In the fast-paced world of IT infrastructure, maintaining a reliable and efficient power supply is critical. Whether you’re managing a small server room or a sprawling data center, power distribution units (PDUs) play a vital role in keeping your equipment operational and protected. One standout option in this category is the APC Rack PDU, Switched, 2U, 32A, 230V, (16)C13 (AP7922B), designed by APC, a globally recognized leader in power management solutions under Schneider Electric. This blog dives into what makes the AP7922B an excellent choice for modern power distribution needs, its key features, and why it’s a smart investment for businesses and IT professionals.
What is the APC AP7922B Rack PDU?
The APC AP7922B is a switched rack power distribution unit (PDU) designed to deliver advanced power management and remote control for connected devices. Unlike basic power strips, this PDU offers individual outlet switching, load monitoring, and network connectivity, making it ideal for environments where uptime and efficiency are non-negotiable. It’s a 2U (two rack unit) device, meaning it occupies two slots in a standard 19-inch server rack, and it’s built to handle 32A at 230V, providing a robust 7,360VA load capacity. With 16 IEC C13 outlets, it’s equipped to power a variety of rack-mounted equipment, from servers and networking gear to storage devices.
This PDU is tailored for the UK and other regions using 230V power, featuring an IEC 309 32A input plug with a 10-foot cord for flexible installation. It’s more than just a power strip—it’s a smart solution for optimizing power usage and ensuring operational continuity.
Key Features of the AP7922B
- Switched Outlets for Remote Control
The AP7922B’s standout feature is its ability to remotely turn individual outlets on or off via a network interface. This is a game-changer for IT administrators, allowing them to reboot locked-up equipment, power-cycle devices, or shut off unused outlets to prevent overloads—all without physically being on-site. - 16 IEC C13 Outlets
With 16 outlets, this PDU can support multiple devices in a single rack. The IEC C13 connectors are widely used in IT equipment, offering compatibility with servers, switches, and other critical hardware. - 32A, 230V Power Capacity
Rated for 32 amps at 230 volts, the AP7922B delivers up to 7,360 volt-amps (VA) of power, making it suitable for high-density racks. It’s designed to handle demanding loads while maintaining stability. - Network Management Capabilities
The PDU features full-featured network management through Web, SNMP, and Telnet interfaces. This allows users to monitor power usage, configure settings, and receive alerts from anywhere, saving time and reducing the need for physical intervention. Firmware upgrades can also be applied remotely via network downloads, ensuring the unit stays up-to-date with the latest enhancements. - Power Sequencing and Delays
To prevent inrush currents that could trip breakers during startup, the AP7922B lets you configure the sequence and timing of outlet activation. This is especially useful for powering on equipment in a specific order, ensuring dependent devices function correctly. - Local Current Monitoring Display
A built-in digital display shows the aggregate current draw per PDU, helping installers and admins avoid overloading circuits. Paired with a load indicator LED, it provides visual warnings when the current approaches user-defined thresholds. - Alarm Thresholds
You can set custom alarm thresholds to receive network and visual alerts if power levels approach unsafe limits. This proactive feature helps prevent outages and equipment damage. - Compact 2U Design
Measuring just 2U in height, the AP7922B fits horizontally into standard racks without taking up excessive space. It ships with rack-mounting brackets for easy installation.
Why You Need a Switched Rack PDU Like the AP7922B
Traditional power strips offer basic connectivity, but they lack the intelligence and control needed for modern IT environments. The AP7922B addresses several critical needs:
- Remote Management: Restarting a server or troubleshooting equipment from afar saves time and travel costs, especially in distributed or unmanned facilities.
- Power Optimization: Turning off unused outlets reduces energy waste and prevents circuit overloads.
- Uptime Assurance: Sequencing and monitoring features minimize downtime by ensuring stable power delivery and quick recovery from issues.
Power disruptions—whether from grid fluctuations, equipment faults, or human error—can lead to data loss, hardware failure, or costly outages. The AP7922B mitigates these risks with its advanced capabilities, making it a must-have for data centers, server rooms, and enterprise IT setups.
How to Use the AP7922B
Setting up the AP7922B is straightforward:
- Mount the PDU in your 2U rack space using the included brackets.
- Connect the IEC 309 32A plug to a compatible 230V power source.
- Plug your devices into the 16 C13 outlets.
- Configure the network settings via the Web interface, SNMP, or Telnet to enable remote monitoring and control.
- Set power sequencing and alarm thresholds to match your operational needs.
The 10-foot cord provides flexibility in positioning, and the local display and LEDs give instant feedback on power status.
Who Should Use the AP7922B?
This PDU is perfect for:
- Data Center Managers: Manage high-density racks with precision and reliability.
- IT Administrators: Remotely troubleshoot and optimize power for servers and networking gear.
- Small to Medium Businesses: Protect critical equipment in a cost-effective, scalable way.
Its robust design and advanced features also make it suitable for edge computing sites, telecom setups, and any environment requiring dependable power distribution.
