Power

The E0 and E1 port support PoE-in, allowing one port to draw power from an

802.3at (recommended) or an 802.3af source. When both PoE and DC power
sources are available, the access point will default to using the DC power source.

If PoE is not available, the 320 Series has a single 12V/30W DC power jack socket
to support the AP-AC-12V30UN AC-to-DC adapter kit (sold separately).

Power Modes

The 320 Series can operate in two power modes. The modes are not configurable
and are determined by the access point based on the amount of power available.

The 320 Series Wireless Access Points operate without restrictions when
powered by a DC or 802.3at PoE source. When powered by an 802.3af PoE
source, the following restrictions apply:

 Second Ethernet port disabled
 USB interface disabled
 2.4 GHz in 1x1:1 mode

Aruba 320 Series Wireless

Identifying Specific Installation Locations

You can mount the 320 Series access point on a wall or on the ceiling. Use the
access point placement map generated by Aruba’s RF Plan software application
to determine the proper installation location(s). Each location should be as close
as possible to the center of the intended coverage area and should be free from
obstructions or obvious sources of interference. These RF absorbers/reflectors/
interference sources will impact RF propagation and should have been
accounted for during the planning phase and adjusted for in RF plan.

Identifying Known RF Absorbers/Reflectors/Interference
Sources

Identifying known RF absorbers, reflectors, and interference sources while in the
field during the installation phase is critical. Make sure that these sources are
taken into consideration when you attach an access point to its fixed location.
Examples of sources that degrade RF performance include:

 Cement and brick
 Objects that contain water
 Metal
 Microwave ovens
 Wireless phones and headsets
