Powering the Access Point
If multiple power sources are available, the access point will select the power source which is higher
on the following prioritization list. If a power source is removed, access point will automatically switch
to the next available power source, as per this list:

Power-over-Cable

All versions of AP1572I and some versions of AP1572E are equipped with a power-over-cable (PoC)
power supply. The power supply can accept quasi-AC signals in the 40 to 90 V RMS range.
Versions of the AP that have a PoC power supply, also have a shunt/fuse interface providing direct
in-line access to the PoC AC signal. The AP comes with a shunt in the shunt/fuse location. By removing
the shunt or fuse, field technicians can immediately remove power to the AP for service and repairs,
and then restore power by re-installing the shunt or fuse. You can install a fuse in the shunt/fuse
location to limit the maximum sustained current supplied to the AP to prevent damage to the AP or to
the cable plant. Fuses of various amperage are available, and so you can select the appropriate fuse
rating depending on the configuration and operating voltage.

AC Power Supply

Non PoC versions of the AP come equipped with an AC power supply. The power supply is designed
to accept AC voltage from 100 V to 277 V RMS.
The following AC power cords are supported:

DC Interface

All versions of the AP have an externally accessible DC input connector. The DC input accepts voltages
in the 10 to 16V range. The power supplied should be 10 amp.
