Connecting External Devices
When connecting external devices to your system, follow these guidelines:
• Most devices must be connected to a specific connector and device drivers must be installed before the
device operates properly. (Device drivers are normally included with your operating system software or
with the device itself.) See the documentation that accompanied the device for specific installation
and configuration instructions.
• Always attach an external device while your system and the device are turned off. Next, turn on any
external devices before turning on the system (unless the documentation for the device specifies
otherwise).
