Quality Control Process
We inspect every industrial automation unit rigorously. First, we verify the 800MHz PowerPC 750 boots and executes POST successfully. Next, we run memory diagnostics on the SDRAM to detect bit errors. We validate both 10/100 Ethernet ports for proper link and throughput. PCI and PMC expansion slots receive functional checks with known-good mezzanine cards. Finally, we pack the SBC in anti-static shielding.
Replacement Pitfall Guide
❗ Verify PMC vs PCI Mode. This SBC supports both PMC and PCI expansion via jumpers. Wrong settings disable the expansion slot or break rear I/O routing. Check the manual before installing daughter cards.
❗ Check Backplane VME Compatibility. The MVME2301 requires proper VMEbus signaling. Older backplanes may limit bandwidth or cause arbitration errors. Confirm your chassis specs first.
❗ USB 2.0 Power Draw. The onboard USB 2.0 ports draw significant current. Overloading them causes voltage drops on the 5V rail. Use powered hubs for high-draw peripherals.
❗ Ethernet PHY Configuration. Dual 10/100 ports require correct firmware settings. Auto-negotiation failures cause link drops. Verify BSP configuration matches your network setup.
Keep these in mind and you’ll cut 90% of rework time.
