P085 / Thunderbolt / Guide

Choose the host port on a dock

Name the upstream host link before counting the other sockets.

The useful distinction

Use the exact model, port label and documentation section; this is a planning method rather than an automatic identification.

The useful distinction

Understand the requirement.

CalDigit describes one TS4 Thunderbolt port for the host connection and two for downstream devices. [C085A]

A manufacturer URL is a research pointer, not a verified assertion that every requirement has been met. The planner does not fetch that page or approve a declaration because the URL looks official.

Before you connect

What to check

  1. Identify the exact dock model.
  2. Use its host-port label, not a convenient socket of the same shape.
  3. Record the host cable as a separate component when needed.
  4. Keep every display and peripheral requirement tied to the host documentation.

Capture the evidence package

Keep the exact host model, dock model, cable identification, operating system and desired outputs together. Omit sensitive serial numbers from portable files.
