各种操作状态模式
前面板LED用于指示GFD563A102可能出现的各种操作状态模式。下表总结了这些指示。状态指示状态指示板处于重置“LAN 10BaseT/100BaseT”LED快速交替黄色/绿色，红色“重置”LED点亮。CPU不存在绿色“电源”LED点亮，红色“重置”LED快速闪烁。VME SYSFAIL红色“B”LED亮起，总线上的每个VME SYSFAIL“可见”。只要故障持续，LED将一直点亮。VRM故障绿色“电源”LED熄灭，红色“重置”LED快速闪烁。节流激活（非故障模式）绿色“电源”LED缓慢闪烁。如果尚未从BIOS设置屏幕中选择CPU节流，但每次尝试启动时，绿色LED都会持续闪烁（但不会运行），请清除CMOS或将产品返回VMIC进行维修。正常操作LED R=关闭（不重置）LED P=打开（电源正常）LED I=关闭，或闪烁（IDE活动）LED B=关闭（启动完成）
功能介绍
GFD563A102是一款基于英特尔奔腾III处理器的单板计算机，与现代工业标准桌面系统兼容。因此，GFD563A102保留了行业标准内存和I/O映射以及标准中断架构。本节中描述的集成外设（如串行端口、USB端口、IDE驱动器、软盘驱动器、视频控制器和以太网控制器）都与类似设备的桌面系统具有相同的内存映射，确保与现代操作系统兼容。以下章节介绍了GFD563A102的标准功能。
Various operation state modes
The front panel LED is used to indicate various possible operation state modes of GFD563A102. The following table summarizes these instructions. Status indication The status indicator board is in reset "LAN 10BaseT/100BaseT" LED fast alternating yellow/green, and the red "reset" LED is on. There is no green "power" LED on the CPU, and the red "reset" LED flashes quickly. The VME SYSFAIL red "B" LED illuminates and each VME SYSFAIL on the bus is "visible". The LED will remain illuminated as long as the fault persists. VRM fault The green "power" LED is off, and the red "reset" LED flashes quickly. Throttle active (non fault mode) green "power" LED flashes slowly. If you have not selected CPU throttling from the BIOS setup screen, but the green LED will continue to flash (but will not run) every time you try to start, clear CMOS or return the product to VMIC for repair. Normal operation LED R=off (not reset) LED P=on (normal power supply) LED I=off, or flashing (IDE activity) LED B=off (startup completed)
Function introduction
GFD563A102 is a single board computer based on Intel Pentium III processor, which is compatible with modern industrial standard desktop system. Therefore, GFD563A102 retains the industry standard memory and I/O mapping as well as the standard interrupt architecture. The integrated peripherals described in this section (such as serial ports, USB ports, IDE drives, floppy disk drives, video controllers, and Ethernet controllers) have the same memory mapping as desktop systems of similar devices, ensuring compatibility with modern operating systems. The following sections describe the standard functions of GFD563A102.
