Power on

LaCie 1big Dock powers on when:

  • Connected to a computer that supports Thunderbolt 3 or USB.
  • Plugged into a live power outlet.

The LEDs blink blue while the disk spins up.

  Caution: Do not operate LaCie 1big Dock until the ambient temperature is within the specified temperature range. See System Overview.

Power off

 Follow the steps below to turn the device off:

  1. Make certain that the device’s volumes are not being accessed.
  2. Eject the 1big Dock from your computer’s operating system.
 Important info: Always safely eject 1big Dock from your computer before powering off 1big Dock. See Safely Remove Device From Your Computer.
  1. Disconnect the device from your computer.

Power-saving mode

LaCie 1big Dock can conserve energy by entering power-saving mode. Power-saving mode can extend the life of the hard drive by powering it down during extended periods of inactivity. Docking features remain active while in power-saving mode.

The device can be put into power-saving mode using the sleep button:

  1. Make certain that 1big Dock’s volumes are not being accessed.
  2. Eject the volumes from your computer’s operating system.
 Important info: Always safely eject 1big Dock from your computer before entering power-saving mode. See Safely Remove Device From Your Computer.
  1. Apply a short press (no longer than 1 second) to the sleep button. To wake up the device, apply another short press.

Power-saving mode: daisy chain

You can daisy chain Thunderbolt 3 technology devices when 1big Dock is in power-saving mode. Though the hard drive is powered off while in power-saving mode, the Thunderbolt signal remains constant. Daisy-chained devices continue data operations without interruption. See Daisy Chain, Power Delivery, and Power Pass-Through.

Power-saving mode: USB 3.0 hub

When 1big Dock is in power-saving mode, you can continue to browse and manage devices connected to the USB 3.0 hub. The connected devices continue to receive power from 1big Dock.

Power-saving mode: managed by the PC/Mac

You can initiate power-saving mode on your computer by performing one of the following:

  • Place the host computer into sleep mode.
  • Mac: Go to System Preferences > Energy Saver to enable sleep mode for hard drives.
  • Windows: Go to Control Panel > Hardware > Power Options > Choose a power plan > Change advanced power settings. Click on Hard disk and Turn off the hard disk after. Choose the time to spin down USB hard drives.

To exit power-saving mode:

Entering power-saving modeExiting power-saving mode
The host computer placed the product into power-saving mode due to inactivity. Access the device’s volume on the host computer. For example, copy files to its volume.
The computer is in sleep mode. Wake up the computer.
 Note on ejecting volumes and power-saving mode: The device enters power-saving mode when its volumes are ejected. To access the 1big Dock's hard drive again, unplug the cable from the back of the device and reconnect it.

Receiving power

1big Dock powers on automatically when it is:

  • Connected directly to a computer that is powered on.
  • Connected to a live power source via the included power supply.

Short push

A short push is a manual depression on the sleep button that lasts no longer than one second. When 1big Dock is operating, a short push spins down the hard drive and initiates power-saving mode.

 Important info: Always safely eject 1big Dock from your computer before applying a short push. See Safely Remove Device From Your Computer.

The peripheral Thunderbolt 3 port remains active and available for daisy chaining. For example, a display that is connected to 1big Dock's peripheral port is still available to the computer while the hard drive is in power-saving mode.

Long push

A long push is a manual depression on the sleep button that lasts more than four seconds. When the product is operating, a long push will cut the power to 1big 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 operation

Removing the cable connecting 1big Dock to your computer during operation can result in lost data. Safely eject 1big Dock's volumes before disconnecting the device. See Safely Remove Device From Your Computer.

Quiet operation and heat management

To reduce noise during operation, 1big Dock uses a Noctua® cooling fan to pull heat away from the internal components. The cooling fan is temperature controlled, which guarantees optimal heat management by adjusting the rotational speed for the environment. Additionally, the enclosure's metal casing dissipates heat from the hard drive, keeping it safe and prolonging its life. Since LaCie's unique design draws heat away from the internal hard drive, the external casing may be warm to the touch after extended use.

  Important info: The wide exhaust chamber on the rear of 1big Dock allows for enhanced airflow. Make sure that it is not obstructed and that there is a natural airflow across the casing.

Position and stacking

Always make certain to place 1big Dock on a flat, even surface designed to support the heat output and airflow of the hard disk enclosure. For proper heat dissipation, 1big Dock is designed to stand on its rubber feet, situated on the bottom of the enclosure. DO NOT place the enclosure on its side when it is powered on.
