4-Port Dual-Head Secure KVM Switch

The Vertiv SC940DPH-400 is a NIAP Protection Profile 4.0 certified KVM switch designed for high-security desktop environments. It allows a single operator to control four isolated computers using dual DisplayPort monitors and shared USB peripherals. Government agencies and defence contractors use it to eliminate data leakage between classification levels.

Isolated Ports and Tamper-Evident Labels

Each of the four ports maintains discrete processing paths that prevent signal crosstalk and data transfer between connected systems. Holographic tamper-evident labels on the chassis provide immediate visual confirmation if the hardware has been physically compromised. Customizable front-panel indicators give operators instant situational awareness of the active channel.

Four-System Capacity with Dual-Display Support

The switch comfortably handles four separate workstations, each driving two DisplayPort monitors for multi-head workflows. It runs out when a fifth system must be added or when video interfaces other than DisplayPort are required. The 3.70 lb chassis measures 2.20 by 5.00 by 13.70 inches, fitting standard desktop deployments.

Questions about this item

Will the holographic tamper-evident labels on the SC940DPH-400 need periodic replacement?

The tamper-evident holographic labels are permanent security features designed to visibly indicate any physical compromise; they do not require scheduled replacement unless damaged or triggered.

What limits sustained operation of the 4-port dual-head switch first?

The SC940DPH-400 uses isolated ports with discrete processing paths per channel, so sustained use is constrained by the 400 model's four independent DisplayPort and USB pathways rather than a shared bus.

How much heat and power does the 3.70 lb unit produce when running all day?

The compact 2.20" x 5.00" x 13.70" chassis operates without active cooling fans, drawing minimal power to maintain NIAP 4.0 certified isolation across four ports during continuous operation.
