AP-92 and AP-93 Wireless Access Point
Installation Guide
About the Aruba AP-92/AP-93
The Aruba AP-92 and AP-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 AP-92 and AP-93 access points work only in conjunction with an
Aruba Controller.
The Aruba AP-92/AP-93 access point provides the following capabilities:
z
Wireless transceiver
z
Protocol-independent networking functionality
z
IEEE 802.11a/b/g/n operation as a wireless access point
z
IEEE 802.11a/b/g/n operation as a wireless air monitor
z
Compatibility with IEEE 802.3af PoE
z
Central management configuration and upgrades through an Aruba
Controller

Ethernet Port
AP-92/AP-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 AP-92/AP-93.
External Antenna Connectors
The AP-92 is designed for use with external antennas. The AP-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 AP-92/AP-93 access point, be sure that you have the
following:
z
CAT5 UTP cable of required length
z
One of the following power sources:
IEEE 802.3af-compliant Power over Ethernet (PoE) source
Aruba AP AC-DC adapter kit (sold separately)
z
Aruba Controller provisioned on the network:
Layer 2/3 network connectivity to your access point
One of the following network services:
z
Aruba Discovery Protocol (ADP)
z
DNS server with an “A” record
z
DHCP Server with vendor-specific options
Summary of the Setup Process
Successful setup of an AP-92/AP-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:
z
When connected to the network, each AP is assigned a valid IP address
z
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-92/AP-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:
z
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.
z
Natural Items—Fish tanks, water fountains, ponds, and trees
z
Brick
RF reflectors include:
z
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.
z
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:
z
Microwave ovens and other 2.4 or 5 GHz objects (such as cordless phones)
z
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
).

Using the Integrated Ceiling Tile Rail Slots
The snap-in tile rail slots on the rear of the AP can be used to securely attach the
device directly to a 15/16" wide, standard ceiling tile rail.
1. Pull the necessary cables through a prepared hole in the ceiling tile near
where the AP will be placed.
2. If necessary, connect the console cable to the console port on the back of the
AP.
3. Hold the AP next to the ceiling tile rail with the ceiling tile rail mounting slots
at approximately a 30-degree angle to the ceiling tile rail (see
Figure 5
). Make
sure that any cable slack is above the ceiling tile.

4. Pushing toward the ceiling tile, rotate the AP clockwise until the device
clicks into place on the ceiling tile rail.
Connecting Required Cables
Install cables in accordance with all applicable local and national regulations
and practices.
Ethernet Ports
The RJ45 Ethernet port (ENET) supports 10/100/1000Base-T auto-sensing MDI/
MDX connections. Use these ports to connect the AP to a twisted pair Ethernet
