The Dell Pro Thunderbolt 4 Smart Dock SD25TB4 is built for business professionals, advanced workstation users, remote workers, and enterprise IT environments that require high-speed connectivity, reliable laptop charging, multi-monitor support, and remote dock management.
It connects a compatible laptop to displays, wired Ethernet, keyboards, mice, printers, external storage, and other USB accessories through a single Thunderbolt 4 cable. The dock delivers up to 130W of power to supported Dell systems and up to 96W to compatible non-Dell laptops. An 180W Dell AC power adapter is included.
For display connectivity, the SD25TB4 includes two DisplayPort 1.4 ports, one HDMI 2.1 port, one USB-C multi-function DisplayPort 1.4 port, and two Thunderbolt 4 ports. With compatible systems and Display Stream Compression, it can support up to four 4K displays at 60Hz, two 6K displays at 60Hz, or one 8K display at 60Hz. Actual display support depends on the connected laptop, graphics processor, operating system, monitor configuration, and cable type.
The dock includes four USB-A 3.2 Gen 2 ports and one USB-C 3.2 Gen 2 data port, providing speeds up to 10Gbps. Its two Thunderbolt 4 ports support high-speed accessories, external storage, and display expansion. A 2.5GbE RJ45 Ethernet port provides fast and stable wired networking.
The Smart Dock design supports remote firmware updates even without a connected PC, host-based updates, firmware updates when disconnected, and independent port disablement. It also supports enterprise features including MAC Address Pass-Through, PXE Boot, Wake-on-LAN, WLAN-to-LAN switching, Dock Power Button Sync, Kernel DMA Protection, and Intel AMT over Thunderbolt for selected Intel vPro systems. Dell provides a 3-year limited hardware warranty with Advanced Exchange service.
