CABLES

Twisted-Pair Cable and Pin Assignments

&DXWLRQ￿ DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

&DXWLRQ￿ Each wire pair must be attached to the RJ-45 connectors in a specific orientation. (See “Cabling Guidelines” on page -1 for an explanation.)

The figure below illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.

10BASE-T/100BASE-TX Pin Assignments

Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3, 4 or 5 cable for

10Mbps connections or 100-ohm Category 5 cable for 100 Mbps connections. Also be sure that the length of anytwisted-pair connectiondoes not exceed 100 meters (328 feet).

The RJ-45 ports on the switch base unit support automatic MDI/ MDI-X operation, you can use straight-through cables for all
