CHAPTER 4 Making Network Connections

Twisted-Pair Devices

CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES

1.Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.

Figure 21: Making Twisted-Pair Connections

2.If the device is a network card and the switch is in the wiring closet, attach

the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See the section “Network Wiring Connections” on page 57.) Otherwise, attach the other end to an available port on the switch.

Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

NOTE: Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub.

3.As each connection is made, the Link LED (on the switch) corresponding to each port will light green (1000 Mbps) or yellow (10/100 Mbps) to indicate that the connection is valid.
