RT14 Load Error on Startup — Running Light Solid / Network Reload

Summary

If Flair reports a problem loading the RT14 at startup and the RT14 running light is solid rather than flashing, check RT14 power and the network path between PC, black box, and RT14. In the resolved case, power-cycling/restarting the system cleared it.

Symptoms

  • Startup warning appears when opening Flair.
  • Small E-stop / enable does not engage.
  • RT14 is powered but the running light is solid.
  • Error indicates a problem loading the RT14.

[CONFIRMED] Check RT14 power/network, power-cycle RT14, then reload Flair

2025-09-20 — Sasha / Stafford

  1. Confirm the RT14 is powered.
  2. Confirm the small network switch is powered.
  3. Check network cables between PC, black box, and RT14.
  4. Power-cycle the RT14.
  5. Reload Flair after the RT14 is up.
  6. The RT14 running light should flash at roughly 50 cycles/second, not remain solid.

The reporter confirmed: "Just a restart did it."
