Vertiv SCM145DPH-400 Secure Desktop KVM Switch
Overview
The Vertiv SCM145DPH-400 is a 4-port secure desktop KVM switch built for environments where hardware-level isolation between computer sources is non-negotiable — think classified workstations, air-gapped networks, government ops centers, and financial trading floors where one operator must switch between systems that absolutely cannot share data paths. It supports 4K Ultra HD resolution at 60 Hz across HDMI and dual DisplayPort outputs, pairing high-fidelity video with a hardened USB switching architecture that prevents peripheral-borne data leakage between connected computers. For a broader look at the Vertiv secure KVM line, explore the Vertiv catalog.
SCM145DPH-400 (often searched as SCM145DPH 400) ships in a compact black desktop form factor. The console side presents two DisplayPort outputs, one HDMI output, three USB 2.0 Type-A hub ports, and a 3.5mm headphone jack — covering the full peripheral stack a modern analyst workstation requires without external hubs or adapters.
Key Features
- 4K Ultra HD at 60 Hz: Maximum resolution of 3840 × 2160 at 60 Hz means you get full-frame, pixel-accurate output at the native resolution of modern 4K monitors — no scaling artifacts or dropped frames during fast desktop switching. If your analysts run dual 4K displays, the two console DisplayPort outputs handle that without a second KVM in the chain.
- Dual DisplayPort + HDMI Console Outputs: Three video outputs on the console side (two DisplayPort, one HDMI) give you flexible monitor pairing — connect a primary 4K DP display and a secondary HDMI panel, or run two DP monitors simultaneously. Most secure KVMs in this class force you to choose one interface; this one doesn't.
- USB 2.0 Keyboard and Mouse Ports (Type-B per computer): Each computer connects via USB 2.0 Type-B, keeping the HID path isolated at the hardware level. Unidirectional data paths in secure KVM designs mean keystrokes and mouse events route to the active port only — no cross-contamination through shared USB arbitration logic.
- 3x USB 2.0 Type-A Hub Ports: Three downstream hub ports on the console let you connect a CAC reader, USB token, or additional peripherals without a separate hub. In a defense or finance context, this eliminates the temptation to plug shared USB devices directly into a computer port, keeping the security boundary intact.
- 3.5mm Headphone Output: Single analog audio output on the console side handles headset monitoring without requiring a separate audio switch. For environments where voice calls or audio alerts are part of the workflow, this removes one more piece of external gear from the desk.
- Wide Input Voltage Range (100–240 V AC): AC-powered with a 100–240 V input range — deploys on US, European, or international power infrastructure without a step-down transformer. Useful for government agencies and multinational organizations standardizing on one SKU globally.
- 0–40 °C Operating Range: Rated for 0 to 40 °C operating temperature and 0–80% relative humidity (non-condensing). Standard office and data center ambient ranges are covered; this is not rated for harsh industrial environments, which is appropriate for the secure desktop use case.
- Multi-Certification Compliance (FCC Class A, CE, TUV US, TUV Canada, RCM, VCCI): Carries FCC Class A, CE, TUV US, TUV Canada, RCM, and VCCI marks — covers North American, European, Australian, and Japanese regulatory environments. Procurement teams dealing with multi-region deployments can qualify a single part number rather than managing region-specific SKUs.
Integration and Compatibility
The SCM145DPH-400 takes USB keyboard and mouse input from the operator console and routes it to the active computer via USB 2.0 Type-B connections on each computer port. Video signals from connected computers arrive over the host-side video interfaces — review the Vertiv product documentation for specific per-port video connector types on the computer side, as the console outputs (HDMI, dual DisplayPort) are the operator-facing connections confirmed in evidence.
The USB 2.0 Type-A hub ports support peripheral sharing under the active session. For KVM switches in secure environments, verify that any connected peripherals (CAC readers, smartcard tokens) are on your site's approved peripheral list — secure KVMs with hardware isolation can still present a policy risk if unapproved USB devices are plugged into the hub ports.
Power is supplied via AC adapter; no PoE or DC input option is listed. Ensure a protected AC outlet is available at the operator console location. For larger multi-user deployments, see server management and console infrastructure solutions that may complement this switch.
Frequently Asked Questions
Q: What video interfaces does the SCM145DPH-400 support on the console (operator) side?
A: The console side provides two DisplayPort outputs and one HDMI output, supporting up to 4K Ultra HD (3840 × 2160) at 60 Hz. This allows connection of up to two DisplayPort monitors and one HDMI monitor at the operator desk.
Q: How many computers can the SCM145DPH-400 switch between?
A: The SCM145DPH-400 is a 4-port KVM, supporting connections to four separate computers or sources simultaneously, with the operator switching between them at the console.
Q: What certifications does the SCM145DPH-400 carry?
A: The unit holds FCC Class A, CE, TUV US, TUV Canada, RCM, and VCCI certifications, covering North American, European, Australian, and Japanese regulatory requirements.
Q: Does the SCM145DPH-400 require an external power supply?
A: Yes, it is AC-powered with an input voltage range of 100–240 V, making it compatible with standard power infrastructure worldwide. It does not support PoE or DC input.
Q: What peripheral ports are available at the operator console?
A: The console provides three USB 2.0 Type-A hub ports for peripherals (such as a CAC reader or USB token), plus a 3.5mm headphone output for audio. Keyboard and mouse connect via USB.
Q: What is the maximum operating temperature for the SCM145DPH-400?
A: The unit is rated for 0–40 °C operating temperature and 0–80% relative humidity, suitable for standard office and data center environments.
The SCM145DPH-400 is the switch I'd specify when a customer needs hardware-enforced isolation between classified and unclassified networks on a single desk without compromising on display fidelity. The combination of dual DisplayPort plus HDMI console outputs at 4K/60 Hz is genuinely rare in the secure KVM segment — most units in this class cap out at a single 4K output or drop to 30 Hz at full resolution, which is noticeable on modern high-refresh monitors.
Technical Highlights:
- 4K UHD at 60 Hz: 3840 × 2160 at 60 Hz is the threshold that separates a sharp, responsive analyst display from one that feels sluggish during fast scrolling or video playback. This matters most on large-format 4K panels common in intelligence and trading environments.
- Three Console Video Outputs (2x DP + 1x HDMI): Running a dual-monitor setup from a secure KVM without a downstream splitter eliminates a potential signal-path vulnerability. Both DisplayPort outputs can drive independent 4K sources — that's a meaningful architectural simplification.
- Six Certifications (FCC Class A, CE, TUV US/Canada, RCM, VCCI): Multi-region compliance on a single SKU matters for agencies procuring globally. TUV US and TUV Canada marks specifically address safety, not just EMC — relevant for facilities with strict equipment approval processes.
Deployment Considerations:
- The unit is AC-powered (100–240 V) — confirm a protected outlet is available at the console position. In dense operator workstation builds, power strip or UPS outlet allocation needs to account for the KVM as a separate load.
- Operating humidity is rated to 80% non-condensing. Standard office environments are fine, but avoid deployments in facilities without climate control — the 0–40 °C range also rules out uncontrolled industrial or vehicle-mounted scenarios.
The SCM145DPH-400 is the right fit for a 4-seat government analyst station or financial compliance desk where operators need seamless switching between isolated networks on high-resolution dual-display setups — and where the compliance paperwork requires documented regulatory certifications across multiple jurisdictions.
