Working Principle
The PowerPC processor accesses the 256MB ECC memory pool via the RAM200 module, utilizing DMA channels to offload data transfers from the CPU.
Installation Requirements
- Install in a 6U VME chassis with forced-air cooling.
- Ensure adequate clearance for heat dissipation from memory modules.
Usage Precautions
- Handle with ESD protection.
- The higher memory density requires careful handling.
- Verify power supply can handle the increased load.
