This article has been archived and is no longer updated by Apple.
  1. Make sure the correct firmware update has been downloaded to the Xserve by using Software Update, for example. This can be done remotely with Apple Remote Desktop (ARD) or from the command line.
  2. ssh into the target server.
  3. Type sudo -s and enter the server's root password at the prompt.
  4. Type the following and press Return: cd /Applications/Utilities
  5. To start the firmware update installation, type the following on a single line:
    ./Xserve\ EFI\ Firmware\ Update.app/Contents/Resources/RemoteEFIUpdater -shutdown
    Note: If you have more than one volume, or the application is not in the default location, you must specify the absolute path:
    (/Volumes/Server\ HD/Xserve\ EFI\ Firmware\ Update.app/Contents/Resources/RemoteEFIUpdater -shutdown)
  6. Press the 'Y' key when you see this message:
    Your firmware needs to be updated. Your Xserve will need to be shut down, and manually powered up to complete the update process. Instructions will be provided.
    Run this program with option '-h' for help.
    Enter 'y' to confirm you want to update your firmware.
  7. Wait for the remote server to shut down.
  8. Press and hold the power button on your Xserve until the 'system activity lights' flash repeatedly.
  9. Release the power button, your Xserve's firmware will be flashed.
    Flashing will take a few minutes.
    Warning
    : DO NOT INTERRUPT the Xserve while flashing. Your Xserve will automatically restart once flashing is complete.
  10. ssh into the target server.
  11. Type sudo -s and enter the server's root password at the prompt.

  14. If your firmware has been properly updated, you should see the following message:
