Aruba 324 Installation Manual

Aruba 320 Series Wireless Access Point

Installation Guide

The Aruba 320 Series Wireless Access Points support IEEE 802.11ac standards
for high-performance WLAN, and is equipped with two dual-band radios, which
can provide access and monitor the network simultaneously. Multi-user
Multiple-in, Multiple-output (MU-MIMO) technology allows this access point to
deliver high-performance 802.11n 2.4 GHz and 802.11ac 5 GHz functionality,
while also supporting 802.11a/b/g wireless services.
The AP-324 and AP-325 access points work in conjunction with an Aruba
controller, while the IAP-324 and IAP-325 access points can be configured using
a built-in virtual controller.
The 320 Series Wireless Access Points provide the following capabilities:
 Dual wireless transceiver
IEEE 802.11a/b/g/n/ac operation as a wireless access point

 IEEE 802.11a/b/g/n/ac operation as a wireless air monitor
Compatibility with IEEE 802.3at and 802.3af PoE

 Centralized management configuration and upgrades
 Integrated Bluetooth Low Energy (BLE) radio
This device must be professionally installed and serviced by a trained
ACMP or similar Aruba-certified technician. Aruba access points are
classified as radio transmission devices, and are subject to government
!
regulations of the host country. The network administrator(s) is/are
responsible for ensuring that configuration and operation of this equipment
is in compliance with their country's regulations. For complete list of
approved channels in your country, refer to the Aruba Downloadable
Regulatory Table at www.arubanetworks.com.

Software
The AP-324 and AP-325 require ArubaOS 6.4.4 or higher. For additional
information, refer to the ArubaOS User Guide and ArubaOS Quick Start Guide.
The IAP-324 and IAP-325 require Aruba Instant 4.2.1 or higher. For additional
information, please refer to the Aruba Instant User Guide or the Aruba Instant
Quick Start Guide.
Access points are radio transmission devices and 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.

All Aruba devices with external antennas must be installed by an Aruba
Certified Mobility Professional (ACMP) qualified technician using
manufacturer-approved antennas only. The ACMP installer is responsible
!
for ensuring that the Equivalent Isotropically Radiated Power (EIRP) levels
for all external antenna devices are compliant with regulatory standards of
the host country/domain. Installers are required to record the antenna gain
for this device in the system management software.
USB Interface
The 320 Series is equipped with a USB port for connectivity with cellular
modems and other USB client devices. When powered by an 802.3at or DC
source the USB port can supply up to 5W.
The USB is disabled when powered by an 802.3af PoE.source.

Ethernet Ports

The 320 Series is equipped with two 10/100/1000 Base-T (RJ-45) auto-sensing,
MDI/MDX wired-network connectivity port. These ports support IEEE 802.3af
and 802.3at Power over Ethernet (PoE) compliant sources, accepting 56V DC
(nominal) as a standard defined Powered Device (PD) from a Power Sourcing
Equipment (PSE), such as a PoE midspan injector, or network infrastructure
that supports PoE.
The 10/100/1000 Mbps Ethernet ports are on the bottom of the access point.
These ports have RJ-45 female connectors with the pin-outs shown in

Reset Button

The reset button can be used to return the access point to factory default
settings. To reset the access point, refer to the steps below:
1. Power off the access point.
2. Press and hold the reset button using a small, narrow object, such as a
paperclip.
3. Power-on the access point without releasing the reset button. The power LED
will flash within 5 seconds.
4. Release the reset button.
The power LED will flash again within 15 seconds indicating that the reset is
completed. The access point will now continue to boot with the factory default
settings.

Power

The E0 and E1 port support PoE-in, allowing one port to draw power from an
802.3at (recommended) or an 802.3af source. When both PoE and DC power
sources are available, the access point will default to using the DC power source.
If PoE is not available, the 320 Series has a single 12V/30W DC power jack socket
to support the AP-AC-12V30UN AC-to-DC adapter kit (sold separately).

Power Modes

The 320 Series can operate in two power modes. The modes are not configurable
and are determined by the access point based on the amount of power available.
The 320 Series Wireless Access Points operate without restrictions when
powered by a DC or 802.3at PoE source. When powered by an 802.3af PoE
source, the following restrictions apply:
Second Ethernet port disabled

 USB interface disabled
 2.4 GHz in 1x1:1 mode
