APC APDU9959NA3 0U Switched Rack Power Distribution Unit
Overview
The APC APDU9959NA3 is a high-density switched rack power distribution unit engineered for remote outlet control and management in data center and enterprise rack environments. Infrastructure teams use this PDU where fine-grained outlet switching and sequencing improve operational efficiency, enable automated power cycling of hung devices, and support controlled startup sequences without physical access. The switched design enables individual outlet on/off control over network interfaces, helping isolate faulty devices or enforce orderly power-up orders during maintenance or recovery.
Configured for 208 V AC input with a maximum current of 20 A, the unit supports a substantial total load capacity suitable for rack-level circuits feeding high-density IT equipment. Power is distributed through 21 IEC 60320 C13/C15 and 3 IEC 60320 C19/C21 outlets, matching cable standards common in server, storage, and network infrastructure. This outlet mix accommodates both standard and higher-temperature rated power cords.
The APDU9959NA3's zero-U vertical form factor mounts alongside standard 19-inch rack posts or channels without consuming usable rack unit space, preserving space for active equipment while delivering broad power connectivity. Vertical mounting and a slim profile simplify cable routing and cooling airflow management in dense cabinet deployments.
Management capabilities include remote control and monitoring via Web, SNMP, Redfish, and CLI interfaces over Gigabit Ethernet connections, enabling integration into centralized monitoring systems and DCIM platforms for automated alerting, power event scripting, and outlet-level control. Hot-swappable network management modules minimize downtime when upgrades or maintenance are required.
This PDU does not provide battery backup or ride-through capability; it should be used with upstream UPS infrastructure where continuity through utility outages is required. It is not designed as a UPS replacement or for power conditioning.
