Warnings
Observe the following warnings when operating the client adapter:
Warning
Warning
Warning
Do not operate your wireless network device near unshielded blasting caps or in an explosive
environment unless the device has been modified to be especially qualified for such use.
In order to comply with FCC radio frequency (RF) exposure limits, dipole antennas should be located
at a minimum of 7.9 inches (20 cm) or more from the body of all persons.
In order to comply with RF exposure limits established in the ANSI C95.1 standards, it is recommended
when using a laptop with a PC card client adapter that the adapter’s integrated antenna is positioned
more than 2 inches (5 cm) from your body or nearby persons during extended periods of transmitting
or operating time. If the antenna is positioned less than 2 inches (5 cm) from the user, it is
recommended that the user limit exposure time.
Translated versions of these safety warnings are provided in Appendix B.
Unpacking the Client Adapter
Follow these steps to unpack the client adapter:

System Requirements
System Requirements
In addition to the items shipped with the client adapter, you also need the following items in order to
install and use the adapter:
•
One of the following computing devices running Windows 98, 98 SE, NT, 2000, Me, or XP:
–
–
–
–
Laptop or notebook computer equipped with a Type II or Type III PC card slot or Cardbus slot
Desktop personal computer equipped with an empty PCI expansion slot
Handheld or portable device with an embedded LM card
Laptop or other computing device with an embedded mini PCI card
Note
Install Wizard version 1.3 or later and its software components are not supported for use
with Windows 98, 98 SE, NT, and Me.
Note
Note
Note
PC-Cardbus cards are not supported for use with Windows NT.
Cisco recommends using a display with a minimum resolution of 800 x 600 pixels.
All drivers and supporting software (Card and Socket Services) for the PC card slot or
Cardbus slot must be loaded and configured.
•
•
35 MB of free hard disk space (minimum)
A maximum of eight network connections if your computer is running Windows 98 or 98 SE
Note
Windows 98 and 98 SE limit your computer’s network connections. If you try to install a
client adapter when eight network devices (such as a PCMCIA Ethernet card, dial-up
adapter, VPN adapter, docking station Ethernet card, etc.) are already connected to your
computer, the new adapter cannot establish a network connection.
•
•
•
Windows NT Service Pack 6 or later if your computer is running Windows NT
A Phillips screwdriver (for PCI cards)
Software with WPA support if your wireless network uses host-based EAP authentication with
WPA:
–
–
Funk Odyssey Client supplicant version 2.2 (for Windows 2000)
Windows XP Service Pack 1 and Microsoft support patch 815485 (for Windows XP)
Note
Meetinghouse AEGIS Client supplicant version 2.1 or later is also supported for use with
Windows 2000 and XP; however, it was not tested with this client adapter software release.
•
The Microsoft 802.1X supplicant, if your wireless network uses EAP-TLS, PEAP, or EAP-SIM
authentication

Site Requirements
•
•
If your wireless network uses PEAP authentication with a One-Time Password (OTP) user database:
–
SofToken version 1.3, 2.0, or later from Secure Computing; SecurID version 2.5 from RSA; or
hardware token from OTP vendors
–
Your software token PIN or hardware token password
If your wireless network uses EAP-SIM authentication:
–
–
–
PCSC-compliant smartcard reader installed in your computer’s Type II or Type III PC card slot
Gemplus SIM+ smartcard inserted in the reader
The SIM card’s PIN
Note
The EAP-SIM supplicant included in the Install Wizard file supports only Gemplus SIM+
cards; however, an updated supplicant is available that supports standard GSM-SIM cards as
well as more recent versions of the EAP-SIM protocol. The new supplicant is available for
download from Cisco.com at the following URL:
•
The following information from your system administrator:
–
–
–
–
The logical name for your workstation (also referred to as client name)
The protocols necessary to bind to the client adapter
The case-sensitive service set identifier (SSID) for your RF network
If your network setup does not include a DHCP server, the IP address, subnet mask, and default
gateway address of your computer
–
The wired equivalent privacy (WEP) keys of the access points with which your client adapter
will communicate, if your wireless network uses static WEP for security
–
–
The username and password for your network account
Protected access credentials (PAC) file if your wireless network uses EAP-FAST authentication
with manual PAC provisioning
Site Requirements
This section discusses the site requirements for both infrastructure and client devices.
For Infrastructure Devices
Because of differences in component configuration, placement, and physical environment, every
network application is a unique installation. Therefore, before you install any wireless infrastructure
devices (such as access points, bridges, and base stations, which connect your client adapters to a wired
LAN), a site survey must be performed to determine the optimum placement of these devices to
maximize range, coverage, and network performance. Appendix F, which is provided for people who
are responsible for conducting a site survey, explains how ACU’s site survey tool can be used to
determine the best placement for infrastructure devices within a wireless network.
Note
Infrastructure devices are installed and initially configured prior to client devices.

For Client Devices
Because the client adapter is a radio device, it is susceptible to RF obstructions and common sources of
interference that can reduce throughput and range. Follow these guidelines to ensure the best possible
performance:
•
Install the client adapter in an area where large steel structures such as shelving units, bookcases,
and filing cabinets will not obstruct radio signals to and from the client adapter.
•
Install the client adapter away from microwave ovens. Microwave ovens operate on the same
frequency as the client adapter and can cause signal interference.
