. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-1 Chapter 2 Media Expansion Options The repeater contains a Media Expansion Port (MEP) that gives you the option of installing one of several Alternate Media Connectors (AMCs) to expand the network to other media. Each connector is sold separately. This chapter describes these connectors and how to install each.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-2 Media Expansion Options IMPORTANT: If there is no connection or external terminator at the BNC port, set the jumper to the OFF position. Otherwise, excessive collisions will occur and adversely affect network performance. The AW1 jumper settings are shown in Figure 2-2: ON AW1 BNC Disabled OFF BNC Enabled (Default) Figure 2-2. AW1 Jumper Settings To install a BNC connector, follow these steps: 1.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-3 4. Insert the BNC connector through the MEP opening and carefully push the 20-pin plug into the outlet on the repeater board until the AMC is secure. 5. Tighten the screws on the faceplate. 6. Restart the repeater. For information about starting the repeater, see the section “Connecting Power” in Chapter 3 of this guide.

The chapter also explains how to rack mount and power up the repeater, how to make a basic repeater-to-workstation connection, and how to set up some basic network configurations.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-2 Setting Up the Repeater Data communications equipment is sensitive to variations in voltage supplied by AC power supplies. Overvoltage, undervoltage, or transients can interfere with data integrity and may damage your equipment. CAUTION To protect against these voltage-related problems, power cables should be properly grounded and the following power management methods should be employed: • Use power protection devices.
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-3 3. To install the brackets in the repeater, insert the bracket clips into the bracket slots on the bottom of the repeater. The brackets rest flat against the bottom and the sides of the repeater, while the mounting holes that secure the bracket to the rack face the front of the repeater. To flushmount the repeater, use Slots 1 and 3 (see Figure 3-1). To have the repeater extend slightly out of the rack, use Slots 2 and 4. 4.

To remove a bracket from the repeater, pull the bracket forward until it unsnaps from the plastic ridge inside the mounting slot. Connecting Power To connect the repeater to power, follow these steps: 1. Plug the female IEC connector of the power cord into the power cord outlet on the back of the repeater. 2.

This distance must include all cross-connect wire, wire in the walls, and any drop cables from wall plates to workstations (see the next section to determine the proper length). Maximum distances may be less for UTP cable run underground, in conduit, or in large cable bundles.

Plug one end of the modular cord into a 10Base-T-equipped workstation. 2. Plug the other end of the modular cord directly into the desired port on the repeater, as shown in Figure 3-5. The maximum end-to-end cable distance is 328 feet (100 meters).
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3-9 Setting the Uplink Switch The uplink switch on the front panel of the repeater converts Port 16 to an uplinkable port. This feature allows the repeater to connect to another repeater in a star topology. The default setting for the uplink switch is MDI-X (the standard RJ-45 port). The uplink switch helps simplify twisted-pair wiring between repeaters. Typically, the repeater's RJ-45 jacks function as input ports for workstation connections.
