Microphone
There are two microphone connectors, one 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 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.
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 your computer is
disabled when any device is attached to either the front or rear line-out connector.
Connecting devices to the front line-out connector disables the rear line-out
connector.
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.

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 two LEDs, one that indicates Ethernet-link status and
one that indicates transmit/receive activity. When the Ethernet-link status 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 and indicators” on
page 9).
IEEE 1394 (FireWire) connectors
There is one 4-pin IEEE 1394 connector on the front of the computer and one 6-pin
IEEE 1394 connector on the rear of the computer. Use these connectors to connect
IEEE 1394 devices. The following illustrations show the IEEE 1394 connectors.
