Q: Can you confirm that the LaCie 5big is properly connected?
A: Make certain:
The power supply is properly connected to a live power source.
The Thunderbolt cable is connected to a computer that supports Thunderbolt 2 technology or first generation Thunderbolt technology.

The LaCie 5big Thunderbolt 2 turns off when I daisy chain a device.

The LaCie 5big Thunderbolt 2 is unresponsive.
Q: Have you tried to restart the system?
A: Eject the volume from the computer and shut down the LaCie 5big by applying a short push on the front button. If nothing happens after a few minutes, you can force the LaCie 5big to turn off by applying a long push (more than four seconds), then release it. Once off, restart the product by pushing and immediately releasing the front button. Note that a long push is not recommended under standard operating conditions as it may result in data loss. Once the status LED stops blinking blue, check your computer for proper connection to the LaCie 5big volumes.

Q: Is the ambient temperature too high? Is the air vent blocked? Are several fans malfunctioning?

A: The LaCie 5big Thunderbolt 2 must be connected to a computer that supports Thunderbolt 2 technology to attain Thunderbolt 2 technology transfer rates.
Q: Did you daisy chain the LaCie 5big Thunderbolt 2 with first generation Thunderbolt technology devices?
A: Thunderbolt 2 technology devices can share the same daisy chain with first generation Thunderbolt technology devices. However, the LaCie 5big Thunderbolt 2 can only reach Thunderbolt 2 transfer rates if it is connected directly to the computer with the other devices daisy-chained behind it. If your computer supports Thunderbolt 2 technology, make certain that the LaCie 5big Thunderbolt 2 is the first device on the daisy chain.
Q: Did you daisy chain the LaCie 5big Thunderbolt 2 behind a display?
