CAUTION
All Aruba devices with external antennas must be installed by an ACMP qualified technician using
manufacturer-approved antennas only. The ACMP installer(s) is/are responsible for ensuring that Equivalent
Isotropically Radiated Power (EIRP) levels for all external antenna devices are compliant with the regulatory
standards of the host country/domain. Installer(s) are required to record the antenna gain for this device in
system management software.

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
IAP-228 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.

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.
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).
6IAP-228 Wireless Access Point | Installation Guide
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 IAP-228 access point can be installed on a wall by using AP-220-MNT-W1 mount kit.
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.

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.
10 IAP-228 Wireless Access Point | Installation Guide
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 Aruba Instant Quick Start Guide for further details
on verifying post-installation network connectivity.
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.
