APC AP8961

Overview

The APC AP8961 is a switched rack power distribution unit designed to deliver 208-volt power efficiently within server racks while saving horizontal space by mounting vertically in the 0U channel. It features twenty-one C13 outlets and three C19 outlets, supporting a total load capacity of 5.7 kW, making it suitable for powering a variety of equipment such as servers, storage arrays, and network switches. This unit offers remote outlet control and real-time current monitoring, helping administrators manage power distribution and prevent overloads without needing physical access to the rack.

Key features

• Vertical 0U rack mount design that preserves valuable horizontal rack space for other equipment
• Remote outlet control via web browser, SNMP, or Telnet, allowing administrators to reboot devices or schedule power sequences remotely
• Real-time current metering displayed locally and over the network to monitor power usage accurately
• User-defined alarms that alert when power consumption approaches circuit limits, reducing the risk of breaker trips
• Support for an optional temperature or humidity sensor to extend environmental monitoring inside the rack
• Input plug with NEMA L21-20P configuration providing three-phase 208-volt power for high-density data center environments
• Integration with APC management software for unified monitoring alongside UPS systems and other infrastructure components

Connectivity and compatibility

This power distribution unit connects to three-phase 208-volt power sources using a NEMA L21-20P input plug, which is common in enterprise data centers and colocation facilities. Its mix of C13 and C19 outlets supports a wide range of rack-mounted equipment, including servers, switches, and storage devices. Remote management capabilities via web, SNMP, and Telnet protocols ensure compatibility with standard IT infrastructure monitoring tools.

Performance and reliability

The AP8961 offers precise current metering and user-configurable alarms to help prevent overloads that could disrupt operations. Its ability to remotely control individual outlets reduces downtime by enabling quick reboots of unresponsive devices without physical intervention. The option to add environmental sensors further enhances reliability by monitoring temperature and humidity conditions that affect equipment health.

Ideal uses and environments

This PDU is well suited for high-density data centers, enterprise server rooms, research laboratories, and colocation facilities where space efficiency and reliable power management are critical. IT teams benefit from its remote control and monitoring features, which simplify power management tasks and improve uptime. Its vertical mounting design makes it a strong choice for racks where horizontal space is at a premium.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
