Twisted-Pair Cable/Connector Pin-Outs - HP ProCurve 8100fl Series Installation And Getting Started Manual

Twisted-Pair Cable/Connector Pin-Outs

The RJ-45 port on the management module and the RJ 45 ports on the 10-Port
100/1000 Base-T interface module operate as MDI-X only and the correct
cable type must be used. In general, for connections to other devices on the
network use a straight-through cable.
Other Wiring Rules:
■ All twisted-pair wires used for 10 Mbps, and 100 Mbps operation must be
twisted through the entire length of the cable. The wiring sequence must
conform to EIA/TIA 568-B (not USOC). See the Pin Assignment tables
below the cable illustrations later in this appendix for a listing of the
signals used on each pin.
■ For 1000Base-T connections, all four pairs of wires in the cable must be
available for data transmission. See "Note on 1000Base-T Cable Require­
ments" on page B-2
For 10 Mbps connections to the ports, you can use Category 3, 4, or 5
■
100-ohm differential unshielded twisted-pair (UTP) or shielded twisted-
pair (STP) cable, as supported by the IEEE 802.3 10Base-T standard.
■ For 100 Mbps connections to the ports, use Category 5 100-ohm differen­
tial UTP or STP cable only, as supported by the IEEE 802.3u 100Base-T
standard.
For 1000 Mbps connections, Category 5 or better 100-ohm differential UTP
■
or STP cable only, as supported by the IEEE 802.3ab 1000Base-T standard;
Category 5e or better is recommended.
