Connecting Devices

When you connect external devices to your computer's back panel, follow
these guidelines:
• Check the documentation that accompanied the device for specific
installation and configuration instructions.
For example, you must connect most devices to a particular
input/output (I/O) port or connector to operate properly. Also, external
devices like a printer usually require you to load device drivers before
they will work.
• When connecting a Universal Serial Bus (USB) mouse or keyboard,
ensure that you connect to one of the Port 1 USB connectors.
• Always attach external devices while your computer is turned off. Then
turn on the computer before turning on any external devices, unless
the documentation for the device specifies otherwise.
