If an AP is connected to a switch or AC (excluding ACU2), you can run the virtual-cable-
test command on the switch or AC to check network cable connectivity. For details, see the
virtual-cable-test command in the command reference.

Use a network cable tester (high-end cable tester of Fluke) to measure network cable
resistance.
Connect multimeter probes to two ends of each wire in a network cable and check the
resistance value on the multimeter.
Connect a network cable to an AP. Use a multimeter to test the resistance between pins 1
and 2 (or between pins 3 and 6, 4 and 5, or 7 and 8) on the other end of the cable. The
cable's DC resistance approximately equals a half of the displayed value.
