Vertiv Cybex SC840DVI-400 4-Port DVI KVM Switch

The Vertiv Cybex SC840DVI-400 is a secure desktop KVM switch designed for operators managing four DVI-connected computers from a single display and peripheral set. It suits environments where isolation between connected systems is a mandatory requirement. The unit provides single-display presentation across all four ports.

Capacity and headroom

Four DVI ports allow simultaneous secure access to four separate computers without signal leakage between channels. The 4.0 specification supports single-head operation per port, so dual-display workstations fall outside the intended scope. Buyers needing more than four ports or multi-monitor switching per system must select a different model.

Questions about this item

Will the SC840DVI-400 work with my older DVI monitors and legacy PS/2 keyboards?

The switch provides four DVI ports for single-display operation and supports standard USB or PS/2 console connections, so older DVI monitors and PS/2 keyboards can be used with the appropriate cables.

How can I confirm the SC840DVI-400 is switching correctly after I connect four computers?

Press the front-panel port buttons; the corresponding LED for each port lights up to show the active channel, and the video signal appears on the attached DVI display.
