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.
