Access Point Port and Network Cables

Twisted-Pair Cable/Connector Pin-Outs

Twisted-Pair Cable/Connector Pin-Outs
The access point includes one 10/100Base-TX port. This port uses MDI (i.e.,
internal straight-through) pin configuration. You can therefore use "straight-
through" twisted-pair cable to connect this port to most network interconnec-
tion devices such as a switch or a router that provide MDI-X ports. However,
if you need to connect the access point to a workstation or other device that
only has MDI ports, then use "crossover" twisted-pair cable.
Ports on most HP switches have the "HP Auto MDIX" feature, which means
that you can use either straight-through or crossover twisted-pair cables to
connect the access point to the switch.
Other Wiring Rules:

B-2
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 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 stan-
dard.
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.
