MAP Cable Requirement
Use a straight-through Ethernet cable to connect a MAP access point
directly to a WX switch or indirectly through another device.
1000BASETX Gigabit Ethernet Cable Wiring Use Cat 5 Enhanced
(Cat
5E) or better cable. 1000BASE-TX uses all 8 wires in the cable. The
wiring can be straight-through or crossover. The port automatically
configures its pin signals accordingly.
PoE is not supported on 1000BASE-TX links. All wires in the cable are
used for data.
