Aruba Networks IAP-220 Series Installation Manual

IAP-220 Series Instant Access Point
Installation Guide
The Aruba IAP-224 and IAP-225 Instant 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 IAP-220 Series access point works only in conjunction with a virtual
controller.
The Aruba IAP-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

The IAP-220 Series requires Aruba Instant 4.0 or later.

USB Interface
The IAP-220 Series is equipped with a USB interface for connectivity with
cellular modems.
The USB interface is disabled when the IAP-220 Series is powered from
802.3af PoE.
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
IAP-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 48 VDC (nominal)
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.
When operating on 802.3af, only the port connected to power is
usable. For example, if the source of power is connected to ENET
0, ENET 1 will not work.
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 IAP-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 IAP-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
Power Modes
The IAP-220 Series can operate in two power modes. The AP's mode is not
configurable and is determined by the AP based on the amount of power
available. The two modes are:
 Full Power: The AP is receiving power from an 802.3at PoE source or is
powered using the optional AC-DC adapter kit. In this mode, all AP
functionality is available.
PoE Power Saving: The AP is receiving power from an 802.3af PoE source. In

this mode, the AP has somewhat reduced functionality: the second Ethernet
port is disabled, the USB port is disabled, and the AP operates in 1x3 RF
chain mode for 2.4 GHz (two transmit chains disabled). The 5 GHz radio
operates without restrictions.
Before You Begin
FCC Statement: Improper termination of access points installed in the
United States (non-US model Regulatory Domain model/s) will be in
!
violation of the FCC grant of equipment authorization. Any such willful or
intentional violation may result in a requirement by the FCC for immediate
termination of operation and may be subject to forfeiture (47 CFR 1.80).

AP Pre-Installation Checklist
Before installing your IAP-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 midspan power source equipment (PSE) device
 Aruba AP AC-DC adapter kit (sold separately)
Summary of the Setup Process
Successful setup of an IAP-220 Series access point consists of four tasks, which
must be performed in this order:
1. Identify the specific installation location for each AP.
2. Install each AP.
3. Verify post-installation connectivity.
4. Configure the virtual controller. Refer to the Aruba Instant Quick Start
Guide.
Aruba Networks, Inc., in compliance with governmental requirements, has
designed the IAP-220 Series access points so that only authorized network
administrators can change the settings. For more information about AP
configuration, refer to the Aruba Instant Quick Start Guide and Aruba
Instant 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.
Identifying Specific Installation Locations
You can mount the IAP-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
Installing the AP
Service to all Aruba Networks products should be performed by trained
service personnel only.
Using the Ceiling Rail Adapter
The IAP-220 Series ships with two ceiling rail adapters for 9/16" and 15/16"
ceiling rails. Additional wall mount adapters amd ceiling rail adapters for other
rail styles are available as accessory kits.
Make sure the AP fits securely on the ceiling tile rail when hanging
!
the device from the ceiling, because poor installation could cause it
to fall onto people or equipment.
1. Pull the necessary cables through a prepared hole in the ceiling tile near
where the AP will be placed.
2. Place the adapter against the back of the AP with the adapter at an angle of
approximately 30 degrees to the tabs (see Figure 6).
3. Twist the adapter clockwise until it snaps into place in the tabs (see
6).
