The APC AP7900 is a professional switched and metered Power Distribution Unit (PDU) designed to provide reliable, managed power distribution for network and server equipment in data centers, server rooms, and equipment racks. Its primary function is to distribute AC power from a single source (like a wall outlet or UPS) to multiple devices via multiple outlets, while offering advanced control and monitoring capabilities. Unlike basic power strips, this PDU features individual outlet switching, allowing administrators to remotely power cycle specific pieces of equipment (e.g., a locked-up server or router) via a network interface without needing physical access to the data center. It also provides real-time power metering, reporting total current draw and helping to prevent circuit overloads.

Engineered for integration into intelligent infrastructure, the AP7900 includes a built-in network interface (typically 10/100 Ethernet) for out-of-band management. This allows IT staff to monitor power consumption, set alarm thresholds for current, and control outlet states through a web browser, SNMP, or Telnet/SSH. The unit is housed in a robust, vertical or horizontal, zero-U rack-mountable design, saving valuable rack space. It offers a range of outlet types (often IEC C13) to accommodate various server and network device power cords. Its robust construction and management features make it a critical component for maintaining uptime, optimizing power capacity, and enabling remote management in modern, highly available computing environments.

As a key element of data center infrastructure management (DCIM), the APC AP7900 provides both power distribution and intelligent control. It is used by organizations to improve operational efficiency, enhance remote troubleshooting capabilities, and gather data for capacity planning. By delivering reliable power with advanced monitoring and switching, it helps ensure the stability and manageability of critical IT assets.
