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

320 Series Hardware Overview
Figure 1 LEDs
LEDs
The 320 Series access points have two LEDs that indicate the system and radio
status of the device.
.
External Antenna Connectors
The (I)AP-324 access points are equipped with four external antenna connectors
located on the front corners of the access point (see Figure 2).

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.
Figure 3 Bottom Panel
Console Port
The serial console port allows the user to connect the access point to a serial
terminal or a laptop for direct local management. This port is an RJ-45
connector, with pinouts details in Figure 4. Connect it directly to a terminal or
terminal server using an Ethernet cable.
Figure 4 Serial Port Pin-Out
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 Figure
5.

Kensington Lock Slot
The 320 Series is equipped with a Kensington lock slot for additional security.
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
Before You Begin
Access Point Pre-Installation Checklist
Before installing your 320 Series access point, ensure that you have the
following:
 CAT5E or CAT6 UTP cable of required length
 One of the following power sources:
 IEEE 802.3at or 802.3af-compliant Power over Ethernet (PoE) source. The
PoE source can be any power source equipment (PSE) controller or
midspan PSE device
 Aruba APAC-DC adapter kit (sold separately)
For AP-324 and AP-325 only:
 Aruba Controller provisioned on the network:
 Layer 2/3 network connectivity to your access point
 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 installing access points in a network environment, make sure that they
are able to locate and connect to the controller after power on.
Specifically, you must verify the following conditions:
 When connected to the network, each access point is assigned a valid IP
address
 Access points are able to locate the controller

CAUTION
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.
Inform your supplier if there are any incorrect, missing, or damaged parts. If
possible, retain the carton, including the original packing materials. Use
these materials to repack and return the unit to the supplier if needed.
