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 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 USB mouse or keyboard, ensure that you connect to one of the Port 1 USB connectors on the back of the computer.
  
  
• 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.
  
  

NOTICE: Before disconnecting a device from the computer, wait 10 to 20 seconds after turning off the computer to avoid possible damage to the system board.
