Modular Thunderbolt 4 Dock with Swappable Design

This Thunderbolt 4 dock uses a modular design with a swappable connectivity module for easy field upgrades. IT teams can replace the power cable or connectivity module independently, each carrying its own service tag for targeted firmware deployment. Firmware updates complete in five to seven minutes without a system reboot, managed through Dell Client Command Suite or Microsoft System Center Configuration Manager. The single-cable connection simplifies desk setup for compatible laptops.

Simple Single-Cable Setup and Management

Installation requires only one cable between the dock and the host system to deliver power, data, and video. The 180W power adapter operates on 120 or 230 V AC at 50 or 60 Hz. Firmware updates take five to seven minutes without requiring a reboot, streamlining maintenance. Secure manageability features include MAC Address pass-through and remote port disablement, alongside PXE Boot and Wake-on-LAN support for IT control.

Thunderbolt 4 Bandwidth and Display Limits

The Thunderbolt 4 interface provides 40 GB/s data transfer bandwidth for connected peripherals. Video outputs include two DisplayPort 1.4 ports, one HDMI 2.0 port, and one USB-C Multifunction DisplayPort, supporting multiple 4K displays. Power delivery reaches 130W on Dell devices with ExpressCharge, achieving 80 percent charge in one hour or 35 percent in 20 minutes. Systems without Thunderbolt 4 or sufficient power-negotiation capability will not reach full charging speed or port throughput.
