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-277 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 3.

Figure 3 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-277 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.

CAUTION

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, 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.

CAUTION

EU Statement:

Aruba Networks, Inc. in compliance with governmental requirements, has designed the AP-277 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.

CAUTION

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.

APs can locate the controller.

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

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 routers and antennas and assists in the determination of their placement for

optimal RF coverage. This process is considered WLAN or RF planning and Aruba’s system engineers

can assist in the outdoor planning process.

For WLAN systems being installed outdoors in the USA, the following requirements must be met.

1. Systems must be professionally installed by a qualified engineer familiar with WLAN, including

Aruba trained partners and resellers.

2. Operation in the 5600-5650-MHz band is prohibited.

3. When within 35 km distance of a TDWR, the center frequency of the WLAN must be separated

from the TDWR center frequency by 30 MHz.

a. If the radar is operating from 5600-5610 MHz, disable the use of channel 116 (5580 MHz).

b. If the radar is operating from 5630-5650 MHz, disable the use of channel 132 (5660 MHz).

For TWDR locations in the US please refer to www.wispa.org/tdwr-locations-and-frequencies.

Identifying Specific Installation Locations

You can mount the AP-277 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

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

Using the AP-270-MNT-H1 Mounting Kit

The AP-277 access point can be installed on a wall or attached to a pole by using AP-270-MNT-H1

mounting kit.

Mounting the AP-277 Access Point to a Wall

1. Use the mounting template provided in the AP-270-MNT-H1 mounting kit package to mark the

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 an anchor bolt into each drilled hole. Anchor bolts are not included in the mounting kit

package.

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 until the mounting

bracket is firmly attached to the wall as shown in Figure 6.

Figure 6 Attaching the Mounting Bracket to a wall

6. Use the M10x30 screw (with washer) and M10 nut included in the package to attach the mounting

holder to the mounting bracket as shown in Figure 7.

The AP-277 access point does not ship with any mounting kit. The AP-270-MNT-H1 mounting kit is available as

accessories and must be ordered separately.

For details on AP-270-MNT-H1, please refer to the AP-270-MNT-H1 Installation Guide.

10 AP-277 Outdoor Access Point | Installation Guide

Figure 9 Attaching the AP to the Mounting Holder (Completed)

The inclination of the AP (mounted to the mounting holder) can be adjusted up to +/-45 degrees by

inserting the M6x20 screw (included in the package) into the different holes on the mounting holder.

8. Use the cable tie to fasten the cables on the bracket.

Mounting the AP to a Pole

1. Begin by attaching the mounting bracket to the pole as shown in Figure 10.

a. Pass a hose clamp through the two slots on the mounting bracket, attach the mounting bracket

to the pole and tighten the clamp using a screw driver to twist its screw head.

b. Use another hose clamp through the other two slots on the mounting bracket and tighten the

clamp.
