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: vertically oriented, on a wall or a desk.
• Powered by 802.3af or 802.3at, 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.
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)
Step 2
Mounting and Powering the Access Point, page 13
Step 3
Configuring and Deploying the Access Point, page 16
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 “Deploying the Access Point on the Wireless
Network” section on page 18 for details.
The pre-installation configuration setup is illustrated in Figure 3.

To perform pre-installation configuration, perform the following steps:
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 “Configuring DHCP Option 43” section on page 24 for more
information.
Note
Step 2
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.
Apply power to the access point.
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.
11
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.
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
12
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.)
9 Mounting and Powering the Access Point
The Cisco Aironet 1800i series access points can be mounted, in a vertical orientation, on a wall or
desk, to a height of 3 feet. The mounting is done using the wall-mount bracket AIR-AP-BRACKET-NS.
To mount the AP on a wall or desk:
Step 1
Identify the location for mounting the AP.
Step 2
Use the wall-mount bracket AIR-AP-BRACKET-NS, as a template to mark the two screw-hole
locations for fastening the bracket to the wall or desk.
Step 3
At the marked locations, drill a hole into the wall or desk.
Step 4
Fasten the AIR-AP-BRACKET-NS to the wall using two 18mm screws.
Step 5
Hold the back of the AP against the wall, above the bracket, and then slide the AP down onto
the bracket, till it clicks into place. The hooks on the bracket will click into the recesses on
the back of the AP.
Step 6
Proceed with connecting the data and power cables.
The AP can be powered using:
• AC power, using the AC-USB adapter AIR-MOD-USB, supplying 5V DC, 1.5A power.
• PoE, 802.3af Class 0 power or greater, from:
– a network device or power injector.
– Cisco power injectors AIR-PWRINJ5 (for 802.3af) or AIR-PWRINJ6 (for 802.3at).
The PoE and USB ports are located on the base of the AP. When both AC power and PoE power is
available, the PoE power takes precedence.

10 Configuring and Deploying the Access Point
This section describes how to connect the access point to a wireless LAN controller. The configuration
process takes place on the controller. See the Cisco Wireless LAN Controller Configuration Guide for
additional information.
The Controller Discovery Process
The access point uses standard Control and Provisioning of Wireless Access Points Protocol
(CAPWAP) to communicate between the controller and other wireless access points on the network.
CAPWAP is a standard, inter-operable protocol which enables an access controller to manage a
collection of wireless termination points. The discovery process using CAPWAP is identical to the
Lightweight Access Point Protocol (LWAPP) used with previous Cisco Aironet access points.
LWAPP-enabled access points are compatible with CAPWAP, and conversion to a CAPWAP controller
is seamless. Deployments can combine CAPWAP and LWAPP software on the controllers.
The functionality provided by the controller does not change except for customers who have Layer 2
deployments, which CAPWAP does not support.
In a CAPWAP environment, a wireless access point discovers a controller by using CAPWAP discovery
mechanisms and then sends it a CAPWAP join request. The controller sends the access point a
CAPWAP join response allowing the access point to join the controller. When the access point joins
the controller, the controller manages its configuration, firmware, control transactions, and data
transactions.
Note
For additional information about the discovery process and CAPWAP, see the Cisco Wireless
LAN Controller Software Configuration Guide. This document is available on Cisco.com.
Note
CAPWAP support is provided in controller software release 5.2 or later. However, your
controller must be running the release that supports 1800i series access points, as specified in
the access point’s data sheet.
Note
You cannot edit or query any access point using the controller CLI if the name of the access
point contains a space.
16
Note
Make sure that the controller is set to the current time. If the controller is set to a time that
has already passed, the access point might not join the controller because its certificate may
not be valid for that time.
Access points must be discovered by a controller before they can become an active part of the network.
The access point supports these controller discovery processes:
• Layer 3 CAPWAP discovery—Can occur on different subnets than the access point and uses IP
addresses and UDP packets rather than MAC addresses used by Layer 2 discovery.
• Locally stored controller IP address discovery—If the access point was previously joined to a
controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the
access point’s non-volatile memory. This process of storing controller IP addresses on an access
point for later deployment is called priming the access point. For more information about priming,
see the “Performing a Pre-Installation Configuration” section on page 10.
• DHCP server discovery—This feature uses DHCP option 43 to provide controller IP addresses to
the access points. Cisco switches support a DHCP server option that is typically used for this
capability. For more information about DHCP option 43, see the “Configuring DHCP Option 43”
section on page 24.
• DNS discovery—The access point can discover controllers through your domain name server
(DNS). For the access point to do so, you must configure your DNS to return controller IP
addresses in response to CISCO-CAPWAP-CONTROLLER.localdomain, where localdomain is
the access point domain name. Configuring the CISCO-CAPWAP-CONTROLLER provides
backwards compatibility in an existing customer deployment. When an access point receives an IP
address and DNS information from a DHCP server, it contacts the DNS to resolve
CISCO-CAPWAP-CONTROLLER.localdomain. When the DNS sends a list of controller IP
addresses, the access point sends discovery requests to the controllers.
17
Deploying the Access Point on the Wireless Network
After you have mounted the access point, follow these steps to deploy it on the wireless network:
Step 1
Connect and power up the access point.
Step 2
Observe the access point LED (for LED descriptions, see “Checking the Access Point LED”
section on page 19).
a. When you power up the access point, it begins a power-up sequence that you can verify by
observing the access point LED. If the power-up sequence is successful, the discovery and join
process begins. During this process, the LED blinks sequentially green, red, and off. When the
access point has joined a controller, the LED is chirping green if no clients are associated or
green if one or more clients are associated.
b. If the LED is not on, the access point is most likely not receiving power.
c. If the LED blinks sequentially for more than 5 minutes, the access point is unable to find its
primary, secondary, and tertiary Cisco wireless LAN controller. Check the connection
between the access point and the Cisco wireless LAN controller, and be sure the access point
and the Cisco wireless LAN controller are either on the same subnet or that the access point
has a route back to its primary, secondary, and tertiary Cisco wireless LAN controller. Also,
if the access point is not on the same subnet as the Cisco wireless LAN controller, be sure that
there is a properly configured DHCP server on the same subnet as the access point. See the
“Configuring DHCP Option 43” section on page 24 for additional information.
Step 3
Reconfigure the Cisco wireless LAN controller so that it is not the Master.
Note
18
A Master Cisco wireless LAN controller should be used only for configuring access
points and not in a working network.
11 Checking the Access Point LED

12 Miscellaneous Usage and Configuration Guidelines
Using the Reset Button
Using the Reset button you can:
• Reset the AP to the default factory-shipped configuration.
• Clear the AP internal storage, including all configuration files and the regulatory domain
configuration.
To use the Reset button, press, and keep pressed, the Reset button on the access point during the AP
boot cycle. Wait until the AP status LED changes to Amber. During this, the AP console shows a
seconds counter, counting the number of seconds the Reset button is pressed. Then:
• To reset the AP to the default factory-shipped configuration, keep the Reset button pressed for less
than 20 seconds. The AP configuration files are cleared.
This resets all configuration settings to factory defaults, including passwords, encryption keys, the
IP address, and the SSID. However, the regulatory domain provisioning is not reset.
• To clear the AP internal storage, including all configuration files and the regulatory domain
configuration, keep the Reset button pressed for more than 20 seconds, but less than 60 seconds.
The AP status LED changes from Amber to Red, and all the files in the AP storage directory are
cleared.
If you keep the Reset button pressed for more than 60 seconds, the Reset button is assumed faulty and
no changes are made.
21
Troubleshooting the Access Point to Cisco Controller Join Process
Note
Ensure that your controller is running the latest Cisco Wireless Controller Software Release
as specified in the access point’s data sheet.
Access points can fail to join a controller for many reasons: a RADIUS authorization is pending;
self-signed certificates are not enabled on the controller; the access point’s and controller’s regulatory
domains don’t match, and so on.
Controller software enables you to configure the access points to send all CAPWAP-related errors to
a syslog server. You do not need to enable any debug commands on the controller because all of the
CAPWAP error messages can be viewed from the syslog server itself.
The state of the access point is not maintained on the controller until it receives a CAPWAP join
request from the access point. Therefore, it can be difficult to determine why the CAPWAP discovery
request from a certain access point was rejected. In order to troubleshoot such joining problems
without enabling CAPWAP debug commands on the controller, the controller collects information for
all access points that send a discovery message to it and maintains information for any access points
that have successfully joined it.
The controller collects all join-related information for each access point that sends a CAPWAP
discovery request to the controller. Collection begins with the first discovery message received from
the access point and ends with the last configuration payload sent from the controller to the access
point.
You can view join-related information for up to three times the maximum number of access points
supported by the platform for the 2500 series controllers and the Controller Network Module within
the Cisco 28/37/38xx Series Integrated Services Routers.
Note
The maximum number of access points varies for the Cisco WiSM2, depending on which
controller software release is being used.
When the controller is maintaining join-related information for the maximum number of access points,
it does not collect information for any more access points.
An access point sends all syslog messages to IP address 255.255.255.255 by default when any of the
following conditions are met:
• An access point running software release 8.0.x.x or later has been newly deployed.
22
• An existing access point running software release 8.0.x.x or later has been reset after clearing the
configuration.
If any of these conditions are met and the access point has not yet joined a controller, you can also
configure a DHCP server to return a syslog server IP address to the access point using option 7 on the
server. The access point then starts sending all syslog messages to this IP address.
When the access point joins a controller for the first time, the controller sends the global syslog server
IP address (the default is 255.255.255.255) to the access point. After that, the access point sends all
syslog messages to this IP address until it is overridden by one of the following scenarios:
• The access point is still connected to the same controller, and the global syslog server IP address
configuration on the controller has been changed using the config ap syslog host global
syslog_server_IP_address command. In this case, the controller sends the new global syslog server
IP address to the access point.
• The access point is still connected to the same controller, and a specific syslog server IP address
has been configured for the access point on the controller using the config ap syslog host specific
Cisco_AP syslog_server_IP_address command. In this case, the controller sends the new specific
syslog server IP address to the access point.
• The access point is disconnected from the controller and joins another controller. In this case, the
new controller sends its global syslog server IP address to the access point.
• Whenever a new syslog server IP address overrides the existing syslog server IP address, the old
address is erased from persistent storage, and the new address is stored in its place. The access
point also starts sending all syslog messages to the new IP address provided the access point can
reach the syslog server IP address.
You can configure the syslog server for access points and view the access point join information only
from the controller CLI.
Important Information for Controller-based Deployments
Keep these guidelines in mind when you use 1800i series access points:
• The access point can only communicate with Cisco wireless LAN controllers.
• The access point does not support Wireless Domain Services (WDS) and cannot communicate with
WDS devices. However, the controller provides functionality equivalent to WDS when the access
point joins it.
• CAPWAP does not support Layer 2. The access point must get an IP address and discover the
controller using Layer 3, DHCP, DNS, or IP subnet broadcast.
• The access point console port is enabled for monitoring and debug purposes. All configuration
commands are disabled when the access point is connected to a controller.
23
Configuring DHCP Option 43
You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling
them to find and join a controller.
The following is a DHCP Option 43 configuration example on a Windows 2003 Enterprise DHCP
server for use with Cisco Aironet lightweight access points. For other DHCP server implementations,
consult product documentation for configuring DHCP Option 43. In Option 43, you should use the
IP address of the controller management interface.
The 1800i series access point uses the type-length-value (TLV) format for DHCP Option 43. DHCP
servers must be programmed to return the option based on the access point’s DHCP Vendor Class
Identifier (VCI) string (DHCP Option 43). The VCI string for the 1800i access point is:
Cisco AP c1800i
The format of the TLV block is listed below:
• Type: 0xf1 (decimal 241)
• Length: Number of controller IP addresses * 4
• Value: List of WLC management interfaces
To configure DHCP Option 43 in the embedded Cisco IOS DHCP server, follow these steps:
Step 1
Enter configuration mode at the Cisco IOS CLI.
Step 2
Create the DHCP pool, including the necessary parameters such as default router and name
server. A DHCP scope example is as follows:
ip dhcp pool 
network  
default-router 
dns-server 
Where:
 is the name of the DHCP pool, such as AP1800i
 is the network IP address where the controller resides, such as
10.0.15.1
 is the subnet mask, such as 255.255.255.0
 is the IP address of the default router, such as 10.0.0.1
 is the IP address of the DNS server, such as 10.0.10.2
Step 3
24
Add the option 43 line using the following syntax:
option 43 hex 
The hex string is assembled by concatenating the TLV values shown below:
Type + Length + Value
Type is always f1(hex). Length is the number of controller management IP addresses times 4
in hex. Value is the IP address of the controller listed sequentially in hex.
For example, suppose that there are two controllers with management interface IP addresses,

Santé Canada affirme que la littérature scientifique actuelle n'indique pas qu'il faille prendre des
précautions particulières lors de l'utilisation d'un appareil sans fil. Si vous voulez réduire votre
exposition encore davantage, selon l'agence, vous pouvez facilement le faire en réorientant les antennes
afin qu'elles soient dirigées à l'écart de l'utilisateur, en les plaçant à une distance d'éloignement
supérieure à celle recommandée ou en réduisant la puissance de sortie de l'émetteur.
