Upgrade Failure Instructions

If the module detects a problem immediately after a firmware upgrade, a System Recovery Upgrade Required fault is triggered. In this event, you should activate the alternate firmware and attempt the upgrade again. If this second attempt fails, use the Failsafe mode to install the new firmware.

See your application module instructions for details about failsafe mode.
