Auxiliary-Device (Pointing-Device) Connector; Ethernet (Rj-45) Connector; Ieee 1394 (Firewire) Connector (Some Models) - IBM IntelliStation M Pro User Manual

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 the computer is
disabled when a device is attached to this connector.
Mic
There is one microphone connector on the front of the computer. Connect a
microphone to this connector to record sounds onto the hard disk or to use
speech-recognition software.

Auxiliary-device (pointing-device) connector

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
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 and LEDs" on
page 9).

IEEE 1394 (FireWire) connector (some models)

There is one 4-pin Institute of Electrical and Electronics Engineers (IEEE) 1394
(FireWire) connector on the front of the computer and one 6-pin IEEE 1394
(FireWire) connector on the rear of the computer. Use these connectors to connect
IEEE 1394 (FireWire) devices. The following illustrations show the IEEE 1394
(FireWire) connectors.
