Chapter 9 Routine Procedures

Removing a Client Adapter

Removing a Client Adapter

Follow the instructions in this section to remove a PC-Cardbus card or PCI card from a computing device, when necessary.

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

Removing a PC-Cardbus Card

To remove a 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 Cardbus slot. When the card is reinserted and the computer is rebooted, your connection to the network should be re-established.

Note If you need to remove your PC-Cardbus card but do not want to shut down your computer, double-click the Unplug or Eject Hardware icon in the Windows system tray, choose the Cisco Aironet client adapter you want to remove under Hardware devices, click Stop, and click OK to close each open window. Then pull the card directly out of the card slot.

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 need to remove your PCI card.

Step 1 Completely shut down your computer.

Step 2 Remove the computer cover.

Step 3 Remove the screw from the top of the CPU back panel above the PCI expansion slot that holds your client adapter.

Step 4 Pull up firmly on the client adapter to release it from the slot and carefully tilt the adapter to slip its antenna through the opening near the slot.

Step 5 Reinstall the screw on the CPU back panel and replace the computer cover.
