GE FANUC VME‑7807RC‑414001 VMEbus Single Board Computer

The GE FANUC VME‑7807RC‑414001 is a high‑performance 6U VMEbus single‑board computer, originally developed by VMIC under GE Fanuc Embedded Systems division. Equipped with Intel Pentium‑M processor, it delivers fan‑less embedded computing power for VME‑based turbine control, industrial automation and real‑time data acquisition systems. It acts as main processing unit to run application software and communicate with other VME peripheral modules via backplane bus.

This 6U Eurocard SBC supports bootable CompactFlash storage, dual gigabit Ethernet, multiple serial ports and PMC mezzanine expansion slot. On‑board hardware watchdog timer and battery‑backed NVRAM ensure reliable continuous operation under harsh industrial conditions. It plugs into standard VME chassis backplane for power and bus interconnection. As obsolete aftermarket spare parts, it is widely used for maintenance, replacement and retrofit of GE turbine and legacy VME industrial control equipment.

FAQ

1. Q: Can GE FANUC VME‑7807RC‑414001 work independently without matching VME chassis and backplane?
   A: It must be installed in standard 6U VME chassis and cooperate with VME backplane bus, cannot operate as standalone hardware.
2. Q: What are typical module failure symptoms?
   A: System boot failure, VME‑bus communication abort, Ethernet port offline, watchdog frequent reset, CompactFlash boot error.
3. Q: How to complete commissioning and diagnosis?
   A: Inspect VME chassis power supply and backplane contact; check boot log, network status and hardware registers through system console interface.
