Making Network Connections

Connecting to PCs, Servers, Hubs and Switches
Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the
switch. Use only twisted-pair cables with RJ-45 connectors that conform to
FCC standards.
1. Attach one end of a twisted-pair cable segment to the device’s RJ-45
connector.
Figure 4-1. Making Twisted-Pair Connections
2. If the device is a PC 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 “Wiring Closet Connections” on the next page.) Otherwise, attach
the other end to an available port on the switch.
3. Make sure each twisted pair cable does not exceed 100 meters (328 ft) in
length.
Note: When connected to a shared collision domain (such as a hub with multiple
workstations), switch ports must be set to half-duplex mode.
4. As each connection is made, the green Link LED (on the switch) corresponding
to each port will light to indicate that the connection is valid.
Wiring Closet Connections
Today, the punch-down block is an integral part of many of the newer equipment
racks. It is actually part of the patch panel. Instructions for making connections in the
wiring closet with this type of equipment follows.
1. Attach one end of a patch cable to an available port on the switch, and the other
end to the patch panel.
2. If not already in place, attach one end of a cable segment to the back of the
patch panel where the punch-down block is located, and the other end to a
