Insert and Remove the 1784-PCD Card 7-3
Publication 1784-IN029C-EN-P - June 2001
Multiple Tones
If you insert multiple PC cards, you may hear more than one tonal notification per
card. Windows 95/98/Me, and 2000 detect devices during the power-up process,
and adjust the device resources accordingly. This results in sounding multiple
tones. When the system changes settings, for example, when a card is removed, the
tones will sound again for each change.
Remove the PCD Card
On most computers, you press the release button and remove the card from the
slot. If this is not applicable to your computer, follow the instructions specified in
its user manual.
You hear multiple tones for each card that you remove, if your system is configured
properly. These tones indicate the card is now disabled.
IMPORTANT
Do not remove the card under power on a Windows NT system.
IMPORTANT
Before removing the PCD card, you must first stop
communication to it, which also stops the card. Refer to the
appropriate Chapter for your operating system for procedures for
stopping the card.
IMPORTANT
You should stop any software communicating with the card
before removing the PCD card. If you do not do this, the stray
processes may affect the system’s performance, potentially
halting the system.
