Episode 16: Power Distribution Units — Rack-Level Power Configuration
This episode explains the role of power distribution units (PDUs) in delivering stable and organized electrical power to servers and other rack-mounted equipment. You’ll learn about basic PDUs, metered units, and intelligent PDUs that provide monitoring, remote control, and environmental sensing capabilities. The discussion includes how PDUs are rated for load capacity, the importance of proper grounding, and how redundancy is achieved through dual-feed configurations. We also cover the integration of PDUs into rack layouts to maintain accessibility while avoiding cable obstruction.
The second half explores practical considerations for selecting and deploying PDUs in both exam scenarios and production environments. Examples show how to size a PDU based on anticipated rack load, distribute outlets to minimize cord strain, and align PDU placement with cable management systems. We also address the consequences of improper configuration, such as overloaded circuits or inaccessible connections. By understanding these principles, candidates can design safe, efficient, and scalable rack power systems.
