Patch Cables

When installing your equipment, replace old patch panel cables that do not meet Category 5e
specifications. As pointed out in the NEXT section, this near end piece of cable is critical for
successful operation.
RJ-45 Plug and RJ-45 Connectors
In a Fast Ethernet network, it is important that all 100BASE-T certified Category 5 cabling use RJ-
45 plugs. The RJ-45 plug accepts 4-pair UTP or shielded twisted-pair (STP) 100-ohm cable and
connects into the RJ-45 connector. The RJ-45 connector is used to connect stations, hubs, and
switches through UTP cable; it supports 10 Mbps, 100 Mbps, or 1000 Mbps data transmission.
Figure C-4 shows an RJ-45 plug and RJ-45 connector with built-in LEDs.
