Dell PowerConnect W-AP120 Series AP
Installation Guide
The Dell W-AP120 series of wireless access points support the imminent IEEE 802.11n (currently draft 2.0)
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, pre-802.11n 2.4 GHz and 5 GHz
functionality while simultaneously supporting existing 802.11a/b/g wireless services. The W-AP120 series access
points are available in versions with single or dual radios and with integrated antennas or RP-SMA interfaces that
support detachable antennas. The W-AP120 series access points work only in conjunction with an Dell controller.
The Dell W-AP120 series access points provide the following capabilities:
Wireless transceiver
Protocol-independent networking functionality
IEEE 802.11a/b/g or 802.11n operation as a wireless access point
IEEE 802.11a/b/g or 802.11n operation as a wireless air monitor
Compatibility with IEEE 802.3af PoE as well as high power over Ethernet pre-standards
(PoE + / 802.3at)
Central management configuration and upgrades through an Dell controller
Upgrade of W-AP120 series a/b/g models to 802.11n (draft) compliance through a controller license

Page 2: Before You Begin
Before You Begin WLAN Planning Determine how many Dell APs are needed for your wireless network deployment and where they will be installed. You can easily accomplish this planning using Dell’s automated RF Plan site-survey software (available separately). This process is considered WLAN or RF planning and should have been completed during the master Dell controller installation and configuration. -

5. Configure each AP. Note: Dell, in compliance with governmental requirements, has designed the AP-120 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. -

4. Pushing toward the ceiling tile, rotate the AP clockwise until the device clicks into place on the ceiling tile rail. 5. On the W-AP121 or W-AP125, orient the antennas. For best results, rotate the antennas so that they are vertical (perpendicular to the body of the AP) (see Figure Dell PowerConnect W-AP120 Series AP | Installation Guide... -
Page 6: Connecting Required Cables
The RJ45 Ethernet ports (ENET0 and ENET1) support 100/1000Base-T auto-sensing MDI/MDX connections. Use these ports to connect the AP to a twisted pair Ethernet LAN segment or directly to an Dell controller. Use a 4- or 8-conductor, Category 5 UTP cable up to 100 m (325 feet) long. -
Page 7: Power Connection
The W-AP120 series AP has a single 5V DC power jack socket to support powering through an AC-to-DC mains electric power adapter. Note: If both POE and DC power are available, the AP uses POE, even when there is not enough POE voltage available to power the Dell PowerConnect W-AP120 Series AP | Installation Guide... -
Page 8: Connecting A Security Cable
Provisioning parameters are unique to each AP. These local AP parameters are initially configured on the controller which are then pushed out to the AP and stored on the AP itself. Dell recommends that provisioning settings be configured via the ArubaOS Web UI only. Refer to the ArubaOS User Guide for complete details. -
