1 About this Guide
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:
3
–
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
13
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.
