ABB FI820F 3BDH000031R1总线模块
LAN1 10/100BaseTx指示是10BaseT还是100BaseTx模式。黄色LED指示10BaseT，绿色LED指示100BaseTx。LAN2活动表示以太网处于活动状态（黄色LED）。LAN2 10/100BaseTx指示是10BaseT还是100BaseTx模式。黄色LED指示10BaseT，绿色LED指示100BaseTx。此外，前面板LED用于指示VMIVME-7750可能出现的各种操作状态模式。下表总结了这些指示。电路板处于重置状态“LAN 10BaseT/100BaseT”LED快速交替黄/绿，红色“重置”LED点亮。CPU不存在绿色“电源”LED亮起，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。
LAN1 10/100BaseTx Indicates whether 10BaseT or
100BaseTx mode. Yellow
LED indicates 10BaseT, and
Green LED indicates
100BaseTx.
LAN2 Active Indicates the Ethernet is
active, (Yellow LED).
LAN2 10/100BaseTx Indicates whether 10BaseT or
100BaseTx mode. Yellow
LED indicates 10BaseT, and
Green LED indicates
100BaseTx.In addition, the front-panel LEDs are used to indicate various modes of operational
status that can occur with the VMIVME-7750. The table below is a summary of these
indications.Board is in Reset “LAN 10BaseT/100BaseT” LED rapidly alternates
Yellow/Green and the Red “Reset” LED is illuminated.
CPU Not Present Green “Power” LED is illuminated and the Red
“Reset” LED flashes at a rapid rate.
VME SYSFAIL Red “B” LED illuminates with each VME SYSFAIL
‘seen’ on the bus. The LED will remain on as long as
the failure lasts.
VRM Failure Green “Power” LED is off and the Red “Reset” LED
flashes at a rapid rate.
