Connector Description
Audio line-in connector
Used to receive audio signals from an external audio device, such as a stereo
system. When you attach an external audio device, a cable is connected between
the audio line-out connector of the device and the audio line-in connector of the
computer.
Audio line-out connector
Used to send audio signals from the computer to external devices, such as powered
stereo speakers (speakers with built-in ampliers), headphones, multimedia
keyboards, or the audio line-in connector on a stereo system or other external
recording device.
DisplayPort connector
Used to attach a high-performance monitor, a direct-drive monitor, or other devices
that use a DisplayPort connector.
DVI connector
Used to attach a Digital Video Interface cable for connection to a monitor. Also
supports connection to a VGA monitor with an optional DVI-to-VGA adapter.
Ethernet connector
Used to attach an Ethernet cable for a local area network (LAN).
Note: To operate the computer within FCC Class B limits, use a Category 5 Ethernet
