Product Introduction
GE XVR15 6U-SBC is a rugged single board computer for VME systems using 3rd Generation Intel Core i7 processors. It targets mil/aero command/control, ISR, radar/sonar, and signal processing in demanding environments.
Dual mezzanine sites (PMC/XMC) boost I/O for custom payloads while keeping slot count low. Field upgrades from older VME boards gain 20-30% compute headroom without rack redesign.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No POST LEDs | Backplane VME power fault | ❌ Low | Measure +5 V/+12 V at P0 pins with multimeter | Check bus grants and power distribution first |
| Boot hangs at BIOS | DDR3 ECC error | ✅ High | Run memtest86 from USB; check soldered DIMMs | Reseat; most ECC faults need full board swap |
| XMC/PMC not detected | Mezzanine seating issue | ✅ High | Verify torque on standoffs; probe JTAG chain | Cycle power; test mezzanine in known slot |
| Gigabit Eth link down | PHY config mismatch | ❌ Low | Ping loopback; check MDI/MDI-X switch | Update BIOS for auto-neg; cabling rarely fails |
| High junction temp alarm | Thermal throttling | ✅ Medium | Monitor via IPMI; scope fan PWM | Confirm conduction cooling if >60°C ambient |
| VMEbus timeout | Slot arbitration loss | ❌ Low | Oscilloscope DTACK lines on P1/P2 | Verify terminator packs; reload VME config |
VME SBCs rarely brick from age—bus noise or power sags cause 70% of calls. Snap bus analyzer traces before shipping back.
Frequently Asked Questions (FAQ)
Does XVR15 support quad-core in conduction-cooled builds?
Yes, i7-3615QE quad-core option works in full rugged configs. We’ve run them at 70°C junction in sonar racks—leave headroom for XMCs.
Hot-swappable into live VME chassis?
Negative. VME power sequencing fries the bus. Full power-down, ground yourself—I’ve watched sparks fly skipping this.
New surplus details? Price edge over new?
New Surplus from program cuts, 100% inbound QC’d with burn-in. No fab runs means 50% under MSRP with matching specs.
BIOS or firmware flash required on swap?
Ships with stock BIOS backup flash. Match VME64 crate profile via jumpers; OS detects CPU auto. Backup your NAND first.
Shipping and warranty?
In stock, same-day ship. 1-year on compute faults post 48-hour stress test. Returns want POST logs.
Fits standard VME64 or VPX only?
Pure 6U VME—P1/P2 compliant, no VPX bridge needed. Slots into legacy COTS chassis fine.
Failure modes in mil apps?
ECC scrubs catch most bit flips early. XMC power rails dropout after vibration—our shake table weeds them pre-ship.
