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
l
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 external devices while your system is turned off. Next, turn on any external devices before turning on the system (unless the
l
documentation for the device specifies otherwise).
For information about individual connectors, see your Installation and Troubleshooting Guide. For information about enabling, disabling, and configuring I/O ports
and connectors, see
