Dell PowerConnect W-AP175 Outdoor Access Point
Installation Guide
The Dell PowerConnect W-AP175 is a resilient, environmentally hardened, outdoor rated, dual-radio, dual-band
IEEE 802.11 a/b/g/n wireless access point. This outdoor access point is part of Dell's comprehensive wireless
network solution. The W-AP175 works only in conjunction with an Dell PowerConnect W-Series controller and
each AP can be centrally managed, configured, and upgraded through the controller.
NOTE: The W-AP175P requires ArubaOS 5.0.2.1 or later. The W-AP175AC and W-AP175DC require ArubaOS 6.1.2.3 or later.
There are three versions of the W-AP175, which mainly differ in the way they receive power.
W-AP175P: PoE+ powered (802.3at)
W-AP175AC: AC powered (100-240 V AC)
W-AP175DC: DC powered (12-48 V DC)
NOTE: The W-AP175AC/DC can function as a Power Sourcing Equipment (PSE) device by providing power through its ethernet
port in compliance with the IEEE 802.3af standard.

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. Dell PowerConnect W-AP175 Outdoor Access Point | Installation Guide... -
Page 3: Antenna Interface
The interfaces are grouped into diversity pairs, one pair is marked R0 (Radio 0) and the other pair marked as R1 (Radio 1). R0 supports the 5 GHz frequency band and R1 supports the 2.4 GHz radio band. Dell PowerConnect W-AP175 Outdoor Access Point | Installation Guide... -
Page 4: Power Interface
Always remember to protect your W-AP175 by installing grounding lines. The ground connection must be complete before connecting power to the W-AP175 enclosure. Ensure that the resistance is less than 5 ohm between the ground termination point and the grounding tier.

Page 7: Outdoor Planning And Deployment Considerations
Maximum data rate: Four lit LEDs Outdoor Planning and Deployment Considerations Prior to deploying an outdoor wireless network, the environment must be evaluated to plan for a successful Dell WLAN deployment. Successfully evaluating the environment enables the proper selection of Dell APs and antennas and assists in the determination of their placement for optimal RF coverage. -

Avoid any partial line of sight between the antennas Be cautious of trees or other foliage that may be near the path, or may grow and obstruct the path. Dell PowerConnect W-AP175 Outdoor Access Point | Installation Guide... -
Page 9: Antenna Height
NOTE: To avoid any obstruction along the path, the height of the object must be added to the minimum clearance required for a clear radio line of sight. Consider the following simple example, illustrated in Figure Dell PowerConnect W-AP175 Outdoor Access Point | Installation Guide... -
Page 10: Antenna Position And Orientation
Always use a channel frequency that is furthest away from another signal. If radio interference is still a problem with your wireless bridge or mesh link, changing the antenna direction may improve the situation. Dell PowerConnect W-AP175 Outdoor Access Point | Installation Guide... -
Page 11: Weather Conditions
CAUTION: A Dell Lightning Arrestor, AP-LAR-1, must be installed on each antenna port for protection against lightning induced surges. Failure to use an AP-LAR-1 can void the warranty of an Dell outdoor AP model and renders the AP susceptible to failure from lightning induced surges Rain: The wireless bridge or mesh link is weatherproofed against rain. -

7). The same materials are needed for weatherproofing both types of connections but the procedure is slightly different.

Proper weatherproofing is not a fast process. Set aside ample time to complete the steps outlined below. When wrapping, make the each layer of tape as flat as possible. Wrinkles and folds in the tape create places for water and moisture to gather. Dell PowerConnect W-AP175 Outdoor Access Point | Installation Guide... - Page 15 5.
