6 Preparing the AP for Installation
Before you mount and deploy your access point, we recommend that you perform a site survey (or use
the site planning tool) to determine the best location to install your access point.
You should have the following information about your wireless network available:
• Access point locations.
• Access point mounting options: on a wall or a ceiling only.
Note You can mount the access point above a suspended ceiling but you must purchase
additional mounting hardware: See
on page 13 for additional information.
• Powered by 802.3af, through PoE from a network device or a PoE power injector or hub (usually
located in a wiring closet).
Note Access points mounted in a building’s environmental airspace must be powered using PoE
to comply with safety regulations.
“Mounting and Grounding the Access Point” section
Cisco recommends that you make a site map showing access point locations so that you can record the
device MAC addresses from each location and return them to the person who is planning or managing
your wireless network.
7 Installation Overview
Installing the access point involves these operations:
Step 1 Performing a Pre-Installation Configuration, page 10 (optional)

8 Performing a Pre-Installation Configuration
The following procedures ensure that your access point installation and initial operation go as
expected. This procedure is optional.
Note Performing a pre-installation configuration is an optional procedure. If your network
controller is properly configured, you can install your access point in its final location and
connect it to the network from there. See the
Network” section on page 16 for details.
“Deploying the Access Point on the Wireless
The pre-installation configuration setup is illustrated in

To perform pre-installation configuration, perform the following steps:
10
Step 1 Make sure that the Cisco wireless LAN controller DS port is connected to the network. Use
the CLI, web-browser interface, or Cisco Prime Infrastructure procedures as described in the
appropriate Cisco wireless LAN controller guide.
a. Make sure that access points have Layer 3 connectivity to the Cisco wireless LAN controller
Management and AP-Manager Interface.
b. Configure the switch to which your access point is to attach. See the Cisco Wireless LAN
Controller Configuration Guide for the release you are using, for additional information.
c. Set the Cisco wireless LAN controller as the master so that new access points always join with
it.
d. Make sure DHCP is enabled on the network. The access point must receive its IP address
through DHCP.
e. CAPWAP UDP ports must not be blocked in the network.
f. The access point must be able to find the IP address of the controller. This can be
accomplished using DHCP, DNS, or IP subnet broadcast. This guide describes the DHCP
method to convey the controller IP address. For other methods, refer to the product
documentation. See also the
information.
“Configuring DHCP Option 43” section on page 22 for more
Note The access point requires a Gigabit Ethernet (GbE) link to prevent the Ethernet port from
becoming a bottleneck for traffic because wireless traffic speeds exceed transmit speeds
of a 10/100 Ethernet port.
Step 2 Apply power to the access point. See
a. As the access point attempts to connect to the controller, the LED cycles through a green, red,
and amber sequence, which can take up to 5 minutes.
Note If the access point remains in this mode for more than five minutes, the access point is
unable to find the Master Cisco wireless LAN controller. Check the connection between
the access point and the Cisco wireless LAN controller and be sure that they are on the
same subnet.
b. If the access point shuts down, check the power source.
c. After the access point finds the Cisco wireless LAN controller, it attempts to download the
new operating system code if the access point code version differs from the Cisco wireless
LAN controller code version. While this is happening, the Status LED blinks amber.
“Powering the Access Point” section on page 13.
11
d. If the operating system download is successful, the access point reboots.
Step 3 Configure the access point if required. Use the controller CLI, controller GUI, or Cisco Prime
Infrastructure to customize the access-point-specific 802.11ac network settings.
Step 4 If the pre-installation configuration is successful, the Status LED is green indicating normal
operation. Disconnect the access point and mount it at the location at which you intend to
deploy it on the wireless network.
Step 5 If your access point does not indicate normal operation, turn it off and repeat the
pre-installation configuration.
Note When you are installing a Layer 3 access point on a different subnet than the Cisco
wireless LAN controller, be sure that a DHCP server is reachable from the subnet on
which you will be installing the access point, and that the subnet has a route back to
the Cisco wireless LAN controller. Also be sure that the route back to the Cisco
wireless LAN controller has destination UDP ports 5246 and 5247 open for CAPWAP
communications. Ensure that the route back to the primary, secondary, and tertiary
wireless LAN controller allows IP packet fragments. Finally, be sure that if address
translation is used, that the access point and the Cisco wireless LAN controller have
a static 1-to-1 NAT to an outside address. (Port Address Translation is not
supported.)
