As a build-to-order option, the Xserve slot load computer can have a video graphics card installed. The card has a VGA connector for the video monitor.
The VGA connector is a three-row DB-15 (also called mini sub D15) connector for use with a VGA, SVGA, or XGA monitor. Figure 3-5 shows the pin configuration and Table 3-8 lists the signals and pin assignments.
