Power up controller (simplex)

Power up the controller shelf to confirm that it is working correctly. Then, you can collect support data and resume operations.

About this task

Perform this task only if your storage array has one controller.


  1. Turn on the two power switches at the back of the controller shelf.
    • Do not turn off the power switches during the power-on process, which typically takes 90 seconds or less to complete.
    • The fans in each shelf are very loud when they first start up. The loud noise during start-up is normal.
  2. As the controller boots, check the controller LEDs and seven-segment display.
    • The seven-segment display shows the repeating sequence OS, Sd, blank to indicate that the controller is performing Start-of-day (SOD) processing. After a controller has successfully booted up, its seven-segment display should show the tray ID.
    • The amber Attention LED on the controller turns on and then turns off, unless there is an error.
    • The green Host Link LEDs turn on.
      Note: The figure shows an example controller canister. Your controller might have a different number and a different type of host ports.

  3. Confirm that the controller's status is Optimal, and check the controller shelf’s Attention LEDs.
    If the status is not Optimal or if any of the Attention LEDs are on, confirm that all cables are correctly seated, and check that the battery and the controller canister are installed correctly. If necessary, remove and reinstall the controller canister and the battery.
    Note: If you cannot resolve the problem, contact technical support.
  4. Collect support data for your storage array using SANtricity System Manager.
