Powering off the Storage Device

Powering off the Storage Device

Respect the correct power-off sequence when you power off the storage device especially for replacing cabinet subracks or removing power link failures.


No service is running on the storage device.


The correct power-off sequence is: stopping services running on the storage device → holding down the power button for 5 seconds for the controller enclosure to be powered off → disconnecting the controller enclosure and disk enclosures from their external power supplies.


When you want to power off a storage system with four or more controllers, press the Power button of any controller enclosure that houses the first four controllers for five seconds to power off the entire system.

To power off the storage device, you can either press and hold the controller enclosure's power button for 5 seconds or execute power-off operations on DeviceManager. This document exemplifies how to power off the storage device using DeviceManager.


  1. Log in to DeviceManager.
  2. Choose Settings > Power Off Device.
  3. Confirm the information in the displayed Danger dialog box and enter the password of the currently logged in user. Then select I have read and understand the consequences associated with performing this operation.

    If you enter the wrong password three times in succession within 5 minutes, the current user will be logged out and exit DeviceManager.

  4. Click OK.

    The Success dialog box is displayed, indicating that the operation succeeded.

  5. Click OK. You have powered off the storage device.
  6. Disconnect all power supplies from the controller enclosures and disk enclosures to power off the storage system.
