Introduction
The small form factor Wireless Switch Dualband Access Point DWL-8220AP increases
wireless LAN secure mobility, supports dualband WLAN connectivity, and provides client
access to the functions of the AirPremier® MobileLAN™ DWS-1008 Wireless Switch. Each
DWL-8220AP continually tunes itself for optimal RF channel and transmit power to provide
all mobile clients with the best wireless signal in both the 802.11a and 802.11g bands.
Sensitive Information Not Stored Locally
Individual DWL-8220APs have no local storing of any data so they can be safely installed
in unsecured areas without fear of hacking or theft. The DWS-1008 Wireless Switch is the
hardware that stores vital network and user information in plain site and is typically stored in
a secure location. DWL-8220APs can link to DWS-1008 directly or through the existing wired
network - even across Layer 3 boundaries - and receive Power over Ethernet (PoE) from
directly connected DWS-1008 or third-party PoE injectors.
Self Configuration and Easy Installation
The DWS-1008 Wireless Switch automatically configures every connected DWL-8220AP so
that no configuration is necessary during installation. If a DWL-8220AP needs to be replaced,
the replacement DWL-8220AP automatically inherits the same configuration, making the
replacement process analogous to changing a light bulb.
These plenum-rated DWL-8220APs intentionally resemble smoke detectors to minimize
visibility. With no protruding antennas and no obvious hallmarks of an AP, DWL-8220APs are
less likely to be tampered with. For added protection, all APs feature a built-in Kensington
security lock interface.
Continuous Channel Scanning To Prevent Rogue APs
DWL-8220APs play a key role in rogue detection – they continuously scan both bands
and their associated channels to root out rogues while simultaneously providing wireless
connectivity to mobile clients. If a rogue is detected, the closest DWL-8220AP can launch
RF Countermeasures by spoofing 802.11 control messages. This prevents clients from
communicating, associating and authenticating with a rogue.
Increases User Productivity
For important wireless transmissions such as VoIP related applications, DWL-8220APs also
deliver critical user-based services, such as prioritized delivery of voice traffic. Supporting
multiple queues per user, DWL-8220APs always prioritize expedited traffic such as voice
calls.
Introduction
* Maximum wireless signal rate based on IEEE Standard 802.11a/11b/11g specifications. Actual data throughput
will vary. Network conditions and environmental factors, including volume of network traffic, building materials
and construction, and network overhead, lower actual data throughput rate.

DWL-8220AP User’s Manual
D-Link Systems, Inc.
The DWL-8220AP access point (AP) provides IEEE 802.11 wireless access to the network.
It is designed for use with the D-Link DWS-1008 wireless switch. The access point requires
hardware installation only. All configuration for the access point takes place on the switch.
The DWL-8220AP has one 802.11a radio and one 802.11b/g radio. Both radios have
internal diversity omnidirectional antennas. In addition, both radios have separate jacks for
attachment of optional external sectorized or directional antennas. The antennas must be
ordered separately.
Note: Installation must be performed by qualified service personnel only. Read and follow all
warning notices and instructions marked on the product or included in the documentation.
The access point radios are disabled by default and can be enabled only by a system
administrator using the DWS-1008 wireless switch.
Ethernet Ports
The DWL-8220AP has two RJ-45 ports. Each port provides a 10/100BASE-TX Ethernet
connection to a DWS-1008 switch. The connection can be direct to a DWS-1008 switch or
indirect through an intermediate Layer 2 or Layer 3 network.
The access point receives power and data through the RJ-45 ports. Use a straight-through
Category 5 (CAT5) Ethernet cable to connect an AP to a DWS-1008 switch or other device
in the network. The DWL-8220AP supports 802.3af, and also can receive PoE from D-Link
switches and D-Link-approved power injectors.
The two RJ-45 ports support dual-homed configurations for redundancy. The DWL-8220AP
uses only one link for booting, configuration, and data transfer. If the link becomes unavailable,
the AP can reboot using the other link. The ports are identical except for logical numbering (1
or 2). You can use either port to connect an AP access point to a DWS-1008 switch. However,
an AP always attempts to boot on port 1 first. Only if the boot attempt on port 1 fails does the
AP attempt to boot on port 2. If one port becomes unavailable, the other port can provide full
power to the AP.
Note: Access points do not support daisy-chain configurations. Do not connect the access
point to another access point.

Kensington Security Slot
The DWL-8220AP has a slot for attachment of a Kensington security cable. The cable is not
included with the AP but can be ordered separately.
Connection Options
You can connect an access point directly to a DWS-1008 switch port or indirectly to DWS-1008
switches through an intermediate Layer 2 or Layer 3 network. In either case, use Category 5
(CAT5) cable with straight-through signaling for each AP connection.
You also can provide data link redundancy by connecting both of its ports directly to
DWS-1008 switch ports or indirectly to DWS-1008 switches through the network. You
can provide DWS-1008 management redundancy even on a single AP Ethernet port by
connecting the AP indirectly to multiple DWS-1008 switches through an intermediate Layer
2 or Layer 3 network.
Note: Install the CAT5 cables for the access point at the installation site before installing the
access point itself. During installation, you will insert the CAT5 cable(s) into the AP port(s)
before attaching the access point to the bracket.

Installation Overview
Installation Overview
DWL-8220AP Mounting Options
You can mount a DWL-8220AP access point on any of the following types of surfaces:
• Suspended T-bar ceiling
• Junction box
• Solid surface wall or ceiling
• Tabletop
Note: The solid surface mounting option requires CAT5 cable that does not have strain relief.
The other mounting options can use CAT5 cable with or without strain relief.
Wall Installation Recommendations
If you plan to install an AP on a partial wall or other vertical surface, orient the top of the
access point (the side with the LEDs) toward the intended coverage area. The radio antennas
transmit through the top of the access point but not through the bottom (where the bracket
is). This recommendation does not apply if you plan to use external antennas. You can orient
the antennas independently of the AP itself. Orient an external antenna to face the intended
coverage area.
DWS-1008 Wireless Switch Recommendation
D-Link recommends that you install and configure the DWS-1008 switch before installing
an access point. If the switch is already installed and configured for the access point(s), you
can immediately verify the cable connection(s) when you plug the cable(s) into the access
point.
Warning: The DWL-8220AP is designed to receive power only from an 802.3af-compliant
source, a D-Link DWS-1008 wireless switch, or a D-Link-approved power injector. Connecting
an access point to a Power over Ethernet (PoE) device that is not approved by D-Link can
damage the equipment.
Radio Frequency Exposure
Federal Communications Commission (FCC) Docket 96-8 for Spread Spectrum Transmitters
specifies a safety standard for human exposure to radio frequency electromagnetic energy
emitted by FCC-certified equipment. When used with the proper antennas (shipped in the
product), D-Link access point products meet the uncontrolled environmental limits found
in OET-65 and ANSI C95.1-1991. Proper installation of the DWL-8220AP access point
according to the instructions in this manual will result in user exposure that is below the FCC
recommended limits.
Warning: In the U.S., locate the access point and any externally attached antennas a
minimum of 20 cm (7.9 inches) away from people. This safety warning conforms with FCC
radio frequency exposure limits for dipole antennas such as those used in the DWL-8220AP
access point.

CAT5 cable with straight-through signaling must be installed at the site before you install an
access point. A single connection requires one cable. A dual-homed connection requires two
cables. The table below lists the pin signals for 10/100 Ethernet straight-through wiring. Pins
4, 5, 7, and 8 are used when D-Link Power over Ethernet (PoE) is enabled on the port. RD
means Receive Data and TD means Transmit Data.
Mounting a DWL-8220AP access point on a solid surface requires CAT5 cable that does
not have strain relief. For installation on all other surfaces, you can use CAT5 cable with or
without strain relief.
