Product Introduction
Motorola MVME2400-0331 delivers a 450 MHz PowerPC 750 CPU on VMEbus. This PMC carrier board handles embedded control in industrial racks — think telecom switches or test systems. Dual slots accept one double-wide or two single-wide PMCs. Front panel exposes Ethernet and serial debug ports.
Stock stands at 20 units now. Lead time hits 1-2 weeks for North America, UK; Southeast Asia adds 3-5 days via express. Pricing tiers drop 8% over 10 units — MOQ 1, net 30 terms standard. Backup suppliers mirror this config from VME surplus pools. In field deployments, it sustains 24/7 loads at 50 °C ambient — though your mileage may vary depending on PMC I/O draw.
Installation & Configuration Guide
Phase 1 — Pre-Installation (est. 10 min)
Power down rack. Wait 5 min for caps to discharge. Grab tools: #2 Phillips screwdriver, ESD wrist strap, label maker, camera. Export Bug firmware backup. Snap photos — DIP switches, jumpers, wire labels, rack slot mates.
Phase 2 — Removal (est. 5 min)
Label every wire pair. Release DIN rail clip. Pull module straight out — perpendicular to backplane. Check pins for bends. Photo the empty slot.
Phase 3 — Installation (est. 10 min)
ESD strap on. Match part number sticker. Copy DIP/jumper settings from your photos — J21/J22 for PMCs default open. Slide into slot until latch snaps. Torque terminals to 0.5 N·m. Double-check polarity.
Phase 4 — Power-On & Testing (est. 15 min)
Confirm 5 V ±5% at P1/P2. Power up. Watch LEDs: green RUN steady, red ERR flashes bad, amber DIAG blinks config issue. Hook up terminal via serial. Load PPCBug. Cycle I/O via PMC test loops. Run 30 min — log temp rise under 15 °C. Sign maintenance log.
Troubleshooting quick-reference
- No comms? Ping IP first, swap Ethernet cable, verify switch port up.
- ERR steady? Firmware mismatch — flash to v2.0+ via TFTP.
- Download fails? Use straight serial cable; match Bug version 8.5.
