Access Point Port and Network Cables

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 device such as switch or 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.
