remaining PoE source. When power is combined from both PoE sources, an approximately equivalent amount of
power is drawn from each port, unless either source is hitting maximum capacity.

Before You Begin
Refer to the sections below before beginning the installation process.
Pre-Installation Checklist
Before installing your Aruba 555 access point, be sure that you have the following (not included with the AP):
 A mount kit compatible with the AP and mount surface
 A Cat5E or better UTP cable with network access
Optional items:
 A compatible 48V AC-to-DC power adapter with cord
 A compatible POE midspan injector with power cord
 A compatible snap-on front cover (for easy aesthetic customization)
 An AP-CBL-SERU console cable
Also, make sure at least one of the following network services is supported:
 Aruba Discovery Protocol (ADP)
 DNS server with an “A” record
 DHCP Server with vendor-specific options
Identifying Specific Installation Locations
Use the access point placement map generated by Aruba 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 be accounted for during the planning phase and
adjusted for in RF plan.
