Product Introduction
Motorola MVME-376 is a VMEbus Ethernet control board used to add Ethernet networking to legacy VME-based industrial control systems. It provides a front-panel Ethernet port with status LEDs for link and activity monitoring in older automation racks.
This board is chosen when a plant needs networked communication without replacing the entire VME chassis. Buyers focus on firmware compatibility, Ethernet driver support in their RTOS, and confirmation that the physical front connector matches their cabling.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No link light on Ethernet port | Cable, switch port, or board failure | ✅ High | Swap cable, test another switch port, and verify the port LED behavior | If link still fails, the board’s Ethernet PHY may be faulty |
| Board not detected in VME crate | Poor seating or backplane issue | ✅ High | Reseat the card, inspect edge connector, and confirm correct slot voltage | Clean contacts and reseat firmly before replacing |
| Ethernet driver fails to load | Wrong driver version or firmware mismatch | ✅ High | Check VxWorks/OS-9 driver config and compare with this board’s firmware revision | Load the correct driver and firmware for MVME-376 |
| Intermittent connectivity | Power instability or backplane noise | ⚠️ Medium | Measure VME rails under load and check for voltage dips | Verify crate PSU and grounding before swapping the board |
| Status LEDs stay off | Power failure or board fault | ✅ High | Measure backplane power at the slot and check front-panel indicators | If rails are correct and LEDs are dead, the board is likely defective |
| Network packets drop repeatedly | Cable quality, switch config, or board degradation | ⚠️ Medium | Run ping tests, check switch error counters, and try another cable | Replace cable first; if drops continue, test with a known-good board |
Contact technical support with clear photos of the LEDs, the VME crate slot, and any diagnostic logs if the issue is unclear.
Frequently Asked Questions
Q: Is MVME-376 the same as 6060-0017?
A: Yes. In supplier listings, MVME-376 is often cross-referenced as 6060-0017, the VME Ethernet Control Board variant.
Q: Can I hot-swap this Ethernet board?
A: No. VMEbus boards are not designed for hot-swapping. Power down the crate before installing or removing the card to avoid backplane damage.
Q: Will my existing Ethernet driver work with this board?
A: Only if the driver and firmware version match. Legacy VME Ethernet boards often require specific driver versions for VxWorks or OS-9. Confirm the exact firmware before ordering.
Q: Why is this board cheaper than a new OEM part?
A: Because it’s obsolete and typically sold as used/tested stock. New OEM units are no longer in mass production, so prices drop but availability is limited.
Q: What condition should I expect?
A: Most units are used and tested. You’ll get a board with visible signs of prior use, but functional. Ask for test photos and status LED behavior before purchase.
Q: Does this board support Gigabit Ethernet?
A: No. It’s a legacy Ethernet controller, typically 10/100 Mbps at best. For modern networks, you may need a gateway or an upgraded VME Ethernet board.
Q: What warranty do suppliers usually offer?
A: Common warranties range from 90 days to 1 year. Check the specific supplier’s terms, as used stock often carries shorter coverage than new surplus.
