This unit is engineered for versatility, supporting both PS/2 and USB connections via specialized P780-series cable kits. This hybrid compatibility ensures the switch can manage legacy hardware alongside modern systems without requiring additional adapters. For expanding infrastructures, the B042-004 features a dedicated daisy-chain port, allowing users to link up to 15 additional KVM switches to manage as many as 244 servers from a single station. The integrated On-Screen Display (OSD) provides an intuitive interface for naming and switching between connected ports, while the rugged steel housing ensures long-term durability in demanding data center conditions. Its rack-mount design and simple plug-and-play setup make it a reliable choice for streamlining local server access without the need for complex software installations.
