APC by Schneider Electric KVM-USB 3-Port USB KVM Switch
Overview
The APC by Schneider Electric KVM-USB is a compact, wired KVM switch that consolidates control of multiple systems through a single keyboard, video, and mouse setup. Designed for small server rooms, IT closets, and network management environments, the KVM-USB supports three port connections via D-Sub and USB on the host side and an RJ-45 connector for management access — giving administrators direct console control without requiring a dedicated monitor, keyboard, and mouse per machine.
Broad OS compatibility spans Windows, Linux, Unix, and Sun environments, which means mixed-platform racks — common in enterprise IT and light data center contexts — can be managed from a single console without swapping cables or deploying multiple KVM units. The 125 × 125 × 14 mm footprint keeps the switch from consuming meaningful rack or shelf space, and the 160 g weight reflects a unit built for fixed deployment rather than field portability.
For environments where physical console access matters — firmware updates, BIOS-level troubleshooting, OS recovery — a hardware KVM like the KVM-USB remains relevant even in largely remote-managed infrastructure.

Key Features
- 3-Port Wired KVM: Three discrete ports let you consolidate keyboard, video, and mouse control across three systems from one workstation — eliminating the per-machine peripheral overhead that clutters dense equipment spaces.
- D-Sub + USB Host Connectors: The D-Sub (VGA) video connector combined with USB HID input covers the widest installed base of servers and workstations in enterprise environments. No proprietary adapter required for standard rack servers.
- RJ-45 Connectivity: The RJ-45 port extends the switch's reach beyond direct-attached peripherals — useful for structured cabling environments where the KVM console is separated from the equipment being managed.
- Multi-OS Support (Windows, Linux, Unix, Sun): Mixed-OS racks are the norm rather than the exception in enterprise and government environments. Supporting all four major OS families from a single switch means you're not locked into a single-vendor stack.
- Compact Form Factor (125 × 125 × 14 mm, 160 g): At roughly the footprint of a CD case and 14 mm thin, the KVM-USB mounts or shelf-sits without consuming meaningful real estate. The 160 g weight means it won't stress lightweight cable management arms or thin shelves.
- Passive Wired Operation: No software agent, no network dependency, no cloud account — this is a purely hardware switch. That means it works during OS failures, network outages, and bare-metal provisioning cycles where software-based remote access is unavailable.
Integration & Compatibility
The KVM-USB is compatible with any system exposing standard VGA (D-Sub) video output and USB HID input — covering the majority of rack servers, workstations, and embedded systems shipped over the past two decades. The multi-OS support list (Windows, Sun, Unix, Linux) covers the dominant enterprise operating environments without requiring per-OS driver installation in most configurations.
Pairing with APC power protection infrastructure — UPS units, PDUs, and rack enclosures — creates a cohesive out-of-band management environment where physical console access and power control are both available locally. For broader network infrastructure deployments, the RJ-45 port supports structured cabling runs that keep the console workstation separate from the managed equipment. If you're evaluating KVM switch options across port counts and form factors, compare the KVM-USB against higher-port-count models in the APC line for larger deployments.
Frequently Asked Questions
Q: What operating systems does the KVM-USB support?
A: The KVM-USB supports Windows, Sun, Unix, and Linux operating environments, covering the most common enterprise and mixed-platform rack deployments.
Q: What connector types does the KVM-USB use?
A: The KVM-USB uses D-Sub (VGA) and USB connectors on the host/device side, and includes an RJ-45 port for extended connectivity.
Q: How many systems can I control with the KVM-USB?
A: The KVM-USB supports three ports, allowing you to manage up to three systems from a single keyboard, monitor, and mouse setup.
Q: Does the KVM-USB require special software or drivers to operate?
A: Based on available evidence, the KVM-USB operates as a wired hardware switch. Verify driver requirements for your specific OS configuration with the manufacturer before deployment.
Q: What are the physical dimensions of the KVM-USB?
A: The switch measures 125 mm wide × 125 mm deep × 14 mm high and weighs 160 g, making it suitable for shelf or surface mounting in space-constrained environments.
Q: Is the KVM-USB suitable for rack mounting?
A: The KVM-USB is a compact, low-profile unit (14 mm height) intended for shelf or surface placement rather than direct rack mounting. Verify rack mounting compatibility with APC accessories if a 1U rack installation is required.
The KVM-USB is the kind of hardware that earns its place in a rack not through feature breadth but through reliability in the moments software remote access fails — BIOS lockouts, network stack failures, mid-flash firmware hangs. At 125 × 125 × 14 mm and 160 g, it sits unobtrusively wherever you need a console tie-in without consuming a rack unit or requiring a dedicated power run.
Technical Highlights:
- 3-Port Wired Architecture: Three discrete managed connections let a single console operator work across three systems without any network dependency — critical for out-of-band recovery scenarios where the management VLAN itself may be down.
- D-Sub + USB Input: VGA plus USB HID covers essentially every rack server built in the last 20 years. No proprietary cable kit, no adapter cost — plug in and the switch is active.
- Multi-OS Host Support: Windows, Linux, Unix, and Sun on a single 3-port switch is a real operational benefit in mixed environments. You're not buying a second KVM for the Linux box or the legacy Sun workstation.
Deployment Considerations:
- The 14 mm unit height makes this a shelf or surface mount, not a direct 1U rack install. Plan for a 1U shelf or a flat surface adjacent to the rack if you need it co-located with managed equipment.
- Evidence does not confirm maximum cable run length on the RJ-45 port or whether an active extender is needed for runs beyond a few meters — verify with APC specifications before planning long console runs.
Best fit for a small server room or IT closet managing a mixed Windows/Linux environment where three systems share one physical console and out-of-band hardware access is the operational priority — the KVM-USB (often searched as KVM USB) handles that scenario cleanly without requiring any network infrastructure to function.
