Cabling Guidelines
The RJ-45 ports on the switch 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).
See Appendix B for further information on cabling.
Caution: Do not plug a normal 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.
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 4-1. 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.”) 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 green Link LED (on the switch) corresponding
to each port will light to indicate that the connection is valid.
