Performance Parameters
- Operating Temperature: 0°C to 55°C with forced-air cooling.
- Storage Temperature: -40°C to +85°C.
- Disk Performance: High-speed SCSI DMA transfers.
Material Composition
Industrial-grade components with enhanced disk controller circuitry and standard VME architecture.
Structural Characteristics
- Form Factor: Double-high 6U VMEbus.
- Dimensions: Standard VME 6U mechanical footprint.
Working Principle
The MPC604 processor manages disk I/O through the 53C825A SCSI controller with DMA, enabling high-speed data transfers without CPU intervention.
Installation Requirements
- Install in 6U VME chassis with adequate cooling for disk controller.
- Proper SCSI termination and cabling required for external disk devices.
Usage Precautions
- Verify SCSI termination is correct to prevent signal reflections.
- Observe ESD precautions during disk installation.
- Ensure power supply can handle disk spin-up current.
