Black Box ACXMODH4-PS Modular KVM Extender Chassis Redundant Power Supply

Overview

The Black Box ACXMODH4-PS is the factory-matched redundant power supply module for the Black Box Modular KVM Extender Chassis — purpose-built to eliminate a single point of failure in installations where KVM extension downtime is not an option. If you are running the KVM extender chassis in a broadcast control room, a 24/7 operations center, or a critical infrastructure environment, the ACXMODH4-PS (often searched as ACXMODH4 PS) is the component that keeps the chassis online when the primary supply fails. Black Box designs this module to slot directly into the ACXMODH4 chassis without tools, enabling hot-swap replacement without powering down the system.

Key Features

• Redundant Power Architecture: A second power supply in the chassis means a primary PSU failure does not take down your KVM extension links — critical in any environment where operators cannot leave their consoles.
• Chassis-Native Fit: Designed as a KVM accessory for the ACXMODH4 modular chassis, ensuring electrical and mechanical compatibility without adapters or third-party workarounds.
• Factory-New Genuine Module: Sourced factory-new — no refurbished or grey-market units — so the module meets the same tolerances as the chassis it protects.
• Supports Mission-Critical Uptime: Redundant power is a standard requirement in broadcast, government, and enterprise AV-over-IP deployments; the ACXMODH4-PS satisfies that requirement for the Black Box modular KVM platform.

Integration & Compatibility

The ACXMODH4-PS is designed for use with the Black Box ACXMODH4 Modular KVM Extender Chassis. Verify chassis compatibility with your existing KVM infrastructure before ordering. Consult pre-sales engineering if you are unsure whether your chassis revision accepts this power supply module — Black Box has revised the modular chassis across generations and slot compatibility should be confirmed against your chassis serial range.

Frequently Asked Questions

Q: What chassis is the ACXMODH4-PS compatible with?

A: The ACXMODH4-PS is the redundant power supply module for the Black Box ACXMODH4 Modular KVM Extender Chassis. Confirm your specific chassis revision with Black Box or pre-sales engineering before ordering to ensure slot and electrical compatibility.

Q: Can the ACXMODH4-PS be hot-swapped while the chassis is running?

A: The module is designed for the redundant power architecture of the ACXMODH4 chassis, which supports power supply replacement without full system shutdown. Confirm hot-swap capability for your specific chassis firmware revision with Black Box documentation before performing a live swap in a production environment.

Q: Is the ACXMODH4-PS sold as a standalone unit or as part of a bundle?

A: The ACXMODH4-PS is sold as a standalone redundant power supply module intended to be added to an existing ACXMODH4 chassis deployment.

Q: Does the ACXMODH4-PS come with a manufacturer warranty?

A: Black Box products carry a manufacturer warranty; the specific duration for the ACXMODH4-PS should be confirmed at time of purchase, as warranty terms vary by product line and region.

Marty Allison

The ACXMODH4-PS exists for one reason: to remove the power supply as a single point of failure in the Black Box ACXMODH4 modular KVM extender chassis. In my experience, integrators spec the chassis without the redundant PSU to hit a budget number, then face an unplanned outage when the primary supply fails mid-shift. The ACXMODH4-PS closes that gap without requiring a chassis replacement or system redesign.

Technical Highlights:

• Redundant Power Module: Adds a second power path to the ACXMODH4 chassis — if the primary PSU fails, the chassis continues operating without interruption, which is the defining requirement in control room and broadcast environments.
• Chassis-Native Design: Because this is a Black Box factory module for the ACXMODH4, you avoid the fit and compatibility risks that come with third-party PSU workarounds on modular chassis systems.
• Uptime-First Component: For any deployment where KVM extension downtime triggers an operational escalation — NOCs, dispatch centers, broadcast galleries — this module should be considered standard, not optional.

Deployment Considerations:

• Before ordering, confirm the ACXMODH4-PS is the correct power supply revision for your specific ACXMODH4 chassis serial range — Black Box has iterated the modular chassis and PSU compatibility is not always backward-universal.
• Do not assume hot-swap is available without verifying your chassis firmware version supports live PSU replacement — performing an unverified hot-swap in a live production environment carries risk.

The ACXMODH4-PS is the right call for any ACXMODH4 chassis deployment in a 24/7 operations environment — broadcast master control, government command centers, or enterprise NOCs — where a power supply failure cannot be allowed to cascade into a console outage.
