Black Box SM962A 4U Gang Switch Controller

Keep switching operations under direct control with the Black Box SM962A 4U Gang Switch Controller. Built for the Pro Switching System Plus, this controller card gives infrastructure teams the ability to switch one card, an entire gang switch, or a full daisy-chained system through Ethernet. It also supports front-panel control for local operation, plus SNMP and RS-232 for integration into managed environments. The controller is required for each 18-slot chassis and occupies two card slots, making it a dedicated control component rather than a general-purpose accessory. That design matters in environments where port-level isolation, coordinated switching, and repeatable control paths are part of daily operations. For labs, test racks, and service environments, it provides the control layer needed to manage complex switching without adding unnecessary steps. When uptime, repeatability, and operator control matter, this controller helps keep the switching fabric predictable. It is a practical fit for teams that need centralized command over multiple ports and chassis while preserving access through the interfaces technicians already use.
