The Aruba AP Deployment Process
Deploying an Aruba AP typically consists of four stages:
1. Run Aruba’s automated RF Plan site-survey software (available separately) to
determine how many Aruba APs are needed and where they will be installed.
2. Ensure that the APs can locate the Mobility Controller when they are installed
and connected to the network.
This is covered in Chapter 2, “AP Installation”.
3. Install the APs by connecting the AP to an Ethernet port and, optionally, to a
power source.
This is covered in Chapter 2, “AP Installation”.
4. On the Mobility Controller, provision the APs.
For AP configuration information, refer to the ArubaOS User Guide.

Aruba AP 70 7

AP Installation 2
This chapter explains how to enable APs to connect to an Aruba Mobility
Controller, and how to install and connect the Aruba AP 70.
Enabling APs to Connect to the Mobility
Controller
Before you install APs in a network environment, you must ensure that the APs
will be able to locate and connect to the Mobility Controller when powered on.
Specifically, you need to ensure the following:
When connected to the network, each AP is assigned a valid IP address
APs are able to locate the Mobility Controller
NOTE:Aruba APs use Trivial File Transfer Protocol (TFTP) the first time they
boot to obtain their software image and configuration from the Mobility
Controller. After the initial boot, the APs use FTP to obtain software
images and configurations from the Mobility Controller.
Enable APs to Obtain IP Addresses
Each Aruba AP requires a unique IP address on a subnetwork that has
connectivity to a Mobility Controller. Aruba recommends using the Dynamic Host
Configuration Protocol (DHCP) to provide IP addresses for APs; the DHCP server
can be an existing network server or an Aruba Mobility Controller configured as a
DHCP server.
You can use an existing DHCP server in the same subnetwork as the AP to
provide the AP with its IP information. You can also configure a device in the
same subnetwork to act as a relay agent for a DHCP server on a different
subnetwork. Refer to the vendor documentation for the DHCP Server or relay
agent for information.
If an AP is on the same subnetwork as the master Mobility Controller, you can
configure the Mobility Controller as a DHCP server to assign an IP address to the
AP. The Mobility Controller must be the only DHCP server for this subnetwork.
See the ArubaOS User Guide for information on how to enable DHCP server
capability on a Mobility Controller:

AP Installation
Chapter 2
8Aruba AP 70 0510159-02
Installation Guide September 2006
Locate the Mobility Controller
An Aruba AP can discover the IP address of the Mobility Controller in one of the
following ways:
From a DNS server
From a DHCP server
Using the Aruba Discovery Protocol (ADP)
From a DNS Server
Aruba APs are factory-configured to use the host name aruba-master for the
Mobility Controller. For the DNS server to resolve this host name to the IP address
of the Mobility Controller, you must configure an entry on the DNS server for the
name aruba-master.
For information on how to configure a host name entry on the DNS server, refer
to the vendor documentation for your server.
NOTE:Aruba recommends using a DNS server to provide APs with the IP
address of the master Mobility Controller because it involves minimal
changes to the network and provides the greatest flexibility in the
placement of APs.
From a DHCP Server
You can configure a DHCP server to provide the Mobility Controller’s IP address.
You need to configure the DHCP server to send the Mobility Controller’s IP
address using the DHCP vendor-specific attribute option 43. Aruba APs identify
themselves with a vendor class identifier set to ArubaAP in their DHCP request.
When the DHCP server responds to the request, it will send the controller’s IP
address as the value of option 43.
For more information on how to configure vendor-specific information on a DHCP
server, see the ArubaOS User Guide or refer to the vendor documentation for your
server.
Using the Aruba Discovery Protocol (ADP)
ADP is enabled by default on all Aruba APs and Mobility Controllers. To use ADP,
all Aruba APs and Mobility Controllers must be connected to the same Layer-2
network. If the devices are on different networks, a Layer-3 compatible discovery
mechanism, such as DNS, DHCP, or IGMP forwarding, must be used instead.
With ADP, APs send out periodic multicast and broadcast queries to locate the
Mobility Controller. You may need to perform additional network configuration,
depending on whether the APs are in the same broadcast domain as the Mobility
Controller:
If the APs are in the same broadcast domain as the Mobility Controller, the
controller automatically responds to the APs’ queries with its IP address.

Aruba AP 70 9
Installation Guide
AP Installation
Chapter 2
If the APs are not in the same broadcast domain as the Mobility Controller,
you need to enable multicast on the network (ADP multicast queries are sent
to the IP multicast group address 224.0.82.11) for the controller to respond
to the APs’ queries. You also need to make sure that all routers are
configured to listen for Internet Group Management Protocol (IGMP) join
requests from the Mobility Controller and can route these multicast packets.
See the ArubaOS User Guide for more information about enabling ADP on the
Mobility Controller.
Mounting the Aruba AP 70
Mount the Aruba AP 70 at its intended service location.
The Aruba AP 70 Access Points are intended only for installation in Environment
A as defined in IEEE 802.3.af. All interconnected equipment must be contained
within the same building, including the interconnected equipment's associated
LAN connections.
Select a location as close as possible to the center of the intended coverage area.
If necessary, use the Aruba RF Plan site survey tool to determine the optimum
locations for your access points and air monitors.
The service location should be free from obstructions or obvious sources of
interference. Normally, the higher you place an access point or air monitor, the
better its performance.
