Troubleshooting
How is the unit able to support up to 6 Thunderbolt devices?
The hub's three Thunderbolt 4 ports are capable of directly supporting
three Thunderbolt-compatible devices and can also cascade to up to
six levels. This includes Thunderbolt docks and adapters (such as the
Tripp Lite MTB3-Series) that allow you to connect peripherals such
as hard disks, RAID memory, additional USB ports and more. The
MTB4-HUB3-01 acts as the first level in the chain and can cascade
an additional five levels vertically, with many more devices connecting
horizontally. The dock supports 40 Gbps Thunderbolt 4 data transmission
that is shared among the three ports and all connected peripherals and
displays. For instance, if both displays are in use, roughly 32 Gbps is
diverted to the displays, leaving 8 Gbps for the final port and anything
connected to it.
How does the smart power charging affect devices connected to
the unit?
The MTB4-HUB3-01 features a 20V 5A (100W) power input and is
capable of providing up to 60W to charge the host computer. Each
Thunderbolt 4 port is capable of providing up to 15W to connected
peripherals, and the USB 3.1 Gen 2 port is capable of providing 0.9A
to connected peripherals. The hub uses smart power technology to
determine where the most power is required and divert it automatically.
The hub receives up to 90W from the power adapter, with 10W allocated
as a buffer.
Note: the hub does not support PD Charging on any of the three
Thunderbolt 4 ports.
