Inserting and Removing a Client Adap ter

This section provides in struct ions for in ser ting a nd rem oving PC card s, PC-C ar dbus cards, a nd PCI cards. Instructions ar e not provide d for LM card s and mini PCI cards because they are pre- install ed inside computing devices a nd ar e not me ant to be i nsta ll ed or r emoved by the u ser.

Caution These procedures a nd the physic al c onn ect ions they de scri be a pp ly g en erall y t o

conventional PC card slots, Cardbus slots, and PCI expansion slots. In cases of custom or nonconventional equipment, be ale rt to possi ble difference s in PC c ard sl ot, Car dbus slot, and PCI expansion slot configurations.

Inserting a Client Adapter

Follow the instructions in one of the sections below to insert a PC card, PC-Cardbus card, or PCI card into a computing device.

Chapter8 Routine Procedures

Inserting a PC Card or PC-Cardbus Card

Step 1 Before yo u begin, examine th e card. O ne end has a dua l-row, 68-pin connector. The card is keyed so it

can be inserted only on e way int o t he PC c ard s lot or Card bus slot.

Note The PC card slot o r Cardbus sl ot is on the le ft o r r ight sid e of the com pute r,

depending on th e mod el .

Step 2 Follow the instructions below for your specific operating system:

• Windows 95, Windows 98, Windows 2000, Windows Me, or Windows XP– Turn on your

computer, let th e operating system boot up completely , and follow the remaining steps in this section to insert the card.

• Windows NT – Turn off your comput er , follo w the remain ing steps in this secti on to insert the card ,

and reboot your compu ter.

Caution Do not force the card into your computer’s PC card slot or Cardbus slot. Forcing it will

damage both the card and the slot. If the card does not insert easily, remove the card and reinsert it.

Step 3 Hold the card with the Cisco logo faci ng up and insert it into the PC card slot or Cardbus slot, applying

just enough pressure to make sure it is fully seated (see Figure 8-1).

An ACU icon is automatically added to the desktop when you install ACU, provided you selected this option during installation. If you wish to remove this icon from your desktop, right-click the ico n, clic k Delete, and click Yes to confirm your decision.

Restarting the Client Adapter

ACU enables you to re-initialize (or restart) the client adapter without having to reboot your computer or eject and reinsert the adapter. For instance, if your client adapter is experiencing poor throughput, you might want to restart the client adapte r to try to force it to disassociate from the access point to which it is currently associated in the hope that it will reassociate to an access point with a stronger signal.

Note Restartin g the cli ent a dapt er m a y ca use yo u to l ose your wire le ss net work c onne ction .

Follow the steps below to restart the client adapter.

Restarting the Client Adapter

Step 1 Open ACU. Step 2 Select the Restart Card option from the Com mand s drop- down me nu (s ee Figure 8-4). Step 3 When promp ted to con firm your decisi on, click Yes. The driver stops the client adapter’s radio, writes

the configuration (although no parameter settings have been changed), and restarts the radio. The status bar at the bottom of the ACU screen shows the client adapter losing association and then reassociating.

Turning Your Client Adapter ’s Radio On or Off

Your client adapter’s radio can be turned on or off. Turning the radio off prevents the adapter from transmitting RF energy. You might want to turn off the client adapter’s radio when you are not transmitting data and want to conse rve battery power or when you are using a laptop on an ai rplane and want to prevent the adapter’s transmissions from potentiall y interfering w ith the opera tion of certa in devices.

When the radio is on, it periodically sends out beacons even if it i s not associated to an access point, a s required by the 802.11 specification. There fore, it is impo rtant to turn it off around devices that are susceptible to RF interference.

Note Your client adapter is not associated while the radio is off.

OL-1394-03

Follow the instructions below to turn the client adapter’s radio on or off.

• If your client a dapt er ’s radio is on, opening ACU and selecting Radio Off from the Commands
