Description

Vertiv SC840DPH-400 Secure Desktop KVM Switch

Overview

The Vertiv SC840DPH-400 is a secure desktop KVM (Keyboard, Video, Mouse) switch designed for environments demanding strict isolation between systems. It allows a single user to access multiple computers from one workstation, ensuring that data cannot leak between connected devices. This unit is ideal for secure government, military, or financial operations where air-gapped systems are mandatory. The SC840DPH-400 model provides 4-port connectivity for DPH (DisplayPort, USB, Power) interfaces.

Compatibility

This KVM switch is designed to work with computers and peripherals utilizing DisplayPort video connections and USB HID (Human Interface Device) for keyboard and mouse input. It supports secure operation with systems that require physical isolation, such as those found in classified environments. Specific compatibility is assured with systems adhering to the DPH interface standard for video, USB, and power. It is built for secure, dedicated workstations where system-to-system data transfer must be prevented.

Installation Notes

The Vertiv SC840DPH-400 requires standard DisplayPort cables for video and USB Type-A to Type-B cables for peripheral connectivity. Ensure that all connected computers are powered off before making connections to prevent potential hardware damage or data corruption. The unit draws power from the connected computers via USB, eliminating the need for an external power adapter. Its compact dimensions (5.0" W x 13.7" D x 1.7" H) allow it to fit easily on most desktop surfaces or within limited rack space.
