Before testing hardware, confirm that all outdoor cables, that is those that connect the AP or SM to
equipment inside the building, are of the supported type, as defined in

POWER LED IS OFF
Meaning: Either the power supply is not receiving power from the AC/DC outlet, or there is a
wiring fault in the unit.
Action: Remove the AP/SM cable from the PSU and observe the effect on the Power LED. If the
Power LED does not illuminate, confirm that the mains power supply is working, for example,
check the plug. If the power supply is working, report a suspected power supply fault to Cambium
Networks.
ETHERNET LED IS OFF
Meaning: There is no Ethernet traffic between the AP/SM and power supply.
Action: The fault may be in the LAN or AP/SM cable:
Remove the LAN cable from the power supply, examine it and confirm it is not faulty.
If the PC connection is working, remove the AP/SM cable from the power supply, examine it,
and check that the wiring to pins 1&2 and 3&6 is correct and not crossed.
