AP-220 Series Wireless Access Point
Installation Guide
The Aruba AP-224 and AP-225 wireless access points support the IEEE 802.11ac
standard for high-performance WLAN. This access point uses MIMO (Multiple-in,
Multiple-out) technology and other high-throughput mode techniques to deliver
high-performance, 802.11n 2.4 GHz and 802.11ac 5 GHz functionality while
simultaneously supporting existing legacy wireless services. The AP-220 Series
access point works only in conjunction with an Aruba Controller.
The Aruba AP-220 Series access point provides the following capabilities:
Wireless transceiver
Protocol-independent networking functionality
IEEE 802.11a/b/g/n/ac operation as a wireless access point
IEEE 802.11a/b/g/n/ac operation as a wireless air monitor
Compatibility with IEEE 802.3at PoE+ and 802.3af PoE
Central management configuration and upgrades with an Aruba Controller

LEDs
The AP-220 Series is equipped with five LEDs that indicate the status of the
various components of the AP.
External Antenna Connectors
The AP-224 is equipped with three external antenna connectors. The connectors
are labeled ANT0, ANT1, and ANT2, and correspond to radio chains 0, 1, and 2.

USB Interface
The AP-220 Series is equipped with a USB interface for connectivity with cellular
modems.
Console Port
The serial console port allows you to connect the AP to a serial terminal or a
laptop for direct local management. This port is an RJ-45 female connector with
the pinouts described in
Figure 4
. Connect it directly to a terminal or terminal
server using an Ethernet cable.

Ethernet Ports
AP-220 Series is equipped with two10/100/1000Base-T (RJ-45) auto-sensing, MDI/
MDX wired-network connectivity port. These ports support IEEE 802.3af and
802.3at Power over Ethernet (PoE) compliance, accepting 56VDC as a standard
defined Powered Device (PD) from a Power Sourcing Equipment (PSE) such as
a PoE midspan injector, or network infrastructure that supports PoE.
The 10/100/1000 Mbps Ethernet ports are on the bottom of the AP. These ports
have RJ-45 female connectors with the pin-outs shown in
Figure 5
.

Kensington Lock Slot
The AP-220 Series is equipped with a Kensington security slot for additional
security.
Reset Button
The reset button can be used to return the AP to factory default settings. To reset
the AP:
1. Power off the AP.
2. Press and hold the reset button using a small, narrow object, such as a
paperclip.
3. Power-on the AP without releasing the reset button. The power LED will
flash within 5 seconds.
4. Release the reset button.
The power LED will flash again within 15 seconds indicating that the reset is
completed. The AP will now continue to boot with the factory default settings.
DC Power Socket
If PoE is not available, an optional Aruba AP AC-DC adapter kit (sold separately)
can be used to power the AP-220 Series.
Additionally, a locally-sourced AC-to-DC adapter (or any DC source) can be used
to power this device, as long as it complies with all applicable local regulatory
requirements and the DC interface meets the following specifications:
12 VDC (+/- 5%)/18W
Center-positive 1.7/4.0 mm circular plug, 9.5 mm length
Before You Begin
Pre-Installation Network Requirements
After WLAN planning is complete and the appropriate products and their
placement have been determined, the Aruba controller(s) must be installed and
initial setup performed before the Aruba APs are deployed.
For initial setup of the controller, refer to the
ArubaOS Quick Start Guide
for
the software version installed on your controller.
AP Pre-Installation Checklist
Before installing your AP-220 Series AP, ensure that you have the following:
CAT5e or CAT6 UTP cable of required length
One of the following power sources:
IEEE 802.3at or 802.3af-compliant Power over Ethernet (PoE) source. The
POE source can be any power source equipment (PSE) controller or
midspan PSE device
Aruba AP AC-DC adapter kit (sold separately)
Aruba Controller provisioned on the network:
Layer 2/3 network connectivity to your access point
One of the following network services:
Aruba Discovery Protocol (ADP)
DNS server with an “A” record
DHCP Server with vendor-specific options
Summary of the Setup Process
Successful setup of an AP-220 Series access point consists of five tasks, which
must be performed in this order:
1. Verify pre-installation connectivity.
2. Identify the specific installation location for each AP.
3. Install each AP.
4. Verify post-installation connectivity.
5. Configure each AP.
Verifying Pre-Installation Connectivity
Before you install APs in a network environment, make sure that the APs are
able to locate and connect to the controller after power on.
Specifically, you must verify the following conditions:
When connected to the network, each AP is assigned a valid IP address
APs are able to locate the controller
Refer to the
ArubaOS Quick Start
Guide for instructions on locating and
connecting to the controller.
Identifying Specific Installation Locations
You can mount the AP-220 Series access point on a wall or on the ceiling. Use the
AP 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 AP 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
The AP-220 Series requires ArubaOS 6.3.0.0 or later.
Inform your supplier if there are any incorrect, missing, or damaged parts. If
possible, retain the carton, including the original packing materials. Use
these materials to repack and return the unit to the supplier if needed.

Aruba Networks, Inc., in compliance with governmental requirements, has
designed the AP-220 Series access points so that only authorized network
administrators can change the settings. For more information about AP
configuration, refer to the
ArubaOS Quick Start Guide and ArubaOS User
Guide
.
!
Access points are radio transmission devices and as such are subject to
governmental regulation. Network administrators responsible for the
configuration and operation of access points must comply with local
broadcast regulations. Specifically, access points must use channel
assignments appropriate to the location in which the access point will be
used.
