Secure 4-port KVM for DisplayPort workstations

The Vertiv SC840D-001 is a single-head KVM switch that lets one user control four computers through a single DisplayPort monitor, USB keyboard and mouse. It supports UHD 4K resolution up to 3840x2160 at 30 Hz and includes audio switching for a complete desktop experience. The unit is designed to meet NIAP Protection Profile V3.0 requirements for secure peripheral sharing.

Verify DisplayPort 1.2 sources

Each of the four computer ports requires a DisplayPort 1.2 output capable of 3840x2160 at 30 Hz, plus a USB Type-A connection for keyboard and mouse signals. The console side uses USB Type-A for peripherals and a single DisplayPort input for the monitor. Ensure your cables match these connectors and that your displays support the stated resolution and refresh rate.

Fanless 35 W design runs silently within 0–40 °C

The switch draws a maximum of 35 W from a 100–240 V AC supply and operates without fans, so it adds no audible noise to the workspace. Operating temperature range is 0 to 40 °C with humidity up to 80 % RH non-condensing. Isolated processing paths prevent data leakage between ports while maintaining stable video and USB performance under continuous use.
