AP-270 Series Outdoor Access Point

Installation Guide

0511511-05 | February 2014 1

The Aruba AP-274 and AP-275 are environmentally hardened, outdoor rated, dual-radio IEEE 802.11ac

wireless access points. These access points use MIMO (Multiple-in, Multiple-out) technology and other

high-throughput mode techniques to deliver high-performance, 802.11ac 2.4 GHz and 5 GHz functionality

while simultaneously supporting existing 802.11a/b/g/n wireless services. The AP-270 Series access point

works only in conjunction with an Aruba Controller.

USB Console Port

The USB Micro-B console port allows you to connect the AP to a terminal or a laptop for direct local

management. Use the included USB console cable to connect the AP. You can download the necessary

driver for USB-UART adapter from support.arubanetworks.com under the Tools & Resources tab.

Use the following setting to access the terminal:

Ethernet Ports

AP-270 Series is equipped with two10/100/1000Base-T (RJ-45) Gigabit Ethernet ports (WAN and LAN port)

for wired network connectivity. The WAN port supports 802.3at Power over Ethernet (PoE), accepting 48

VDC (nominal) as a standard defined Powered Device (PD) from a Power Sourcing Equipment (PSE) such

as a PoE midspan injector.

These ports have RJ-45 female connectors with the pin-outs shown in Figure 5.

Figure 5 Gigabit Ethernet Port Pin-Out

Reset Button

The reset button can be used to return the AP to factory default settings. To reset the AP:

1. Power off the AP.

2. Press and hold the reset button using a small, narrow object, such as a paperclip.

3. Power-on the AP without releasing the reset button. The system LED will flash within 5 seconds.

4. Release the reset button.

The system LED will flash again within 15 seconds indicating that the reset is completed. The AP will now

continue to boot with the factory default settings.

AC Power Interface

The AP-270 Series is capable of AC power in the range of 100 - 240 VAC. The power cord or power

connector kit is sold separately.

Grounding Point

Always remember to protect the AP by installing grounding lines. The ground connection must be complete

before connecting power to the AP enclosure.

External Antenna Connectors

The AP-274 is equipped with six external antenna connectors. The connectors are labeled 2G0, 2G1, 2G2,

5G0, 5G1 and 5G2, and correspond to 2.4/5Ghz radio chains 0,1, and 2.

Air Vent

The bottom of the AP-270 Series has an air vent to balance the pressure and humidity inside and outside the

AP. It also allows air exchange between the AP and the environment in a controlled way that doesn’t allow

water to get into the AP.

FCC Statement: Improper termination of access points installed in the United States configured to non-US model

controllers will be in violation of the FCC grant of equipment authorization. Any such willful or intentional violation

may result in a requirement by the FCC for immediate termination of operation and may be subject to forfeiture (47

CFR 1.80).

Pre-Installation Network Requirements

After WLAN planning is complete and the appropriate products and their placement have been determined,

the Aruba controller(s) must be installed and initial setup performed before the Aruba APs are deployed.

For initial setup of the controller, refer to the ArubaOS Quick Start Guide for the software version installed

on your controller.

Pre-Installation Checklist

Before installing your AP-275, be sure that you have the items listed below:

Gigabit Ethernet cable of required length

IEEE 802.3at compliant PoE source or AC power source

Aruba Mobility Controller configured and installed on the network

Layer 2/3 network connectivity to your AP

One of the following network services:

Aruba Discovery Protocol (ADP)

DNS server with an “A” record

DHCP Server with vendor specific options

Verifying Pre-Installation Connectivity

Before you install APs in a network environment, make sure that the APs will be able to locate and connect

to the controller when they are powered on.

Specifically, you must verify the following conditions:

When connected to the network, each AP is assigned a valid IP address.

APs can locate the controller.

EU Statement:

Aruba Networks, Inc. in compliance with governmental requirements, has designed the AP-270 Series such that

only authorized network administrators can change configuration settings. For more information about AP

configuration, refer to the ArubaOS Quick Start Guide and ArubaOS User Guide.

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.

AP-270 Series Outdoor Access Point | Installation Guide 9

Refer to the ArubaOS Quick Start Guide for instructions on locating and connecting to the controller.

Identifying Specific Installation Locations

You can mount the AP-270 Series access point on a wall or pole. Use the AP placement map generated by

Aruba’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. Examples of sources that degrade RF performance include:

Cement and brick

Objects that contain water

Metal

Microwave ovens

Wireless phones and headsets

Installing the AP

Using the Mounting Kits

The AP-270 Series can be installed on a wall or attached to a pole by using mounting kits. These mounting

kits are available as accessories and are sold separately:

Service to all Aruba products should be performed by trained service personnel only.

Mounting the AP to a Wall

1. Begin by marking the mounting points on the wall in the location you have selected.

a. Put the mounting bracket (included in the mount kit) on the installation position against the wall.

b. Using the mounting bracket as the template, mark four mounting points on the wall.

2. Use a drill to create four holes on the four markings you created in the previous step.

3. Insert a anchor bolt into each drilled hole. Anchor bolts are not included in the mount kit.

4. Place the mounting bracket over the anchor bolts and press the bracket against the wall.

5. Place the washers and nut onto the bolt’s threaded end and tighten the nut till the mounting bracket is

firmly attached to the wall as shown in Figure 12 or Figure 13.
