Plugable TBT4-UDX1 docking station

Most unexpected behavior with the TBT4-UDX1 can be resolved by verifying your host cable and power connections. Checking these physical connections ensures the dock is properly set up to communicate with your computer.

Instructions

Connect the dock to your computer using only the 1.0-meter long 40Gbps Thunderbolt 4 cable that Plugable originally included in the box (this cable features a small white flag listing the product model name and specifications).

Plug the Thunderbolt 4 cable into the single Thunderbolt 4 host connection port located on the front of the TBT4-UDX1 unit.

Plug the included power adapter securely into the dock’s power input port.

Connect the power cable securely into the power adapter.

Plug the power cable securely into a known-working electrical power outlet.

Press the power button located on the front of the unit to manually power on the dock if it does not turn on automatically.

Push the Thunderbolt 4 cable securely into a Thunderbolt 4 port on the host computer if the dock is powered on but not being detected.

Expected Result

When the TBT4-UDX1 is connected to a known-working electrical power outlet and powered on, there will be a solid green power indicator light present on the front of the unit. When successfully connected to a compatible host computer, there will be a solid blue host connection light present on the front of the unit.
