PC Card LEDs
Before the PC Card and cable LEDs (shown here) can be used for troubleshooting,
the PC Card must be connected to the network and the driver must be installed.
Uninstalling the
Card--All Operating
Systems
Sometimes previous or unfinished installations leave problems that affect PC Card
operation. If the PC Card installation is unsuccessful for any reason, your best
course may be to remove the PC Card and its software and repeat the installation
procedures with a fresh installation of the operating system. Possible problems
may be indicated if:
• The PC Card is not working.
• Windows NT is not detecting the PC Card.
• The system issues a warning tone at startup.
If you are having any of these problems:
1 From the Control Panel>Network>Adapters , select 3Com Firewall PC Card with
10/100 LAN and click Remove .
2 Remove the PC Card from the PC Card slot.
3 Restart the computer and reinstall the PC Card.
This procedure removes the PC Card only.
