Reduce console clutter and keep legacy PS/2 infrastructure manageable from one rack-mounted access point. The Black Box ServSwitch EC KV9004A gives administrators control of up to 4 computers through a compact 1U chassis, making it a practical fit for server rooms where every inch of rack space counts. Built for environments that still depend on PS/2 connectivity, this KVM switch supports a maximum video resolution of 1,920 x 1,440, preserving usable detail for BIOS-level work, diagnostics, and routine administration. Its rack-mountable design helps standardize access without adding bulk, while the included brackets, foot pads, power supply, and user manual simplify deployment. For teams maintaining mixed or older server estates, this model offers a focused way to centralize control without moving to a larger or more complex platform. It is a straightforward choice when you need dependable local switching, compact hardware, and a form factor that fits neatly into established infrastructure.
