Frequently Asked Questions

Dell Pro Thunderbolt 4 Smart Dock SD25TB4 (210-BRKN)
Frequently Asked Questions (FAQ's)

What laptops is the SD25TB4 compatible with?

The dock supports any laptop with a USB‑C or Thunderbolt 4 port that also supports DisplayPort Alt Mode and USB Power Delivery. For full performance — especially the 130W charging and full manageability features — it works best with compatible Dell commercial laptops (e.g., Latitude, Precision, XPS). Non‑Dell laptops will see up to 96W of power delivery.

How many external displays can I connect and what resolutions are supported?

You can support: Up to 4× 4K (3840×2160) @ 60Hz, up to 2× 6K (6144×3456) @ 60Hz, and up to 1× 8K (7680×4320) @ 60Hz (with DSC).

Does it support Mac or non‑Windows systems?

Yes, macOS, ChromeOS, Ubuntu and Red Hat Enterprise Linux are listed as supported OSes. However, some advanced features like PXE Boot, MAC passthrough or Intel vPro out‑of‑band management may only be fully supported on Windows / select Intel systems.

What kind of power adapter and cable does it use?

The dock comes with an integrated cable (USB‑C/Thunderbolt) upstream to the laptop and includes a power adapter rated for up to 180W to support full power delivery and connected peripherals.

Can I use the USB‑A ports to charge my phone or other devices when the laptop is disconnected?

Yes, the dock supports “PowerShare” on the USB‑A and USB‑C ports, meaning you can charge devices even when the laptop is not connected or is powered off.

What network performance does the dock provide?

It has an RJ‑45 port supporting 2.5 Gb Ethernet (2.5 GbE) for fast wired networking, useful for large file transfers, streaming and corporate LAN environments.

Is the dock manageable by IT departments?

Yes. It supports remote firmware upgrades (no PC required), remote port disablement, wake‑on‑LAN, MAC pass‑through, PXE Boot and other enterprise deploy features via the Dell Device Management Console.

Does it reduce cable clutter?

Yes — by consolidating power, video, data, and network into one upstream cable plus peripherals connected to the dock, it dramatically cuts down on adapter tangle and makes docking/undocking simple.

What are the physical dimensions and design features?

The approximate size is 20.5 cm (height) × 9 cm (width) × 3.52 cm (depth), and weight around ~579 g. Cable direction can be routed left or right to fit your desk setup.

How secure is this dock for enterprise use?

The dock includes tamper‑resistant hardware encryption, WPA‑3 192‑bit WiFi encryption (for managed WiFi docking) and Kernel DMA protection. These features make it suitable for environments where security is essential.

Will the full 130W power delivery work with my non‑Dell laptop?

No — although the dock can deliver 130W for Dell systems, non‑Dell systems are limited to 96W of power delivery. Still plenty for many modern laptops, but check your laptop’s USB‑C PD specification.

Can I mount the dock under a desk or behind a monitor?

While the specification sheet does not list a dedicated mounting kit for this dock, its compact form factor and ambidextrous cable routing make it very desk‑friendly. For under‑desk mounting you may need a third‑party bracket.

Are firmware updates required?

Not mandatory for basic use — but for full enterprise features (remote management, security protections) keeping firmware up to date is recommended. The dock supports firmware update even when the laptop is disconnected.

Is this dock future‑proof for next‑gen devices?

Yes — with Thunderbolt 4, dual 40Gbps channels, 2.5 GbE, 4K & 8K display support and single‑cable docking, this dock is well positioned to serve as a workstation hub for the coming years.

Does the dock support daisy-chaining via Thunderbolt 4?

Yes, the SD25TB4 supports Thunderbolt 4 daisy-chaining, allowing you to connect additional Thunderbolt peripherals such as external storage drives, additional displays (within GPU limits) or other docks in series—without sacrificing performance or stability. This is especially useful in creative and data-intensive environments that require expanded I/O and display capabilities.
