Video Connector
The system uses a 15-pin high-density D-subminiature connector on the back panel for attaching a video graphics array (VGA)-compatible monitor to the
system. The video circuitry on the system board synchronizes the signals that drive the red, green, and blue electron guns in the monitor.

USB Connectors
Your system contains two USB connectors for attaching USB-compliant devices. USB devices are typically peripherals such as mice, printers, keyboards, and
system speakers.
If you reconfigure your hardware, you may need pin number and signal information for the USB connectors.

NOTICE:
Do not attach a USB device or a combination of USB devices that draw a maximum current over 500 milliamperes (mA) per channel or +5 volts
(V). Attaching devices that exceed this threshold may cause the USB ports to shut down. See the documentation that accompanied the USB devices for
their maximum current ratings.
