ABB EI813F 3BDH000022R1现场总线模块
VMIVME-7750为以下各项提供后端I/O支持：PMC、IDE驱动器和软盘驱动器。通过使用后面板过渡板（如VMIACC-0562）访问这些信号，该板终止于行业标准连接器。VMIVME-7750的前面板连接器（包括连接器引脚和方向）在附录A中定义。后面板连接在相应的后面板过渡实用板安装指南中定义。有关VMIC提供的兼容后面板传输实用程序板，请参阅VMIVME-7750产品规范。开关重置-允许从前面板重置系统。LED R重置-重置条件下亮起（红色LED）。LED P电源-指示板何时通电（绿色LED）。该LED还通过缓慢闪烁来指示节流。LED I IDE指示灯-指示IDE活动何时发生（黄色LED）.B引导-指示BIOS引导正在进行中。当LED熄灭时，CPU已完成POST并准备就绪（红色LED）。引导完成后，此LED将指示任何VME“SYSFAILS”。LAN1活动表示以太网处于活动状态（黄色LED）。
The VMIVME-7750 provides rear I/O support for the following: PMC, IDE drive and
floppy drive. These signals are accessed by the use of a rear-panel transition board
such as the VMIACC-0562, which terminate into industry standard connectors.
The front panel connectors, including connector pinouts and orientation, for the
VMIVME-7750 are defined in Appendix A. Rear panel connections are defined in the
appropiate rear panel transition utility board Installation Guide. See the
VMIVME-7750 product specification for compatible rear panel transistion utility
boards offered by VMIC.Switch Reset - Allows the system to
be reset from the front panel.
LED R Reset - Lights during reset
condition, (Red LED).
LED P Power - Indicates when
power is applied to the
board, (Green LED). This
LED also indicates throttling
by blinking slowly.
LED I IDE Indicator - Indicates
when IDE activity is
occurring, (Yellow LED).B Booting - Indicates BIOS Boot
is in progress. When LED is
off, CPU has finished POST
and is ready, (Red LED).
Once booting has completed,
any VME ‘SYSFAILS’ will be
indicated by this LED.
LAN1 Active Indicates the Ethernet is
active, (Yellow LED).
