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 technology.
Daisy chaining with devices and displays that are compatible with Thunderbolt 3 technology.
Daisy chain Thunderbolt 3 devices
Thunderbolt 3 is an update of Thunderbolt 2 technology. While Thunderbolt 2 technology continues to
provide impressive transfer rates up to 20Gb/s bi-directional, Thunderbolt 3 offers improved performance
with a potential transfer rate of up to 40Gb/s bidirectional. Thunderbolt 3 technology also gives you greater
flexibility when using video and data, assigning greater throughput to the stream that carries the heavier load.
You must have a computer that supports Thunderbolt 3 to take advantage of the updates in performance and
the intelligent sharing of bandwidth.
Similar to Thunderbolt 2 technology, a single Thunderbolt 3 daisy chain can have up to seven devices,
including the computer. For example, you can daisy chain five LaCie 2big Dock enclosures on the same line
with a display.
How to daisy chain
Connect the cable to one of the interface ports on the back of LaCie 2big Dock and to your computer. The
additional port on your device can be used to daisy chain compatible Thunderbolt 3 peripherals, such as
hard drives and monitors. If you have another Thunderbolt 3 storage device, make certain to connect it to
the daisy chain before adding compatible displays or USB 3.1 (USB-C) devices. See below for an example of
the order of devices in a Thunderbolt 3 daisy chain.
1. Computer with a Thunderbolt 3 port
2. LaCie 2big Dock Thunderbolt 3 (Thunderbolt 3 ports)
3. LaCie d2 Thunderbolt 3 (Thunderbolt 3 ports)
4. LaCie Bolt 3 (Thunderbolt 3 ports)
5. LaCie Porsche Desktop (USB 3.1 (USB-C) port)
USB 3.1 (USB-C) devices can terminate a Thunderbolt 3 daisy chain and should always be the last device. It
must be connected to the secondary Thunderbolt 3 port on the preceding device. (The USB 3.1 device will
not be recognized if connected to the preceding device’s USB-C port.)
