RJ plug faceplate, follow this procedure:

Installing, Removing, and Maintaining Optical Modules
The Catalyst 4500 series switch supervisor engines and switching modules support various types of transceiver module depending on the module or supervisor type. Transceiver types supported include X2, GBIC, SFP, TwinGig, and OneX. Refer to the following installation notes as needed.
