Working Principle
The PowerPC processor manages system resources through advanced ASICs, facilitating high-speed data transfers between local ECC memory, PCI devices, and the VMEbus via the Tundra Universe bridge.
Installation Requirements
- Transition Module Prep: Refer to the MVME761 user manual for preparation of the transition module and P2 adapter.
- Fuse Verification: Check the location of the SCSI terminator power fuse (polyswitch) R4 before installation.
- Chassis Mounting: Install the complete MVME2700 VME module assembly and transition module securely into the VME chassis.
Usage Precautions
- Cable Management: Ensure no cables are pinched when replacing the chassis cover. Use shielded cables for peripheral connections to minimize radiation.
- Power Sequencing: Always follow proper power-up and power-down sequences to prevent data corruption.
