6 Aruba 303H Series Hospitality Access Point | Installation Guide
Power Supply
The AP-303H access point has a single 48V DC power connector to
support AC-to-DC power using an AP-AC-48V36C power adapter (sold separately). The power connector port is
located on the side of the device, as shown in Figure 6.
The AP-303H access point supports both PoE-in and PoE-out functionality.
The PoE-in (PoE-PD) allows the E0 port to draw power from an 802.3at (preferred) source, or an 802.3af
(optional) source.
When powered by an 802.3at or DC power source, the PoE-out (PoE-PSE) functionality is enabled on port E3,
supplying a maximum output of 15W to a wired device.
Refer to Table 4 for power output details. PoE-PSE and USB settings can be enabled/disabled through the
software’s WebUI and CLI.
When both DC and PoE power are simultaneously available, the access point will default to using DC power,
while continuing to draw a minimal current from the PoE source. If DC power source is removed, the access
point will begin drawing power from the PoE source, allowing for a hitless fail-over when switching between
power sources.
Before You Begin
Refer to the sections below before beginning the installation process.
Pre-Installation Checklist
Before installing the AP-303H access point, be sure that you have the following:
Pre-installed wall box
Cat5E UTP cable with network access installed in the wall box
One of the following power sources:
IEEE 802.3af/at-compliant Power over Ethernet (PoE) source
Aruba AP AC-DC adapter kit (sold separately)
One of the following network services:
Aruba Discovery Protocol (ADP)
DNS server with an “A” record
DHCP Server with vendor-specific options
Identifying Specific Installation Locations
When installing the AP-303H access point must be secured to an Aruba-approved wall or to a desk mount kit.
This access point should be oriented vertically, with Ethernet ports facing downward to facilitate maximum
antenna gain. 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 be accounted for during the
planning phase and adjusted for in RF plan.

This device must be professionally installed and serviced by a trained ACMP or similar Aruba-certified
technician.The installer is responsible for securing the access point onto the ceiling tile rail in accordance with the
steps below. Failure to properly install this product may result in physical injury and/or damage to property.
Tous les points d’accès Aruba doivent être installés professionnellement par un Professionnel en mobilité certifié
par Aruba (ACMP). Il incombe au technicien d’installation de veiller à ce qu’une borne de raccordement à la terre
conforme avec tous les codes électriques nationaux applicables puisse être utilisée.
This device in compliance with governmental requirements, and is designed the so that only authorized network
administrators can change the settings. For more information about access point configuration, refer to the
ArubaOS Quick Start Guide and ArubaOS User Guide.
