Power-saving mode (Thunderbolt 2 connection only)

Your LaCie d2 can conserve energy by entering power-saving mode. The hard drive within the enclosure spins

down to reduce power consumption when the LaCie d2 is in power-saving mode. Power-saving mode can extend

the life of the hard drive by sparing it from working during extended periods of inactivity. The LaCie d2 can be

placed into power-saving mode using the LED button when it is connected via the Thunderbolt 2 port. To place

the LaCie d2 into power-saving mode:

Make certain that the LaCie d2’s volumes are not being accessed.

1.

Eject the volumes (see 

Unmounting Your Hard Drive

).

2.

Apply a short press to the LED button. A short press lasts no longer than 1 second.

3.

To wake up the LaCie d2, apply another short press.

Power-saving mode: daisy chain

You can daisy chain Thunderbolt 2 technology and first generation Thunderbolt technology devices when the

LaCie d2 is in power-saving mode. Though the hard drive spins down when the LaCie d2 enters power-saving

mode, the Thunderbolt 2 signal remains constant. Therefore, daisy-chained devices continue data operations

without interruption. See 

Daisy Chain (Thunderbolt 2)

 for further details.
