Aruba 555 Access Point
Installation Guide
XXX-IG-0X | Month Year 1
The Aruba 555 Access Point (AP-555) is a higher-performance, multi-radio wireless device that can be deployed
in either controller-based (ArubaOS) or controllerless (InstantOS) network environments. This access point
delivers high-performance concurrent 2.4 GHz 802.11ax Wi-Fi (Wi-Fi 6) functionality with 4x4 MIMO radio and 5
GHz 802.11ax Wi-Fi (Wi-Fi 6) functionality with 8x8 MIMO radio, while also supporting legacy 802.11 a/b/g/n/ac
wireless services.
Wired Ethernet ports located on the back of this access point are used to connect the device to the wired
networking infrastructure (wired speeds up to 5 Gbps are supported by both ports) and to provide POE power
(802.3at class 4 or 802.3bt class 5) to the device. In addition to both Wi-Fi radios, this AP also incorporates a
Bluetooth Low Energy (BLE) and Zigbee radio, supporting a variety of use-cases and services, such as locationing
and IoT.
Hardware Overview
The following sections outline the hardware components of the AP-555.

Bluetooth Low Energy Radios
AP-555 is equipped with an integrated BLE radio that provides the following capabilities:
location beacon applications
wireless console access
IoT gateway applications
Console Port
The 5-pin Micro-B connector is located on the back of this device. Use the proprietary AP-CBL-SERU cable for
direct management of this device when connected to a laptop or serial console (a standard USB cable cannot be
used for this interface). For pin-out details, refer to Figure 4.
Figure 4 Micro-B Port Pin-out
Ethernet Ports
The Aruba 555 access point is equipped with two active Ethernet ports (Eth0 and Eth1), shown in Figure 3. Both
ports are 100/1000/2500/5000 Base-T, auto-sensing MDI/MDX, which supports uplink connectivity when linked
by an Ethernet cable. Refer to Figure 5 for a detailed port pin-out.
This device is intended for indoor use in professional healthcare facilities.

Kensington Lock Slot
The 555 access points are equipped with a Kensington lock slot for additional physical security.
USB Interface
The top of this access point is equipped with a USB-A port that is compatible with cellular modems. When active,
this port can supply up to 5W/1A to a connected device.
Figure 6 AP-555 (USB)
Reset Button
The reset button located on the bottom of the device can be used to reset the access point to factory default
settings or turn off/on the LED display.
Use one of the following methods to reset the access point to factory default settings:
To reset during normal operation:
1.Hold the reset button for more than 10 seconds while the access point is running.
2.Release the reset button.
To reset during power up, hold the reset button while the access point is powering up.
The system status LED will flash again within 15 seconds indicating that the reset is completed. The access
point will now continue to boot with the factory default settings.
To toggle the LED display between Off and Blinking:
During the normal operation of the access point, shortly press and release the reset button using a small,
narrow object, such as a paperclip.
Power
Both ethernet ports support PoE-in (AP is a PoE-PD device), allowing the device to draw power from compliant
PoE power sources. If PoE is not available, the access point has a single 48V DC power import to support the AP-
AC-48V36C AC-to-DC power adapter kit (sold separately). When both PoE and DC power sources are available,
the DC power source takes precedence. In that case, the access point simultaneously draws a minimal current
from the PoE source(s). In the event that the DC source fails, the access point switches to the PoE source(s).
If the 555 access point is powered by both PoE ports simultaneously, it can combine power from both sources in
either shared or prioritized mode. When Eth0 is prioritized, the access point simultaneously draws a minimal
current from the Eth1 source. In the event that the prioritized port fails, the access point switches to the

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.

Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in
improper operation. If such use is necessary, this equipment and the other equipment should be observed to
verify that they are operating normally.

phase is critical. Make sure that these sources are taken into consideration when you attach an access point to its
fixed location.
RF absorbers include:
Cement/concrete—Old concrete has high levels of water dissipation, which dries out the concrete, allowing
for potential RF propagation. New concrete has high levels of water concentration in the concrete, blocking
RF signals.
Natural Items—Fish tanks, water fountains, ponds, and trees
Brick
RF reflectors include:
Metal Objects—Metal pans between floors, rebar, fire doors, air conditioning/heating ducts, mesh windows,
blinds, chain link fences (depending on aperture size), refrigerators, racks, shelves, and filing cabinets.
Do not place an access point between two air conditioning/heating ducts. Make sure that access points are
placed below ducts to avoid RF disturbances.
RF interference sources include:
Microwave ovens and other 2.4 or 5 GHz objects (such as cordless phones)
Cordless headset such as those used in call centers or lunch rooms
