Frequently Asked Questions
What is the primary function of the HPE 720480-B21 Flex Slot Power Supply? +
The HPE 720480-B21 is a high-efficiency 800W power supply unit designed for data center environments utilizing -48VDC power architecture. It provides reliable, redundant power conversion for compatible HPE ProLiant servers, ensuring consistent operation and protecting your hardware against utility power fluctuations while maintaining optimal energy efficiency in standard server racks.
Is the 720480-B21 compatible with all HPE ProLiant Gen9 and Gen10 servers? +
This power supply is specifically engineered for use with HPE ProLiant Gen9 and Gen10 server series that support the Flex Slot form factor. We recommend checking your specific server’s QuickSpecs to confirm compatibility, as the Flex Slot design requires a specific bay interface to ensure proper physical seating and power delivery within the chassis.
Does the 720480-B21 support hot-plug functionality? +
Yes, this unit features hot-plug capabilities, allowing for maintenance or replacement without shutting down the server. When deployed in a redundant configuration, you can safely remove and replace a failed power supply while the server remains fully operational, which is critical for maintaining high availability in enterprise-grade server environments.
What is the specific input voltage range for this power supply? +
The 720480-B21 is designed specifically for -48VDC input environments. This makes it an ideal solution for telecommunications facilities or specialized data centers that run on DC power infrastructures. It converts the input power into the standardized output required by the server’s internal components while maintaining strict thermal and electrical specifications.
How does the Flex Slot design improve server power management? +
The Flex Slot design allows for a smaller, common form factor across multiple HPE server platforms. This standardization simplifies inventory management and deployment, as the same power supply unit can often be used across different server models within your environment, reducing the complexity of managing disparate spare parts for your network infrastructure.
Can I use the 720480-B21 in a redundant power configuration? +
Absolutely. This unit is intended for high-availability setups. By installing two 720480-B21 power supplies into a server supporting redundant power, you create a failover mechanism. If one power source or unit experiences a fault, the secondary supply immediately assumes the full load, preventing unexpected server downtime and ensuring continuity for critical business applications.
What are the thermal benefits of using this 800W Flex Slot module? +
These modules are built for high-efficiency performance, which directly correlates to lower heat dissipation within the server chassis. By operating with high power efficiency, the 720480-B21 reduces the cooling load on your server fans and data center HVAC systems, ultimately contributing to a more sustainable power profile and reducing overall operational cooling costs.
What should I look for when installing the 720480-B21 to ensure safety? +
When installing, ensure the power supply is fully seated and the locking latch is engaged to prevent accidental disconnection. Because this unit utilizes -48VDC, always follow standard DC power safety protocols, verify that your rack’s power distribution unit is properly configured for the correct voltage, and ensure that all electrical grounding requirements are met before powering the unit.
How can I obtain a bulk quote for multiple HPE 720480-B21 units? +
For organizations planning large-scale deployments or infrastructure upgrades, we offer competitive bulk pricing. Please contact our sales team directly through our website with the requested quantity and your delivery requirements.
