Audio connectors Use the audio connectors to connect external audio equipment to the computer. The following illustration shows the audio connectors. Mic Line out Line in (pink) (green) (blue) Mic There are two microphone connectors on the front and one on the rear of the computer. Connect a microphone to this connector to record sounds onto the hard disk or to use speech-recognition software. Line out There are two line-out connectors, one on the front and one on the rear of the computer. The computer sends audio signals through this connector to powered speakers with built-in amplifiers, headphones, a multimedia keyboard, or the audio line-in connector on a stereo system. The internal speaker in the computer is disabled when a device is attached to this connector. Line in There is one line-in connector on the rear of the computer. The computer receives audio signals through this connector from an external audio device. Auxiliary-device (pointing-device) connector There is one auxiliary-device connector on the rear of the computer. Use this connector to connect a mouse or other pointing device. The following illustration shows an auxiliary-device connector. 6 4 2 5 3 1 Ethernet (RJ-45) connector There is one Ethernet connector on the rear of the computer. Use this connector to connect the computer to a 10-Mbps, 100-Mbps, or 1000-Mbps network. The following illustration shows an Ethernet connector. Activity LED (green) Link LED (green) 8 1 Connect a Category 3, 4, or 5 unshielded twisted-pair (UTP) cable to this connector. The 100BASE-TX and 1000BASE-T Fast Ethernet standards require Category 5 or higher cabling. The Ethernet connector has one LED that indicates Ethernet-link status. When this LED is lit, it indicates that there is an active connection on the Ethernet port. Activity between the computer and the network is indicated by the Ethernet transmit/receive activity LEDs on the front and rear of the computer (see "Controls, LEDs, and connectors" on page 9).
