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: below a suspended ceiling, on a flat horizontal surface, or on a desktop.
8 Performing a Pre-Installation Configuration For a Cisco Mobility Express deployment, see the Cisco Mobility Express User Guide at this URL: http://www.cisco.com/c/en/us/td/docs/wireless/access_point/mob_exp/1/user_guide/b_ME_User_Guid e.html 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.
Figure 5 Pre-Installation Configuration Setup Controller Layer 3 devices Link Aggregation Cisco Aironet access points 354066 Link Aggregation 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 WCS procedures as described in the appropriate Cisco wireless LAN controller guide. a.
documentation. See also the “Configuring DHCP Option 43” section on page 29 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. See Powering the Access Point, page 19. a.
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.
9 Mounting and Grounding the Access Point Cisco Aironet 3800 series access points can be mounted in several configurations – on a suspended ceiling, on a hard ceiling or wall, on an electrical or network box, and above a suspended ceiling. Go to the following URL for access point mounting instructions: http://www.cisco.com/c/en/us/td/docs/wireless/access_point/mounting/guide/apmount.html The standard mounting hardware supported by the AP is listed in Table 1.
10 Powering the Access Point The AP can be powered using: • 48 V DC power via the 48VDC port, using Cisco Power Adapter AC DC AIR-PWR-C=. Ensure that the power cable is routed through the strain relief retention clips cast into the enclosure. See Figure 6. • Power-over-Ethernet (PoE) from the Ethernet cable, from an external power source such as the Cisco Power Injector AIR-PWRINJ4=.You can also use the AIR-PWRINJ5 Cisco Power Injector but with reduced functionality. • Any 802.3at (25.5 W) or 802.3af (15.

11 Configuring and Deploying the Access Point This section describes how to connect the access point to a wireless LAN controller. Because the configuration process takes place on the controller, see the Cisco Wireless LAN Controller Configuration Guide for additional information. For a Cisco Mobility Express deployment, see the Cisco Mobility Express User Guide at this URL: http://www.cisco.com/c/en/us/td/docs/wireless/access_point/mob_exp/1/user_guide/b_ME_User_Guid e.
Note CAPWAP support is provided in controller software release 5.2 or later. However, your controller must be running the release that supports 3800 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. Note Make sure that the controller is set to the current time.
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 LEDs” section on page 24). a. When you power up the access point, it begins a power-up sequence that you can verify by observing the access point LED.
12 Checking the Access Point LEDs Access Point Status LEDs The location of the access point status LED is shown in Figure 2. Note Regarding LED status colors, it is expected that there will be small variations in color intensity and hue from unit to unit. This is within the normal range of the LED manufacturer’s specifications and is not a defect. The access point status LED indicates various conditions and are described in Table 2.
Ethernet Port LEDs Each Ethernet port has two LEDs for showing Link (Green) and Activity (Amber) statuses. They are integrated on the RJ45 connector. For a description of the statuses they indicate, see the following table.
13 Miscellaneous Usage and Configuration Guidelines Using the Mode Button Using the Mode button (see Figure 3) you can: • Reset the AP to it’s default factory-shipped configuration. • Clear the AP’s internal storage, including all configuration files. To use the mode button, press, and keep pressed, the mode button on the access point during the AP's boot cycle. Wait until the AP's status LED changes to Amber.
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.
• 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.
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.
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 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.
