Ethernet Ports

228 Series is equipped with two10/100/1000Base-T (RJ-45) Gigabit Ethernet ports (E0/POE and E1) for

wired network connectivity. The E0/POE 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.

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).

Aruba 228 Series Wireless Access Points | Installation Guide 5

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

For AP-228 only:

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

6Aruba 228 Series Wireless Access Points | Installation Guide

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.

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

Identifying Specific Installation Locations

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 AP-220-MNT-W1 Mount Kit

The 228 Series access point can be installed on a wall by using AP-220-MNT-W1 mount kit.

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.

The instructions for this section are applicable to the AP-228 only.

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

The 228 Series access point does not ship with any mount kit. The AP-220-MNT-W1 mount kit is available as

accessories and must be ordered separately.

Aruba 228 Series Wireless Access Points | Installation Guide 7

1. Begin by attaching the wall mount adapter to the wall.

a. Install any necessary wall anchors. Wall anchors are not included in this kit.

b. Align the screw holes in the mounting bracket with the previously installed anchors or

demarcated screw points.

c. Insert the screws to secure the mounting bracket. Screws are not included in this kit.

2. Attach necessary cables and/or antennas to the AP.

3. Attach the AP to the secured mounting adapter as shown in Figure 7.

a. Align the AP with a mounting adapter, placing the AP so that it’s mounting tabs are at an angle

of approximately 30 degrees to the adapter.

4. Pushing toward the wall, rotate the AP clockwise until it clicks into place (see Figure 7).

For details on AP-220-MNT-W1, please refer to the AP-220-MNT-W1 Installation Guide.

Grounding the AP

The grounding must be completed before powering up the AP. The grounding wire should be #8

AWG.

1. Peel the cover of one end of the grounding wire and place the bare grounding wire into the

included copper lug, and press firmly with the crimping pliers.

2. Fasten the copper lug to the grounding hole on the AP with the included M4 x8 screw.

Connecting the Ethernet Cable

To connect the Ethernet cable to the AP, perform the following steps using the cable glands that ships

with your AP.

WARNING

Failure to use the included Ethernet cable glands can lead to connectivity and POE issues.

Aruba 228 Series Wireless Access Points | Installation Guide 9

Figure 9 Installing a Cable Gland

1. Slide the sealing nut over the cable (without the RJ45 connector attached to the end).

2. Slide the clamping ring over the cable.

3. Using a crimping tool, attach the shielded RJ45 connector to the end of the cable.

4. Remove the weatherproof cap on the Ethernet port.

5. Insert the RJ45 connector to the Ethernet port.

6. Screw the clamping ring onto the Ethernet port.

7. Screw the sealing nut onto the clamping ring.

Verifying Post-Installation Connectivity

The integrated LEDs on the AP can be used to verify that the AP is receiving power and initializing

successfully (see Table 1 and Table 2). Refer to the ArubaOS Quick Start Guide for further details on

verifying post-installation network connectivity.

Configuring the AP

AP Provisioning/Reprovisioning

Provisioning parameters are unique to each AP. These local AP parameters are initially configured on

the controller which are then pushed out to the AP and stored on the AP itself. Aruba recommends

that provisioning settings be configured via the ArubaOS Web UI only. Refer to the ArubaOS User

Guide for complete details.

AP Configuration

Configuration parameters are network or controller specific and are configured and stored on the

controller. Network configuration settings are pushed out to the AP(s) but remain stored on the

controller.

Configuration settings can be configured via the ArubaOS Web UI or ArubaOS CLI. Refer to the

ArubaOS User Guide for complete details.

The cable is not included and must be purchased separately. Purchase a suitable UV-resistant, outdoor rated,

CAT 5E or better RJ45 cable for use with the AP.

Sealing Nut Clamping Ring CAT 5E or Better Cable

Seals

The seals inside the clamping ring by factory default is applicable for cables with 5-8.5 mm diameter. In the

cable gland kit, another seals is provided for use with the cables with 7-10 mm diameter.

The instructions for this section are applicable to the AP-228 only.
