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.
Access Point Model Numbers and Regulatory Domains
The Cisco Aironet 1850 series access point comes in both universal regulatory domain and
non-universal regulatory domain model number formats. See the following table for the model number
formats.
The ‘UX’ in a model number indicates a universal regulatory domain access point. For information on
how to set the regulatory domain and country configurations of a universal regulatory domain access
point, see the Cisco Aironet Universal AP Priming and Cisco AirProvision User Guide, at:
http://www.cisco.com/c/en/us/td/docs/wireless/access_point/ux-ap/guide/uxap-mobapp-g.html

Translated versions of the following safety warnings are provided in the translated safety warnings
document that is shipped with your access point. The translated warnings are also in the Translated
Safety Warnings for Cisco Aironet Access Points, which is available on Cisco.com.
Warning IMPORTANT SAFETY INSTRUCTIONS
This warning symbol means danger. You are in a situation that could cause bodily injury.
Before you work on any equipment, be aware of the hazards involved with electrical
circuitry and be familiar with standard practices for preventing accidents. Use the

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.
