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).

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

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.

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.
