This guide provides instructions on how to install your Cisco Aironet 3800P series access point and provides links to resources which can help you configure the access point. 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.

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

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).

“Mounting and Grounding the Access Point” section

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.

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

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

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 y

our 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 wir

eless 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. CAPW

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 27 for more information.

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 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.
