Product information

Description

HP Flexible Slot Power Supplies deliver up to 94% efficiency with 80Plus Platinum-certified designs that reduce server power consumption and lower wasted energy in data centers. The Flex Slot form factor is 25% smaller than the previous Common Slot generation, freeing internal space for additional server options and supporting improved overall server performance.

Advantages

These power supplies offer high energy efficiency to decrease operational power costs while maintaining IT performance. The compact Flex Slot design increases internal space for add-on components. Tool-less hot-plug access enables rapid service and replacement without specialized tools. Broad compatibility across the ProLiant DL300 Gen9 Server family simplifies spare parts management and helps reduce total data center costs. The 1400W Platinum Plus option includes embedded power-line communication support for HP Power Discovery Services.

Key specifications

  • Efficiency: up to 94% (80Plus Platinum certified)
  • Form factor reduction: 25% smaller than previous generation Common Slot
  • Serviceability: tool-less hot-plug access
  • Compatibility: supported across ProLiant DL300 Gen9 Server family
  • Optional feature: 1400W Platinum Plus with embedded power-line communication for Power Discovery Services

How to use

Install the Flex Slot power supply into compatible ProLiant DL300 Gen9 server bays according to the server maintenance guide. Use the tool-less hot-plug mechanism to remove or replace power supplies while the server remains powered, following proper safety and ESD procedures. When deploying the 1400W Platinum Plus option, enable and configure HP Power Discovery Services per your datacenter monitoring setup to collect power usage and telemetric data.

Recommendations

Choose the Flex Slot model that matches your server power requirements and compatibility with ProLiant DL300 Gen9 systems. Consider the 1400W Platinum Plus option if you require embedded power-line communication for HP Power Discovery Services and centralized power monitoring.
