Receiving power

The LaCie 2big powers on automatically when it meets the following two conditions:

  • Connected directly to a computer via the USB port. The computer must be powered on.
  • Connected to a live power source via the included power supply.

Note on the USB 3.0 connection: The LaCie 2big can be connected to a USB 2.0 port on your computer. To take advantage of SuperSpeed USB 3.0 transfer rates, you must connect the enclosure to a computer with a USB 3.0 port.

LED button

The LED is also a button to turn the LaCie 2big on or off. Always eject the LaCie 2big’s volumes before turning it off or placing it in idle and power-saving modes.

  • Long press. Push the LED for two seconds to power off the enclosure.
  • Short press. Push the LED for one second to: power on the device; place the device into idle mode (Thunderbolt 2 only, see below); wake the device from idle mode (Thunderbolt 2 only, see below); or, place the device into power-saving mode (USB 3.0, see below).

The LaCie 2big powers on automatically when it is connected to a computer that is also powered on. However, if you turn the LaCie 2big off using a long press, you must turn the device on manually.

 

Idle mode (Thunderbolt 2 only)

You can use the LED button to enter idle mode:

  1. Unmount the volumes (see Unmounting Your Drive).
  2. Apply a short press to the LED button.

The enclosure will stop sending power to the hard drives. Idle mode allows you to daisy chain Thunderbolt 2 devices and first generation Thunderbolt devices even when the hard drives are not active.

To exit idle mode, apply a short press to the LED button. The hard drives spin up and the volumes should appear on the desktop.

Technical note: The LaCie 2big must receive power via its power cable to allow for a daisy chain in idle mode.

Power-saving mode (USB 3.0)

The LaCie 2big will stop sending power to the hard drives when it enters power-saving mode. To spin down the hard drives, apply a short press to the LED button. Perform the same action to exit power-saving mode.
