Control up to 16 servers from a single console and keep mixed legacy and USB environments organized. The Black Box KV9216A is designed for infrastructure teams that need one KVM switch to span PS/2 or USB servers and PS/2 or USB consoles without forcing a hardware refresh. That flexibility makes it a strong fit for racks where older systems and newer peripherals coexist. With 16 ports, this switch helps reduce the number of keyboards, mice, and monitors tied to the rack while keeping operator access direct and predictable. It is especially useful in environments where uptime, serviceability, and compatibility matter more than adding layers of remote management you may not need. For administrators, that means faster intervention, cleaner cabinets, and fewer points of failure at the console. Choose the KV9216A when you need a higher-density KVM built for practical deployment. It gives you the port count to scale within a cabinet and the interface flexibility to support mixed hardware without compromise.
