Cisco Cisco Aironet 350 Wireless LAN Client Adapter

This document describes system requirements, important notes, installation and upgrade procedures, and 
caveats for CB21AG and PI21AG client adapter ACAU release 1.1.

ACAU is a utility used by administrators to configure administrative overrides and create profiles for 
users who install CB21AG and PI21AG wireless client adapters in PCs running the Windows 2000 or 
Windows XP operating system. The overrides and profiles are stored in a configuration file that is loaded 
by the Install Wizard. After the user installs the driver and Aironet Desktop Utility (ADU) for the client 
adapter, the Install Wizard uses the instructions in the configuration file to preconfigure ADU user 
settings and load one or more user profiles.

Using ACAU, an administrator can perform the following operations:

Determine and configure the setup options for the ADU software

Set ADU user functions

Create preconfigured user profiles for a user or group of users

Generally, the system requirements for ACAU are the same as for the client adapter:

A computer running the Windows 2000 or XP operating system

Cisco recommends a 300-MHz (or greater) processor.

Service Pack 1 for Windows XP

20 MB of free hard disk space (minimum)

128 MB of RAM or greater (recommended)

If the wireless network uses EAP-TLS or PEAP authentication, the following must be on the user’s 
PC:

Certificate of Authority (CA) and user certificates for EAP-TLS authentication or CA certificate 
for PEAP authentication

If the wireless network uses PEAP (EAP-GTC) authentication with a One-Time Password (OTP) 
user database, the following must be on the user’s PC:

A hardware token device from OTP vendors or Secure Computing SofToken program (release 
2.1 or later)
