Short push
A short push is a manual depression on the 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 and initiates power-
saving mode. The Thunderbolt 3 ports remain active and are available for daisy chaining. For example, a
display that is daisy chained with the device is still available to the computer following a short push.
Short push and RAID synchroniza on/ini aliza on
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 2big Dock, 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 opera on
Removing the cable during operation can result in 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 opera on and heat management

the internal components. In addition to being exceptionally quiet, the Noctua cooling fan is temperature
controlled, which guarantees optimal heat management by adjusting the rotational speed for the
Important info regarding the ports: The LaCie 2big Dock can be connected to a computer using
the USB 3.1 port or the Thunderbolt 3 port. However, do not connect both ports to a single
computer at the same time, or connect each port to separate computers.
Important info: Always eject the LaCie 2big Dock volumes from your computer before applying
a short push.
