Replace an AC power supply unit (PSU) in your AFX 1K storage system when it fails or becomes faulty, ensuring that your system continues to receive the required power for stable operation. The replacement process involves disconnecting the target PSU, unplugging the power cable, removing the faulty PSU and installing the replacement PSU, and then reconnecting it to the power source.

About this task

  • This procedure is written for replacing one PSU at a time.

    Important Do not mix PSUs with different efficiency ratings. Always replace like for like.

  • The power supplies are redundant and hot-swappable; you do not have to takeover the controller to perform this task.

Steps

  1. If you are not already grounded, properly ground yourself.

  2. Identify the PSU you want to replace, based on console error messages or through the red Fault LED on the PSU.

  3. Disconnect the PSU:

    1. Open the power cable retainer, and then unplug the power cable from the PSU.

  4. Remove the PSU by rotating the handle up, press the locking tab, and then pull PSU out of the controller module.

    Caution The PSU is compact. Use both hands to support it during removal to prevent it from swinging free from the controller module and causing injury.

  5. Install the replacement PSU in the controller module:

    1. Using both hands, support and align the edges of the replacement PSU with the opening in the controller module.

    2. Gently push the PSU into the controller module until the locking tab clicks into place.

      The power supplies will only properly engage with the internal connector and lock in place one way.

      Note To avoid damaging the internal connector, do not use excessive force when sliding the PSU into the system.

  6. Reconnect the PSU cabling:

    1. Reconnect the power cable to the PSU.

    2. Secure the power cable to the PSU using the power cable retainer.

    Once power is restored to the PSU, the status LED should be green.

  7. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit. See the Part Return and Replacements page for further information.
