A dual-colored link integrity indicator, which lights up green when there is a good connection between a
10-Mbps network and the NIC, or it lights up orange when there is a good connection between a 100-
Mbps network and the NIC. When the green indicator is off, the computer is not detecting a physical
connection to the network.
Audio Connectors
You can use the microphone jack to attach a standard personal computer microphone. Connect the audio
cable from the microphone to the microphone jack. The microphone input is a monaural source with
maximum signal levels of 89 millivolts root-mean-squared (mVrms).
You can use the line-out jack to attach most computer speakers. The line-out jack is amplified, so speakers
with integrated amplifiers are not required. Connect the audio cable from the speakers to this jack.
You can use the line-in jack to attach record/playback devices such as cassette players, CD players, and
VCRs. Connect the line-out cable from any of these devices to the line-in jack on the back of your computer.
Video Connector
The system uses a 15-pin high-density D-subminiature connector on the back panel for attaching a VGA-
compatible monitor to your system.
Serial Port Connectors
The serial ports use 9-pin D-subminiature connectors on the back panel. These ports support devices such
as external modems or plotters that require serial transmission (sending one bit of data at a time over one
line).
The default designations for these integrated serial ports are COM1 for serial port 1 and COM2 for serial port
2. Port designations are used in software installation procedures to identify the port used by a device—for
example, specifying the port used by a modem when installing communications software.
The system contains a reconfiguration feature to reassign the serial port's designation if you add an
expansion card containing a serial port using this designation.
If you set the system’s integrated serial ports to Auto in the
and add an expansion
card containing a serial port configured to a specific designation, the computer automatically maps (assigns)
the integrated ports to the appropriate COM setting as necessary.
Before you add a card with a serial port, check the documentation that accompanied your software to make
sure that the software can be mapped to the new COM port designation.
Keyboard Connector
Your system uses a PS/2-style keyboard. The keyboard cable attaches to a 6-pin miniature DIN connector
on the back panel of your computer.
Network Cable Requirements
Your computer's NIC connector (an RJ45 connector located on the back panel) is designed for attaching an
unshielded twisted pair (UTP) Ethernet cable. Press one end of the UTP cable into the NIC connector until
