UIDELINES

The RJ-45 ports on the switches support automatic MDI/MDI-X pinout

configuration, so you can use standard straight-through twisted-pair cables

to connect to any other network device (PCs, servers, switches, routers, or

hubs).

“Cables and Pinouts” on page 46

for further information on cabling.

C

AUTION

:

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.

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

Figure 19: Making-Twisted-Pair Connections

2.

If the device is a network card and the switches are in the wiring closet,
connect the other end of the cable segment to a modular wall outlet

that is connected to the wiring closet. (See

“Network Wiring

Connections” on page 38

.) Otherwise, connect the other end of the

cable segment directly to an available port on the switch.

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

in length.
