2. Apply a short push to the power button. See the explanation below regarding a short push and a long
push. The status LED blinks slowly while the hard drive LEDs turn off.
It is now safe to unplug the power and Thunderbolt or USB cables from the device.
Short push
A short push is a manual depression on the LED power button that lasts no longer than one second. When
the product is operating, a short push spins down the hard drives within the enclosure. The Thunderbolt 3
ports remain active and are available for daisy chaining. This is called idle mode. For example, a display that
is daisy chained with the LaCie 6big/LaCie 12big will remain available to the computer following a short
push.
Short push and RAID synchronizaon/inializaon
Applying a short push during RAID synchronization or initialization spins down the hard drives. The RAID
synchronization/initialization continues the next time you spin the hard drives up via a short push.
Long push
A long push is a manual depression on the button that lasts more than four seconds. When the product is
operating, a long push will cut the power to the LaCie 6big/LaCie 12big, forcing it to shut down immediately.
A long push is not recommended for general use as it may result in data loss.
Removing the Thunderbolt cable during operaon
Removing the cable during operation can have serious consequences, such as lost data. If the cable is
removed while the system is synchronizing or initializing the RAID, the synchronization/initialization
continues but connection to the computer and your data is lost.
Quiet operaon and heat management
To reduce noise during operation, the LaCie 6big/LaCie 12big uses a Noctua® cooling fan to pull heat away
Important info: LaCie does not recommend applying a long push to power off the enclosure.
See the note below for long push.
Important info: Always eject the LaCie 6big/LaCie 12big volumes from your computer before
applying a short push.
