Aruba AP-175 Outdoor Access Point

Installation Guide

0510795-01 | September 2010 1

The Aruba AP-175 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 Aruba’s comprehensive wireless

network solution. The AP-175 works only in conjunction with an Aruba controller and each AP can be

centrally managed, configured, and upgraded through the controller.

There are three versions of the AP-175, which mainly differ in the way they receive power.

z AP-175P: PoE+ powered (802.3at)

z AP-175AC: AC powered (100 - 240 VAC)

z AP-175DC: DC powered (12 - 48 VDC)

Guide Overview

z "AP-175 Hardware Overview" on page2 provides a detailed hardware overview of the three AP-175

models.

z "Outdoor Planning and Deployment Considerations" on page5 provides key questions to ask and items

to consider when deploying an outdoor wireless network.

z "Installing the AP-175" on page9 describes the multi-step process for a successful installation and

deployment of an AP-175.

z "Safety and Regulatory Compliance" on page15 provides an overview of safety and regulatory

compliance information.

AP-175 Operations

z Wireless access point (IEEE 802.11 a/b/g/n)

z Wireless air monitor (IEEE 802.11 a/b/g/n)

z Enterprise mesh point

z Enterprise mesh portal

z Protocol-independent networking functionality

z AP-175P: IEEE 802.3at Power over Ethernet+ (PoE+) compatible

z AP-175AC and AP-175DC: IEEE 802.3af Power Sourcing Equipment (PSE) device

NOTE

The AP-175AC/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.

Select the correct antenna type to support the required frequency band (2.4 or 5 GHz) and the desired coverage pattern. The AP-175 is equipped with four, female N-type antenna interfaces; two on the top of the AP and two on the bottom. The interfaces are grouped into diversity pairs, one pair is marked R0 (Radio 0) and the other pair marked as R1 (Radio 1).

AP-175-IG-Rev01.fm Page 5 Friday, September 17, 2010 4:27 PM Outdoor Planning and Deployment Considerations Prior to deploying an outdoor wireless network, the environment must be evaluated to plan for a successful Aruba WLAN deployment. Successfully evaluating the environment enables the proper selection of Aruba APs and antennas and assists in the determination of their placement for optimal RF coverage.

AP-175-IG-Rev01.fm Page 9 Friday, September 17, 2010 4:27 PM Ethernet Cabling When a suitable antenna location has been determined, you must plan a cable route from the wireless bridge or mesh link outdoors to a suitable power and/or network source. Consider these points: z The Ethernet cable length should never be longer than 90 m (295 ft). z Determine a building entry point for the cable (if applicable).
