Using Backup App

Allen-Bradley · PowerFlex 750

¿Qué significa 125 ?

The primary application firmware flash operation failed, and the drive is currently running on a backup application. This signifies a critical issue with the primary firmware's integrity. The drive is operating in a degraded state and requires immediate re-flashing of the application firmware to ensure full functionality and reliability.

Causas comunes

  • Primary application firmware corruption due to power loss during a flash operation.
  • Failed or incomplete firmware update preventing the primary application from booting correctly.
  • Degradation of the flash memory sector where the primary application resides.
  • An internal system error forcing a fallback to the known good backup application.

    2. Attempt to re-flash the primary application firmware using the appropriate programming tool (e.g., DriveExplorer) and a verified firmware file.

  3. 3

    3. Ensure a stable power supply (within specified voltage tolerance) to the drive throughout the firmware flashing process.

  4. 4

    4. After a successful flash, perform a drive power cycle and verify that the drive boots into the primary application.
