DELL 452-11421 laptop dock/port replicator Docking Black

The Dell E-Port Plus Replicator (Docking Station Dell 452-11421, MPN N1J67) expands a laptop into a desktop-like workspace by centralizing connections for power and peripherals. The black docking station provides AC power (130 W) and a compact footprint (288 mm × 170 mm × 53.7 mm). It is tested and validated with Dell systems and supported by Dell Technical Support when used with a compatible Dell laptop. The dock offers multiple video and USB ports plus an Ethernet connection for simplified, single-cable docking with supported Latitude models.

Advantages

The docking station replaces multiple cables by providing a single interface for keyboard, mouse, monitor, printer and other peripherals. It includes USB 3.0-capable ports for faster data transfer where platform support is available, adds DisplayPort 1.2 support for multi-monitor daisy-chaining when used with discrete graphics on current Latitude models, and maintains backward compatibility with earlier Latitude E-series without BIOS, software or hardware impact. The compact black design and 130 W AC power supply deliver reliable power and a tidy desktop configuration.

How to use

Place the docking station on a stable surface and connect the 130 W AC adapter to power the unit. Connect your laptop to the dock using the docking connector designed for supported Dell Latitude models. Attach peripherals such as keyboard, mouse, monitors (via DVI-D, VGA or DisplayPort), printer and Ethernet cable to the corresponding ports on the dock. If your laptop platform supports USB 3.0/3.2 Gen 1, the USB Type-A ports will operate at higher transfer speeds; otherwise they will function as USB 2.0.

Recommendations

Use the dock with the listed compatible Latitude systems to ensure validated functionality and Dell Technical Support coverage. For multi-monitor setups using DisplayPort 1.2 daisy-chaining, verify that the laptop has discrete graphics and that connected monitors support DP daisy-chain functionality. Keep firmware and drivers up to date on your Dell system for optimal compatibility.
