Auxiliary-Device (Pointing-Device) Connector; Ethernet (Rj-45) Connector; Ieee 1394 (Firewire) Connectors (Some Models) - IBM 6219 - IntelliStation M - Pro Hardware Maintenance Manual

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 this connector.
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. There are two microphone connectors,
one on the front and one on the rear of the computer.

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.

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.
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 indicators"

IEEE 1394 (FireWire) connectors (some models)

There is one 4-pin 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.
