Guidelines for Connecting Optional

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, use the System Setup program to enable ports on your system. See "Using the System Setup Program and UEFI Boot Manager" on page 39.
