KVM switch Belkin F1DN208KVM-UN-4 — 8-port dual-head HDMI/DisplayPort, USB keyboard & mouse, 4K@60Hz, rack-mount, black

Belkin F1DN208KVM-UN-4 is an 8-port rack-mount secure KVM switch that controls up to eight computers with dual-head video connections. The unit supports HDMI and DisplayPort inputs via combo connectors and provides USB keyboard and mouse connectivity. Designed for secure IT environments, it delivers up to 4K UHD (3840×2160) at 60 Hz per display, uses 12 V DC power with 100–240 V AC input, and is housed in a black steel chassis suitable for server rooms, control stations, and multi-computer secure setups.

Advantages

The KVM switch meets Common Criteria and NIAP Protection Profile for Peripheral Switching Devices v4.0 requirements and incorporates optical data diodes and peripheral emulation to maintain air-gap isolation while allowing safe peripheral sharing. Combo video connectors with internal conversion provide compatibility with modern and legacy video outputs without external adapters. The device includes an advanced ultrasonic audio filter and active anti-tamper protections, and it is manufactured in the US and TAA-compliant for use in regulated environments.

Suitable for

• Secure government, military, or healthcare IT environments requiring strict enclave separation
• Server rooms and control stations managing multiple computers from a single workstation
• Deployments needing both DisplayPort and HDMI compatibility and 4K@60Hz video performance

When it may not be suitable

This KVM switch is focused on security and compatibility rather than consumer features; it may be more complex than needed for simple home or small-office setups that do not require enclave isolation or TAA compliance. Additionally, environments that require non-standard peripheral types or proprietary video interfaces may still need specific adapters despite the combo connectors.

Key specifications

• Ports: 8 computer channels, dual-head video per channel (combo DisplayPort/HDMI)
• Video support: up to 4K UHD (3840×2160) at 60 Hz per display
• Peripheral interfaces: USB keyboard and USB mouse support
• Security features: optical data diodes, peripheral emulation, active anti-tamper, ultrasonic audio filtering (8th order elliptical)
• Power: 12 V DC input (supports 100–240 V AC via adapter)
• Form factor and finish: rack-mountable steel housing, black

How to use

Install the unit in a rack or place it on a stable surface, connect each computer to the switch using the appropriate Belkin cables (matching DisplayPort or HDMI outputs to the combo connectors), and attach the USB keyboard and mouse to the console ports. Power the device using the supplied adapter, then select channels using the front-panel controls or an optional Belkin Secure KVM remote control with integrated keyboard. The switch automatically handles video signal conversion and peripheral emulation to preserve secure isolation between connected systems.

What to consider before purchase

• Ensure connected systems use DisplayPort, HDMI, or compatible DVI outputs and that the proper Belkin cables are available
• Confirm that 4K@60Hz support is required for your monitors and workflows
• Verify that TAA compliance and the specified security certifications meet your organisation's procurement rules
• Assess whether rack-mount form factor and physical dimensions fit your installation

Usage recommendations

For secure multi-enclave operations, pair the KVM switch with Belkin’s Secure KVM Remote Control with Integrated Keyboard and use Belkin-approved cables to maintain compatibility and minimize operator errors while preserving strict isolation between systems.
