VGA connector

Attach a Video graphics array (VGA) compatible projector or external monitor to your computer to display the computer output. For more information, see “Connecting a projector or an external monitor” on page 19.

2

Fan louver

The internal fan and louver enables air to circulate in the computer and cool the central processor.

Note: To avoid impeding airflow, do not place any obstacle in front of the fan.

3

USB 3.0 connectors

The Universal Serial Bus (USB) 3.0 connectors are used for connecting devices compatible with a USB interface, such as a USB printer or a digital camera.

Note: When you attach a USB cable to the connector, make sure that the USB mark is facing upward. Otherwise the connector might be damaged.

4

Ethernet connector

Connect your computer to a LAN with the Ethernet connector.

DANGER

To avoid the risk of electrical shock, do not connect the telephone cable to the Ethernet connector. You can only connect an Ethernet cable to this connector.

Two indicators, to the upper right and left of the connector, show the status of the network connection. When your computer connects to a LAN and a session with the network is available, the upper left indicator is steady green. While data is being transmitted, the upper right indicator blinks yellow.
