Inserting and Removing a Client Adapter

B E TA D R A F T - C I S C O C O N F I D E N T I A L

Inserting and Removing a Client Adapter

This section provides instructions for inserting and removing PC cards, PC-Cardbus cards, and PCI cards. Instructions are not provided for LM cards and mini PCI cards because they are pre-installed inside computing devices and are not meant to be installed or removed by the user.

Caution These procedures and the physical connections they describe apply generally to conventional PC card slots, Cardbus slots, and PCI expansion slots. In cases of custom or nonconventional equipment, be alert to possible differences in PC card slot, Cardbus 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.

Inserting a PC Card or PC-Cardbus Card

Step 1 Before you begin, examine the card. One end has a dual-row, 68-pin connector. The card is keyed so it can be inserted only one way into the PC card slot or Cardbus slot.

Note The PC card slot or Cardbus slot is on the left or right side of the computer, depending on the model.

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

•Windows NT – Turn off your computer, follow the remaining steps in this section to insert the card, and reboot your computer.

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 facing 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).

Step 4 Go to the “Installing the Driver” section on page 3-3 to install the driver for your computer’s operating system.

Inserting a PCI Card

Step 1 Turn off the PC and all its components.

Step 2 Remove the computer cover.

Note On most Pentium PCs, PCI expansion slots are white. Refer to your PC documentation for slot identification.

Step 3 Remove the screw from the top of the CPU back panel above an empty PCI expansion slot. This screw holds the metal bracket on the back panel.

Caution Static electricity can damage your PCI card. Before removing the adapter from the anti-static packaging, discharge static by touching a metal part of a grounded PC.

Step 4 Examine the PCI card. The antenna connector and the LEDs face out of your computer and are visible when you put the cover back on. The bottom edge of the card is the connector you will insert into an empty expansion slot in your computer. See Figure 8-2.

Step 5 Tilt the card to allow the antenna connector and LEDs to slip through the opening in the CPU back panel.

Step 6 Press the card into the empty slot until the connector is firmly seated.

Caution Do not force the card into the expansion slot as this could damage both the card and the slot. If the card does not insert easily, remove it and reinsert it.

Step 7 Reinstall the screw on the CPU back panel and replace the computer cover.

Step 8 Attach the 2-dBi antenna to the card’s antenna connector until it is finger-tight. Do not overtighten.

Step 9 For optimal reception, position the antenna so it is straight up.

Step 10 Boot up your PC.

Removing a Client Adapter

Follow the instructions in one of the sections below to remove a PC card, PC-Cardbus card, or PCI card from a computing device, when necessary.

Removing a PC Card or PC-Cardbus Card

To remove a PC card or PC-Cardbus card after it is successfully installed and configured (such as when your laptop is to be transported), completely shut down your computer and pull the card directly out of the PC card slot or Cardbus slot. When the card is reinserted and the computer is rebooted, your connection to the network should be re-established.

Removing a PCI Card

Because PCI client adapters are installed inside desktop computers, which are not designed for portable use, you should have little reason to remove the adapter. However, instructions are provided below in case you ever need to remove your PCI card.

Step 1 Completely shut down your computer.

Step 2 Disconnect the client adapter’s antenna.

Step 3 Remove the computer cover.

Step 4 Remove the screw from the top of the CPU back panel above the PCI expansion slot that holds your client adapter.

Step 5 Pull up firmly on the client adapter to release it from the slot and carefully tilt the adapter to allow it to clear the opening in the CPU back panel.

Step 6 Reinstall the screw on the CPU back panel and replace the computer cover.

Upgrading the Firmware

B E TA D R A F T - C I S C O C O N F I D E N T I A L

Upgrading the Firmware

The client adapter is shipped with the firmware installed in its Flash memory; however, a more recent version of the firmware may be available from Cisco.com. Cisco recommends using the most current version of radio firmware. Follow the instructions in this section to determine the version of your client adapter’s firmware and to upgrade it if a more recent version is available from Cisco.com.

Determining the Firmware Version

Follow the instructions in this section to determine if you need to upgrade the client adapter’s firmware.

Step 1 To determine the version of firmware that your client adapter is currently using, open ACU; then click the Status icon or select Status from the Commands drop-down menu. The Status screen displays the current version of your adapter’s firmware in the Firmware Version field.

Step 2 To determine the latest firmware version available on Cisco.com, follow the steps below:

Restarting the Client Adapter

B E TA D R A F T - C I S C O C O N F I D E N T I A L

Deleting the ACU Icon from the Desktop

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 icon, click 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 adapter 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 Restarting the client adapter may cause you to lose your wireless network connection.

Follow the steps below to restart the client adapter.

Step 1 Open ACU.

Step 2 Select the Restart Card option from the Commands drop-down menu (see Figure 8-4).

Step 3 When prompted to confirm your decision, 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 conserve battery power or when you are using a laptop on an airplane and want to prevent the adapter’s transmissions from potentially interfering with the operation of certain devices.

When the radio is on, it periodically sends out beacons even if it is not associated to an access point, as required by the 802.11 specification. Therefore, it is important to turn it off around devices that are susceptible to RF interference.

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

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

•If your client adapter’s radio is on, opening ACU and selecting Radio Off from the Commands drop-down menu (see Figure 8-4) turns the radio off. The status bar at the bottom of the ACU screen indicates that the radio is turned off.

•If your client adapter’s radio is off, opening ACU and selecting Radio On from the Commands drop-down menu (see Figure 8-4) turns the radio on.

Note If you are prompted to reboot your computer, Cisco recommends that you select the Yes, I want to restart my computer now option.

Step 5 Click Finish. The repair is complete. All of the selections you made during the previous installation are maintained.

Client Adapter Recognition Problems

Note This section does not apply to mini PCI cards.

If your client adapter is not being recognized by your computer’s PCMCIA adapter, check your computer’s BIOS and make sure that the PC card controller mode is set to PCIC compatible.

Note A computer’s BIOS varies depending on the manufacturer. For support on BIOS-related issues, consult your computer’s manufacturer.

Resolving Resource Conflicts

Note This section does not apply to the mini PCI cards.

If you encounter problems while installing your client adapter on a computer running a Windows operating system, you may need to specify a different interrupt request (IRQ) or I/O range for the adapter.

The default IRQ for the client adapter is IRQ 10, which may not work for all systems. Follow the steps for your specific operating system to obtain an available IRQ.

During installation the adapter’s driver installation script scans for an unused I/O range. The installation can fail if the I/O range found by the driver installation script is occupied by another device but not reported by Windows. An I/O range might not be reported if a device is physically present in the system but not enabled under Windows. Follow the steps for your specific operating system to obtain an available I/O range.
