3 Familiarization and Installation
This chapter describes the adapter and gives instructions on inserting it for the first time.
3.1 The Parts of the Adapter
The adapter has a thin, rectangular end with 68 connector holes, and a thick, rounded end that
contains the antenna and two light-emitting diode (LED) indicators.
The connector end will fit only in a Type II or Type III CardBus slot (also called a "PCMCIA" or
"PC Card" slot) that provides the correct voltage level for the adapter.
The antenna housing will extend outside the slot when the adapter is fully inserted. The LEDs
indicate power and wireless network activity. When the antenna housing faces right like a capital
letter D, the power LED is above the activity LED. The LEDs work as follows:
•
The power LED shines green when the adapter is receiving power from the computer.
Note that power to the adapter can be turned off and on through software.
•
The activity LED shines orange when the adapter is transmitting or receiving.
3.2 Adapter Installation

cautions should, however, be noted:
•
If the adapter is inserted or removed while the computer is running, the operating system
may beep very loudly even if the sound control has been set to
•
If the adapter will be connected to an extender card installed in a desktop computer, make
sure the extender card is firmly bolted to the computer's housing before inserting or
removing the adapter. Shifting or rocking of a loose extender card can result in
