Cabling and Technology Information
Twisted-Pair Cable/Connector Pin-Outs
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 “Twisted-Pair Cable Pin Assignments” 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-2for more information on 1000Base-T cabling.
■For 10 Mbps connections to the ports, you can use Category 3, 4, or 5 unshielded twisted-pair cable, as supported by the IEEE 802.3 Type 10Base-T standard.
■For 100 Mbps connections to the ports, use 100-ohm Category 5 UTP or STP cable only, as supported by the IEEE 802.3u Type 100Base-TX standard.
■For 1000 Mbps connections, 100-ohm Category 5e or better cabling is recommended.
■To provide Power over Ethernet to the access point, all 4 pairs must be connected for any network cable attached to this port; the cable must meet ISO/DIS 11801 Class D requirements and IEEE 802.3af requirements.
