This guide provides mounting instructions and limited troubleshooting procedures. The 3800P series access point is referred to as access point or AP in this document. 2 About the Access Point The Cisco Aironet 3800P series Wi-Fi access point provides 802.11ac Wave 2 with Multi User MIMO (MU MIMO). This AP offers dual-band radios (2.4 GHz and 5 GHz) with external antenna options. The series supports high-performing Spectrum Intelligence which sustains three spatial stream rates over a deployable distance with high reliability when serving clients. The access point supports full inter-interoperability with leading 802.11ac clients, and support a mixed deployment with other access points and controllers. A full listing of the access point's features and specification are provided in the Cisco Aironet 3800 Series Access Point Data Sheet, at the following URL: (URL will be added when available, before FCS) Access Point Features The 3800 series access point is a Dual-band, controller-based 802.11a/g/n/ac AP and supports: • Simultaneous dual-band (2.4-GHz and 5-GHz) radios. • Deployment in indoor environments, with external antennas (AIR-AP3802P-x-K9). The ‘x’ in the model numbers represents the regulatory domain. You need to verify whether the AP model you have is approved for use in your country. To verify approval and to identify the regulatory domain that corresponds to a particular country, visit http://www.cisco.com/go/aironet/compliance. Not all regulatory domains have been approved. As and when they are approved, this compliance list will be updated. • Multi-Gigabit Ethernet (mGig) Support, providing multiple gigabit uplink speeds of 2.5G and 5G in addition to 100M and 1G speeds. • Radio Role Flexibility, allowing for either manual configuration or for the APs to intelligently determine the operating role of the integrated radios based on the available RF environment. The AP can operate in the following modes: – 2.4GHz and 5GHz role, where one radio serves clients in 2.4GHz mode, while the other serves clients in 5GHz mode. – Dual 5GHz role, with both radios operating in the 5GHz band, actively serving client devices to maximize the benefits of 802.11ac wave 2 and to increase client device capacity. – Wireless Security Monitoring and 5GHz role, where one radio serves 5GHz clients, while the other radio scans both 2.4GHz and 5GHz for wIPS attackers, CleanAir interferers, and rogue devices. • Cross-AP Noise Reduction, a Cisco innovation that enables APs to intelligently collaborate in real time about RF conditions so that users connect with optimized signal quality and performance. • Optimized AP Roaming for ensuring that client devices associate with the AP in their coverage range that offers the fastest data rate available. • Cisco ClientLink 4.0 technology for improved downlink performance to all mobile devices, including one-, two-, and three-spatial-stream devices up to 802.11ac Wave 1 and Wave 2. The technology also improves battery life on mobile devices. • Cisco CleanAir technology enhanced with 160MHz channel support. CleanAir delivers proactive, high-speed spectrum intelligence across 20-, 40-, and 80-, and 160-MHz-wide channels to combat performance problems arising from wireless interference. • MIMO equalization capabilities, which optimize uplink performance and reliability by reducing the impact of signal fade. Antennas and Radios The 3800 series access point contains two simultaneous dual-band radios, the 2.4GHz and 5GHz MU-MIMO radio, and the 5-GHz 802.11ac MU-MIMO radio. The 3800P series access point (AIR-AP3802P-x-K9) has two 2.4-GHz/5-GHz dual-band radios, up to 4 external dual-band dipole antennas. The radio and antennas support frequency bands 2400–2500 MHz and 5180–5865 MHz through a common dual-band RF interface. Features of the external dual-band dipole antennas are: • Four RTNC antenna connectors on the top of the access point • Four TX/RX antennas Supported External Antennas Frequency Part Number 2.4GHz AIR-ANT24020V-R 5GHz 2.4GHz and 5GHz Antenna Type AIR-ANT2452V-R Diversity Omni-directional AIR-ANT2430V-R MIMO 3-Element Omni AIR-ANT2440NV-R MIMO Wall-Mount Omni Antenna AIR-ANT2460NP-R MIMO 3-Element Patch AIR-ANT5140V-R MIMO 3-Element Omni AIR-ANT5140NV-R MIMO Wall-Mount Omni Antenna AIR-ANT5145V-R Diversity Omni-directional AIR-ANT5160NP-R MIMO 3-Element Patch AIR-ANT2451V-R AIR-ANT2451NV-R AIR-ANT2524DB-R Dual-resonant black dipole AIR-ANT2524DW-R Dual-resonant white dipole AIR-ANT2524DG-R Dual-resonant gray dipole AIR-ANT2524V4C-R Dual-resonant ceiling mount omni (4-pack) AIR-ANT2535SDW-R Dual-resonant "stubby" monopole AIR-ANT2544V4M-R Dual-resonant omni (4-pack) AIR-ANT2566P4W-R Dual-resonant "directional" antenna (4-pack) AIR-ANT2566D4M-R Dual-Band Polarization-Diverse Directional Array AIR-ANT2513P4M-N Dual-resonant cross-pol "directional" antenna (4-pack) For additional details on the supported antennas, such as antenna gain, and information such as channels and maximum power settings, see the Channels and Maximum Power Settings for Cisco 3800 Series Access Points sheet at the following URL: (To be added when available, before FCS) 3 Safety Instructions Translated versions of the following safety warnings are provided in the translated safety warnings document that is shipped with your access point.

Figure 3 10 AP Module Connector Port on the Base 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. Note You can mount the access point above a suspended ceiling but you must purchase additional mounting hardware: See “Mounting and Grounding the Access Point” section on page 16 for additional information. • Access point power options: power supplied by the recommended external power supply (Cisco AIR-PWR-C), a DC power supply, PoE from a network device, or a PoE power injector/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 12 (optional) Step 2 Mounting and Grounding the Access Point, page 16 Step 3 Powering the Access Point, page 17 Step 4 Preparing the AP for Installation, page 11 11 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. 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 21 for details. The following Pre-Installation Configuration procedure given does not include configuring Link Aggregation. For information on configuring Link Aggregation, see the Cisco Wireless LAN Controller Configuration Guide, Release 8.1, at this URL: http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/configuration-guide/b_cg81.html The pre-installation configuration setup is illustrated in Figure 4. 12 Figure 4 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. 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 13 documentation. See also the “Configuring DHCP Option 43” section on page 27 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 17. a. As the access point attempts to connect to the controller, the LEDs cycle 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. 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. 14 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.) 15 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. Table 1 Brackets and Clips for Mounting the AP Part Number Brackets AIR-AP-BRACKET-1 Description Low-profile bracket (This is the default option) Clips AIR-AP-BRACKET-2 Universal bracket AIR-AP-T-RAIL-R Ceiling Grid Clip (Recessed mounting) (This is the default option) 16 AIR-AP-T-RAIL-F Ceiling Grid Clip (Flush mounting) AIR-CHNL-ADAPTER Optional adapter for channel-rail ceiling grid profile. 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 5. • 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 (15.4 W) compliant power injector. However, when powered by an 802.3af powering source, the AUX and USB ports are disabled. The 2.4GHz radio will shift to 2x3:2SS operation and the 5GHz radio will remain at full operation. With an 802.3at or the AIR-PWR-C= as the power source, the AP provides full operation including the AUX and USB ports. 17 Figure 5 Routing the DC Power Cable 353859 Kensington lock slot DC power cable plugged into the 48VDC port Power cable routed through the strain relief retention clips AP secured using a padlock DC power cable 18 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.html The information in this section does not include configuring Link Aggregation. For information on configuring Link Aggregation, see the Cisco Wireless LAN Controller Configuration Guide, Release 8.1, at the following URL: http://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/configuration-guide/b_cg81.html 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. 19 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. If the controller is set to a time that has already occurred, 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 12. • 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 27. • 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. 20 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 22). 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 27 for additional information. Step 3 Reconfigure the Cisco wireless LAN controller so that it is not the Master. Note A Master Cisco wireless LAN controller should be used only for configuring access points and not in a working network. 21 12 Checking the Access Point LEDs Access Point Status LEDs The location of the access point status LED is shown in Figure 1. 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. Table 2 LED Status Indications Message Type LED State Message Meaning Association status Chirping Green Normal operating condition, but no wireless client associated Green Normal operating condition, at least one wireless client association Boot loader status Green Executing boot loader Boot loader error Red Boot loader signing verification failure Operating status Blinking amber Software upgrade in progress Cycling through green, red, and amber Discovery/join process in progress Rapidly cycling through red, green, amber, and off. Access point location command invoked from controller web interface. Cycling through red, green, amber, and off General warning; insufficient inline power Access point operating system errors 22 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. 10M Link 10M Active 100M Link 100M Active 1000M 1000M Link Active Link (Green) LED State Off Off Off Off On Activity (Amber) LED State On Blinking On Blinking On On Blinking 23 13 Miscellaneous Usage and Configuration Guidelines Using the Mode Button Using the Mode button (see Figure 2) 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. During this, the AP console shows a seconds counter, counting the number of seconds the mode button is pressed. Then: • To reset the AP to it’s default factory-shipped configuration, keep the mode button pressed for less than 20 seconds. The AP's configuration files are cleared. This resets all configuration settings to factory defaults, including passwords, WEP keys, the IP address, and the SSID. • To clear the AP’s internal storage, including all configuration files and the regulatory domain configuration, keep the mode button pressed for more than 20 seconds, but less than 60 seconds. The AP's status LED changes from Amber to Red, and all the files in the AP's storage directory are cleared. If you keep the mode button pressed for more than 60 seconds, the mode button is assumed faulty and no changes are made. 24 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. 25 • 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 3802 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. 26 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. Note DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a separate DHCP pool for each access point type. The 3800 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 3800 series access point is: Cisco AP c3800 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 poolnetwork default-router dns-server Where: is the name of the DHCP pool, such as AP3802 is the network IP address where the controller resides, such as 10.0.15.1 27 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. 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, 10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is option 43 hex f1080a7e7e020a7f7f02. 14 Related Documentation All user documentation for the Cisco Aironet 3800 series access point is available at the following URL: (URL to be added at FCS) For detailed information and guidelines for configuring and deploying your access point in a wireless network, see the following documentation: • Cisco Wireless LAN Controller Configuration Guide, Release 8.3, at the following URL: (URL to be added at FCS) • Cisco Aironet 3800 Series Access Point Deployment Guide, at the following URL: (URL to be added when available) 28 15 Declarations of Conformity and Regulatory Information This section provides declarations of conformity and regulatory information for the Cisco Aironet 3800 Series Access Points.
