Product Introduction
FORCE SPARC-CPU-5TE is a VMEbus single-board computer built around the microSPARC-II 85 MHz processor. It is designed for embedded systems and industrial control platforms that still run on legacy VME architecture.
This board is typically sourced for exact-replacement when an existing VME system loses its CPU. Buyers choose it when migrating away from the platform is not feasible and the original SPARC-based controller must be preserved.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No boot activity | Missing rack power, bad seating, or CPU board fault | ✅ High | Measure backplane rails and reseat the board | Verify power and connector condition first |
| Boot halts early | Corrupt flash, memory fault, or configuration mismatch | ✅ High | Read boot ROM messages and compare with known-good unit | Inspect flash and memory before replacement |
| SCSI device not detected | Cable fault, termination issue, or controller failure | ✅ High | Check SCSI cable, verify termination, inspect connectors | Rule out cables and terminators first |
| Ethernet link absent | Cable fault, switch port fault, or port failure | ✅ Medium | Inspect Ethernet cable, test on known-good switch port | Verify cabling and port settings first |
| Floppy not working | Cable issue, drive fault, or interface failure | ✅ Medium | Check floppy cable and test with known-good drive | Rule out external drive before replacing |
| Random resets under load | Aging components or thermal instability | ✅ High | Run soak test and monitor temperature | Replace if resets repeat during extended operation |
Contact technical support with photos of the board, rack slot, I/O cables, and boot diagnostics if the fault is unclear.
Frequently Asked Questions
Q: Is this a direct replacement for all SPARC-CPU-5TE systems?A: No. It only works as a direct replacement when the VME rack, backplane, and configuration match the original system.
Q: Can I hot-swap this board?A: No. Power down the system first. Live insertion can damage the board and backplane.
Q: Will my old configuration transfer automatically?A: Not always. If the original unit used jumpers, switches, or console settings, copy those exactly before installation.
Q: What memory configuration does this board have?A: Variants include 16 MB or 32 MB RAM. Confirm the exact memory size your system requires before ordering.
Q: Why is this discontinued?A: SPARC-CPU-5TE is an obsolete legacy product from FORCE. The manufacturer no longer produces it.
Q: How do I confirm compatibility before ordering?A: Match the part number (SPARC-CPU-5TE), verify your system uses standard VME, and confirm the I/O interfaces (SCSI-2, Ethernet, serial) match your application.
Q: Why is the price lower than new factory hardware?A: Factory-new production is unavailable. Pricing reflects limited surplus supply and test status.
