Black Box ServSwitch Secure KVM Switch with USB, EAL4+ Certified, DVI, 4-Port

In environments where security and reliability matter most, the Black Box ServSwitch Secure KVM Switch with USB, DVI, and 4 ports delivers trusted, hardware-based control of up to four computers from a single station. Built to meet rigorous security standards, this KVM switch provides robust data isolation, preventing cross-contamination between connected systems while delivering crisp, digital video and seamless peripheral sharing. Its EAL4+ certification signals a level of evaluation and assurance that makes it well-suited for government, finance, healthcare, and other restricted operations where sensitive information must stay compartmentalized. Whether you manage a small data center, a security-critical lab, or a control room, this 4-port switch simplifies complex multi-system workflows without compromising on security or performance.

• Robust data isolation and security architecture: The ServSwitch Secure KVM Switch is designed to enforce strict port-to-port electrical isolation, enabling clear data separation (RED/BLACK) between connected workstations. This hardware-based approach minimizes the risk of data leakage or crossover between systems, helping organizations maintain compliance with security policies and regulatory requirements.
• High-quality DVI video and USB peripheral support: Share a single monitor, keyboard, and mouse across up to four computers with dependable DVI video routing and USB peripheral connectivity. This combination ensures crisp, digital video fidelity and broad compatibility with modern peripherals, delivering a smooth user experience in high-demand environments.
• Channel-to-channel integrity with 60-dB isolation: Each channel is engineered to minimize crosstalk and signal interference, providing strong protection against eavesdropping or inadvertent data transfer between active channels. The result is confident, secure operation when monitoring multiple systems side by side.
• Permanently wired, security-focused design: Built for restricted environments, the ServSwitch Secure uses a permanently wired configuration that reduces tampering risk and eliminates removable cables from critical security paths. This design choice supports consistent security posture and stable performance in mission-critical deployments.
• Flexible access and control for IT teams: The 4-port configuration supports efficient multi-system management from a single workstation, with straightforward switching between connected computers. Front-panel buttons and keyboard-based switching options typically provide rapid access in busy operations, enabling operators to maintain workflow continuity without compromising security.

how to install [product]

• Plan your layout: Decide which four computers will connect to the ServSwitch and designate a dedicated console (keyboard, mouse, and monitor) for the shared setup. Label cables to simplify troubleshooting and future maintenance.
• Connect display: Attach the monitor to the DVI output on the ServSwitch using a high-quality DVI cable to ensure optimal video clarity and stability.
• Connect hosts: Run individual DVI video cables from each computer's display output to the corresponding DVI input on the ServSwitch. Connect each computer’s USB peripherals (keyboard, mouse, and any other USB devices) to the matching USB ports on the switch for complete peripheral sharing.
• Console connections: Plug your keyboard and mouse into the designated USB console ports on the ServSwitch. If an integrated USB hub is provided, connect the hub to the appropriate port and attach the console devices there.
• Power and test: Power on the ServSwitch as required by the model’s documentation. Verify that each connected computer appears on the console by switching channels via the front-panel buttons or the supported hotkey sequence. Confirm video integrity, peripheral responsiveness, and stable operation across all four hosts.

Frequently asked questions

• What is the ServSwitch Secure KVM Switch best used for? It is designed for secure environments that require controlled access to multiple computers from a single console while maintaining strong data separation and hardware-based protection against leakage between channels.
• Which devices are supported? The switch provides USB connectivity for keyboards and mice and uses a DVI video interface for display. Compatibility with a wide range of USB HID devices is typical, but for non-standard peripherals, verify compatibility with your model’s documentation.
• How many computers can be managed with this 4-port model? Up to four separate computers can be controlled from one shared console, enabling efficient workflows in space-constrained or security-focused settings.
• What does EAL4+ certification mean for my deployment? EAL4+ certification indicates that the product has undergone a formal security evaluation and adheres to a defined set of hardware and software security requirements, providing assurance for environments with strict security policies.
• Does the switch support hot-key switching or front-panel control? Yes. Typical configurations offer convenient front-panel switching as well as keyboard-based hotkey control to quickly switch the active host without leaving the desk.
• Are there any special installation considerations for secure deployments? In secure environments, ensure that the wiring adheres to your organization’s physical security guidelines and that the switch remains in a controlled area. Use approved cables and maintain consistent labeling to support audits and maintenance.
• Where can I find the official specifications? Technical specifications are typically available through the vendor’s listing or catalogs. If you need exact figures (supported resolutions, power requirements, or additional interface details), consult the product’s datasheet or the supplier’s online spec sheet.
