Dell PowerConnect W-AP90 Series Access Point
Installation Guide

 

About the Dell W-AP90 Series

The Dell W-AP90 Series APs 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 W-AP90 Series access points work only in conjunction with an Dell Controller.

The Dell W-AP90 Series 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 Dell Controller

Use the console port to connect to a terminal for direct local management.

Ethernet Port

The W-AP90 Series 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 Dell AP AC-DC adapter kit (sold separately) can 
be used to power the AP. 

External Antenna Connectors

The W-AP92 is designed for use with external antennas. The W-AP93 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 Dell controller(s) must be installed and initial setup 
performed before the Dell 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 W-AP90 Series 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

„

Dell AP AC-DC adapter kit (sold separately)

z

Dell Controller provisioned on the network:

„

Layer 2/3 network connectivity to your access point

One of the following network services:

z

Dell 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 W-AP90 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:

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 W-AP90 Series access point on a wall or on the ceiling. Use the 
AP placement map generated by Dell’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, Dell 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.

Note:  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.

AP Pre-Installation 

Checklist

 before you attempt to set up and install an W-AP90 Series.

Note:  Dell, in compliance with governmental requirements, has designed the W-
AP90 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

.

Caution:  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.

Caution:  Installation and service of Dell Networks products should be performed 
by Professional Installers. Additional antenna and transmit power information for 
Professional Installers can be found at 

https://support.arubanetworks.com

.

Note:  If you are installing an W-AP92, be sure to attach the antennas before 
mounting the AP.

Caution:  Make sure the AP fits securely on the ceiling tile rail when hanging the 
device from the ceiling; poor installation could cause it to fall.
