IAP-92 and IAP-93 Wireless Access Point
Installation Guide
About the Aruba IAP-92/IAP-93
The Aruba IAP-92 and IAP-93 are single-radio, dual-band wireless access points
that support the IEEE 802.11n standard for high-performance WLAN. These
access points use MIMO (Multiple-in, Multiple-out) technology and other high-
throughput mode techniques to deliver high-performance, 802.11n 2.4 GHz or 5
GHz functionality while simultaneously supporting existing 802.11a/b/g wireless
services. The IAP-92 and IAP-93 access points work only in conjunction with an
Aruba Controller.
The Aruba IAP-92/IAP-93 access point provides the following capabilities:
 Wireless transceiver
 Protocol-independent networking functionality
 IEEE 802.11a/b/g/n operation as a wireless access point
 IEEE 802.11a/b/g/n operation as a wireless air monitor
 Compatibility with IEEE 802.3af PoE
 Central management configuration and upgrades through an Aruba
Controller

Ethernet Port
IAP-92/IAP-93 is equipped with a single 10/100/1000Base-T (RJ-45) auto-sensing,
MDI/MDX wired-network connectivity port. This port supports IEEE 802.3af
Power over Ethernet (PoE) compliance, accepting 48VDC 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.
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-92/IAP-93.
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.
External Antenna Connectors
The IAP-92 is designed for use with external antennas. The IAP-93 is equipped
with internal antennas.
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 IAP-92/IAP-93 access point, be sure that you have the
following:
 CAT5 UTP cable of required length
 One of the following power sources:
 IEEE 802.3af-compliant Power over Ethernet (PoE) source
 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 IAP-92/IAP-93 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 IAP-92/IAP-93 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.
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 AP between two air conditioning/heating ducts. Make sure
that APs 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
Installing the AP
Using the Integrated Wall-Mounting Slots
The keyhole-shaped slots on the back of the AP can be used to attach the device
upright to an indoor wall or shelf. When you choose the mounting location, allow
additional space at the right of the unit for cables.
1. Since the ports are on the back of the device, make sure that you mount the
AP is such a way that there is a clear path to the Ethernet port, such as a pre-
drilled hole in the mounting surface.
2. At the mounting location, install two screw on the wall or shelf, 1 7/8 inches
(4.7 cm) apart. If you are attaching the device to drywall, Aruba recommends
using appropriate wall anchors (not included).
3. Align the mounting slots on the rear of the AP over the screws and slide the
unit into place (see Figure 4).

Access points are radio transmission devices and as such are subject to
governmental regulation. Network administrators responsible for the con-
figuration 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.
