A yellow activity indicator flashes when the system is transmitting or receiving network data. (A high
volume of network traffic may make this indicator appear to be in a steady "on" state.)
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 System Setup program 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.
