AP-270 Series Outdoor Access Point
Installation Guide
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.

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.

Reset Button
The reset button can be used to return the AP to factory default settings. To reset the AP:
AP-270 Series Outdoor Access Point | Installation Guide 5
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.

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.
Before You Begin
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
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.
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.
