A header cabinet (or column head cabinet) is typically installed at the top or end of a row of server racks. It functions as a row-level electrical enclosure, receiving power from upstream distribution cabinets and redistributing it to individual rack PDUs. Header cabinets can be designed for strong current (high voltage) or weak current (low voltage) applications and are usually constructed from high-quality steel with front and rear doors, side panels, and top plates for ventilation and access .
Once installed, the header cabinet PSU feeds power to rack-level PDUs, which distribute electricity to servers, switches, and storage devices. Vertical PDUs are commonly mounted along the rear struts of the cabinet, providing organized and accessible power outlets. Using industrial connectors like CEE plugs ensures reliable high-current connections and prevents accidental disconnections . By following these steps, the power supply in a header cabinet can be installed safely, efficiently, and in a way that supports reliable operation of the entire row of server racks.
