==== Power Button ====

The LED button may be used to conserve energy if you do not expect to use the disks for an extended period of time. To reduce power consumption:

  - Unmount the partition(s) (see [[unmounting|]])
  - Press the LED button

The enclosure will stop sending power to the disks. Please note that the enclosure will maintain the daisy chain with other Thunderbolt devices even when the drives have been powered down.

To power on the drives, press the LED button. The partition(s) will appear on the desktop.
