the wall outlet, and allow the internal system components to cool
before touching.
!WARNING: To reduce the risk of electrical shock, fire, or damage to
the equipment, do not plug telecommunications/telephone connectors

When to Reconfigure the Computer
System configuration is the process of specifying the devices and
programs that make up a computer system. When you add or remove
optional equipment, the computer must be reconfigured to recognize
these changes.
Windows 95 and later operating systems automatically recognize all
Plug and Play devices installed. However, if the device is not a Plug and
Play device or is not automatically detected after installation, follow
these instructions:
 In Windows 95 and later operating systems, select the Add New
Hardware icon in the Control Panel and follow the instructions on
the screen.
 To reconfigure the computer in Windows NT version 4.0, use the
software utility provided with the newly installed hardware.
