Daisy Chain and Power Delivery
Use the two Thunderbolt 3 ports on the LaCie 2big Dock for:
Direct connection to a computer that is compatible with Thunderbolt 3 and Thunderbolt 4 technology.
Daisy chaining with devices and displays that are compatible with Thunderbolt technology.
How to daisy chain
The peripheral Thunderbolt 3 port on 2big Dock can be used to daisy chain compatible Thunderbolt
peripherals, such as hard drives and monitors. If you have another Thunderbolt storage device, make certain
to connect it to the daisy chain before adding compatible displays or USB devices. See below for an
example of the order of devices in a Thunderbolt daisy chain.
1. Computer with a Thunderbolt 3 port.
2. LaCie 2big Dock (connected to computer via host Thunderbolt 3 port).
3. LaCie d2 Thunderbolt 3 (connected to 2big Dock's peripheral/daisy chain Thunderbolt 3 port).
4. Second LaCie d2 Thunderbolt 3 (connected to first d2 via Thunderbolt 3 port).
5. LaCie Rugged SSD (connected to second d2 via Thunderbolt 3 port).
USB devices can terminate a Thunderbolt daisy chain and should always be the last device. It must be
connected to the secondary Thunderbolt port on the preceding device. (The USB device will not be
recognized if connected to the preceding device’s USB-C port.)
