Power supply HP Enterprise P21834-001 290W 1U Platinum

Hot-plug 290W power supply module in a 1U form factor with Platinum efficiency rating, compatible with selected HP Enterprise servers and chassis. This unit is designed as a redundant or replacement power source for rack-mounted systems in data center and enterprise environments. It delivers a stable 290W output while maintaining high energy-efficiency and controlled thermal characteristics to support continuous operation and minimize service interruptions.

Advantages

The power supply offers Platinum-level efficiency to reduce energy consumption and heat generation compared with lower-efficiency units. Its hot-plug capability allows replacement or insertion without shutting down the host server, supporting high availability. The compact 1U form factor enables deployment in dense rack configurations, and the module is engineered for stable voltage and current delivery under typical server loads.

Suitable for

• Redundant power configurations in enterprise racks
• Replacement of failed or aging power modules in compatible HP Enterprise servers
• Small to medium data center deployments requiring efficient continuous power
• Systems where hot-swap capability is necessary to maintain uptime

Key specifications

• Output power: 290W continuous
• Form factor: 1U hot-plug module suitable for rack servers
• Efficiency rating: Platinum-class efficiency
• Cooling: optimized thermal design for efficient heat dissipation in rack environments
• Electrical characteristics: stable voltage and current delivery for server loads

How to use

Install the module into the appropriate power bay of a compatible HP Enterprise chassis or server while the system remains powered, using the hot-plug insertion procedure defined by the server manufacturer. Ensure the module is fully seated and latched, then verify power status indicators on the host system and in management interfaces. For replacement, remove the failed module following ESD precautions and hot-swap guidelines, then insert the new module and confirm proper operation.

Recommendations

Operate the power supply in environments that meet the server manufacturer’s temperature and airflow specifications. Use in redundant configurations where possible to maintain service continuity. Follow ESD handling procedures and consult the host system documentation for supported insertion and removal steps to avoid damage to the module or server.
