Product Line

Andover Continuum

Environment

  • BCX9640
  • i2920
  • Infinet

Cause

Electrical interference or noise being introduced into the Infinet bus.

Resolution

Removed the to i2920 controllers from the infinet.  Since these were the only controllers powered by 120 volts it seemed likely that they were a potential source of interference from the power wiring to the Infinet cable.
