A cabinet in a series located at the end of each hot/cold aisle in data halls and connected to racks via cables and trays above future rack locations.

• A. Power Distribution Cabinet (PDC)
• B. Panel Distribution Cabinet (PDC)
• C. Data Cable Cabinet (DCC)
• D. Cable Management Cabinet (CMC)

Answer: (A)

Power Distribution Cabinets are placed at the end of each hot and cold data hall aisle to feed electrical power to the racks that will occupy the row. They serve as the central source of power for the equipment, with cables running from the cabinet to each rack location and overhead trays guiding those cables as future racks are added. This setup emphasizes supplying electricity to racks rather than handling data cables or general cable organization. Data Cable Cabinets focus on routing data cables, while Cable Management Cabinets are for organizing and routing cables (often both power and data but not primarily for distributing rack power). A Panel Distribution Cabinet is a broader term and doesn’t specifically describe the end-of-aisle power feed to racks. So the described cabinet is a Power Distribution Cabinet.
