Manufactured by APC by Schneider Electric, this 2U rack-mountable PDU offers advanced load monitoring, remote outlet control, and network management capabilities, making it an essential tool for optimizing power distribution and minimizing downtime. In this blog, we’ll explore the specifications, features, performance, and value of the AP7922B to help you determine if it’s the right solution for your infrastructure.

Overview

The AP7922B is a switched rack PDU that combines metered power distribution with individual outlet control, allowing IT administrators to remotely manage power to connected devices. With 16 IEC-320 C13 outlets, a 32A, 230V input via an IEC-309 connector, and a 2U form factor, it’s designed for high-density server racks and network cabinets. Its advanced features, such as power sequencing, load monitoring, and network integration, make it ideal for critical IT applications requiring precise power management.

Key Features

1. 16 IEC-320 C13 Outlets

The AP7922B provides 16 IEC-320 C13 outlets, suitable for powering a wide range of IT equipment, including servers, networking devices, and storage systems. The C13 outlets are compatible with standard C14 power cords, offering flexibility for connecting various devices in a rack. The outlets support individual remote control, allowing administrators to turn them on or off to manage power usage or reboot locked-up equipment.

2. 32A, 230V Input with IEC-309 Connector

The PDU features a single IEC-309 32A input with a 3-meter (9.84-foot) cord, delivering a maximum power capacity of 7,360 VA (230V x 32A). This high-capacity input supports demanding IT environments, ensuring reliable power distribution to multiple devices. The PDU is single-phase, compatible with standard 230V, 50/60 Hz power systems, making it suitable for use in the UK, Australia, and other regions with similar power standards.

3. Switched Outlet Control

The remote individual outlet control feature allows administrators to turn outlets on or off via a web interface, SNMP, or Telnet. This capability is invaluable for:

• Power Cycling: Remotely reboot locked-up servers or networking equipment, reducing downtime and eliminating the need for on-site visits.
• Power Management: Turn off unused outlets to prevent overloads and optimize energy efficiency.
• Maintenance: Isolate specific devices for upgrades or troubleshooting without affecting others.

4. Power Delays for Sequencing

The AP7922B supports power delays, enabling users to configure the sequence in which outlets are powered on or off. This feature prevents in-rush currents during startup, which can overload circuits and cause tripped breakers. It also ensures that dependent equipment (e.g., servers relying on network switches) is powered on in the correct order, enhancing system reliability.

5. Local Current Monitoring and Digital Display

A built-in digital display shows the aggregate current draw per phase, helping installers avoid overloaded circuits. The load indicator LED provides visual warnings when the current draw approaches user-defined alarm thresholds, ensuring proactive management of power loads. This feature is critical for maintaining safe operating conditions in high-density racks.

6. Network Management Capabilities

The AP7922B offers full-featured network management via:

• Web Interface: For easy access and configuration from any browser.
• SNMP: For integration with network management systems.
• Telnet/SSH: For secure command-line access.
  These interfaces allow remote monitoring, configuration, and firmware upgrades, saving time and reducing the need for physical access. The PDU integrates with StruxureWare Data Center Expert, providing a unified view of data center infrastructure with critical alerts and surveillance capabilities.

7. Flash Upgradeable Firmware

The PDU supports flash-upgradeable firmware, allowing users to download updates via the network to add new features or improve performance. This ensures the AP7922B remains relevant as technology evolves, eliminating the need for hardware replacements.

8. Alarm Thresholds

Users can define alarm thresholds for current draw, triggering network and visual alerts (via the load indicator LED) to prevent overloads. This proactive monitoring helps maintain system stability and prevents costly outages.

9. 2U Rack-Mountable Design

The AP7922B’s 2U horizontal form factor is designed for standard 19-inch server racks and cabinets. Measuring 444 x 112 x 89 mm (17.5 x 4.4 x 3.5 inches) and weighing approximately 4.55 kg (10 lbs), it optimizes rack space while providing robust power distribution. The PDU includes rack-mounting brackets for secure installation.

10. Safety and Compliance

The AP7922B is certified to meet stringent safety standards, including CE, EN 55022 Class A, EN 55024, EN 61000-3-2, EN 61000-3-3, GOST, VDE, and REACH. It is RoHS-compliant, ensuring environmental responsibility. The PDU operates reliably in temperatures from 0°C to 45°C (32°F to 113°F) and 5-95% non-condensing humidity, suitable for most data center environments.

11. 2-Year Warranty

The AP7922B comes with a 2-year repair or replace warranty, providing peace of mind. Some retailers, like IP Trading in Australia, offer extended warranty options with benefits like 24/7 technical support and free shipping on replacement parts.

Performance

The AP7922B delivers reliable power distribution with a maximum input current of 32A and a power capacity of 7,360 VA, sufficient for high-density IT environments. Its switched outlet control enables precise power management, with users reporting seamless remote reboots and power cycling for servers and networking devices. The digital display and load indicator LED provide real-time feedback, with the PDU accurately reporting current draw to prevent overloads. In testing, the PDU maintains stable performance under heavy loads, and its 1ns response time to surges ensures robust protection for connected equipment.

The network management capabilities are highly praised, with the web interface being intuitive for configuring outlet schedules, monitoring power usage, and setting alerts. Integration with StruxureWare Data Center Expert enhances scalability for large data centers. Users note that firmware upgrades are straightforward, ensuring the PDU remains up-to-date.
