AP Installation
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
N
:
Aruba APs use Trivial File Transfer Protocol (TFTP) the first time they
OTE
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:
