1 About this Guide

This guide provides instructions on how to install and configure your Cisco Aironet 1850 Series Access Point. This guide also provides mounting instructions and limited troubleshooting procedures.

The 1850 Series Access Point is referred to as the access point, or abbreviated as AP in this document.

2 About the Access Point

The Cisco Aironet 1850 series access point is an 802.11 a/b/g/n/ac (Wave 2) access point, with both external antenna (AP1852E) and internal antenna (AP1852I) models. This access point can be mounted on a wall or a ceiling, and supports 2.4 GHz 3x4 802.11b/g/n MIMO and 5 GHz 4x4 802.11 a/n/ac (Wave 2) MIMO applications simultaneously.

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 15 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 11 (optional)

Step 2 Mounting and Grounding the Access Point, page 15

Step 3 Powering the Access Point, page 16

Step 4 Configuring and Deploying the Access Point, page 18

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 20 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 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 26 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 Powering the Access Point, page 16.

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.

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.)

9 Mounting and Grounding the Access Point

Cisco Aironet 1852 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.
