Working Principle: The MVME2400 operates as the central processing unit of a VMEbus system. The PowerPC 750 processor executes application code stored in Flash memory, accesses data in ECC SDRAM, and communicates with VMEbus peripherals and PMC expansion modules through the PCI bus and VME interface. The on-board debug monitor provides firmware-level diagnostics and boot capabilities. Installation Requirements:
- Install in a standard 6U VMEbus chassis with compatible backplane
- Align P1 and P2 connectors with the backplane and seat the board fully
- Secure using front-panel ejector levers and mounting screws
- Connect Ethernet, serial, and PMC I/O cables as required
- Configure boot parameters via the debug monitor
Usage Notes:
- Observe ESD precautions when handling the board
- Verify VMEbus chassis power is off before insertion or removal
- Replace the NVRAM backup battery periodically to maintain RTC and stored data
- Ensure adequate chassis cooling for the specified operating temperature range
- Use compatible PMC modules to avoid electrical or mechanical conflicts
