Guidelines for Connecting External Devices
•
Turn off power to the system and external devices before attaching a new
external device. Turn on any external devices before turning on the system
(unless the documentation for the device specifies otherwise).
•
Ensure that the appropriate driver for the attached device has been
installed on the system.
•
If necessary to enable ports on your system, use the System Setup program.
See "Entering the System Setup Program" on page 54.
