Introduction

This document describes how to convert a Lightweight Access Point (LWAP) 1852 to Mobility Express (ME).

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

• CLI access to AP with a console cable.
• Trivial File Transfer Protocol (TFTP) server.

Components Used

The information in this document is based on:

• 1852I AP

Step 1. Download the Mobility express software AIR-AP1850-K9-ME-8-10-112-0.zip and unzip the file.

Step 2. Make sure the 1852 has an Internet Protocol (IP) address.

CLI:

#sh ip int br
gateway-ip  : 10.10.1.254
gateway-mac : 10:05:CA:88:DB:91

Interface  IP-Address      Method   Status                 Protocol  
wired0     10.10.1.230     DHCP     up                     up        
wired1     unassigned      unset    administatively down   down      
wifi0      unassigned      unset    administatively down   down      
wifi1      unassigned      unset    administatively down   down

Step 3. Before the conversion the AP does not mention anything about mobility expressway.
