Power supply Dell 350W redundant 9WR03 for server systems, hot‑swap compatible

Redundant Dell 350W power supply module designed for compatible Dell server systems. This hot-swap compatible unit delivers up to 350 watts of output to support server power needs and provides a redundant power source to maintain system availability during maintenance or component failure. The module is intended for installation in server chassis that accept this form factor and connector layout, allowing replacement without powering down the system.

Advantages

The module supports hot-swap replacement, enabling quick removal and installation while the server remains operational. Its redundant configuration capability helps reduce downtime by providing an immediate backup power path if a primary supply fails. The compact design and standardized connector make the unit suitable for dense rack environments and data center deployments where space and serviceability are important. Built to meet server-grade electrical and thermal requirements, the supply contributes to predictable system behavior under load.

Suitable for

• Enterprise and data center server racks requiring redundant power
• IT maintenance scenarios where hot-swap replacement is needed
• Systems that require continuous operation during power supply servicing

Key specifications

• Rated output power: 350 W
• Compatibility: designed for compatible Dell server chassis accepting this module form factor
• Mounting: hot-swap / hot-plug capable module for tool-less replacement
• Cooling: integrated fan-assisted cooling suitable for rack environments
• Voltage input: designed for standard server AC mains input ranges (auto-sensing)

How to use

Confirm the server chassis supports this 350W redundant power module and follow the server manufacturer's instructions for hot-swap replacement. To install, latch the module into the appropriate bay until it seats and the retention mechanism engages; the server's management interface or front-panel indicators will confirm proper insertion and power status. For removal, follow the documented hot-swap procedure: notify system management, verify the unit is not reporting faults as the active supply, then release the retention mechanism and slide the supply out. Use an identical or compatible replacement to maintain redundancy.

Usage recommendations

Use this power module in matched pairs or the server's recommended redundant configuration to ensure continuous operation. Verify firmware and system management settings for power redundancy alerts, and keep spare modules accessible for rapid replacement. Install in an environment with proper airflow and ambient temperature control to maintain performance and longevity.
