Power supply module Dell 750W redundant hot-swap 5NF18 for servers

The Dell 750W redundant hot-swap power supply module provides 750 watts of AC-to-DC power in a removable, hot-swappable form factor intended for rack and tower server chassis. Designed for use in redundant power configurations, this module lets technicians replace failed units without powering down the server, supporting higher availability and simplified maintenance in data center and enterprise environments.

Advantages

The module’s hot-swap capability enables live replacement to maintain system uptime during service operations. Redundant-ready design supports parallel installation with other power modules to provide failover protection. The compact, guided rail form factor ensures secure insertion and easy removal, while built-in status indicators allow quick visual checks. The unit delivers consistent power output suited for server components and adheres to enterprise reliability expectations.

Suitable for

• Enterprise and data center servers requiring redundant power
• Server racks where online maintenance and minimal downtime are required
• IT infrastructure with hot-swap capable chassis
• Replacement of failed or aging power modules to restore redundancy

Key specifications

• Output power: 750 W
• Form factor: removable hot-swap power module compatible with enterprise server chassis
• Intended use: AC input to DC server power conversion for internal server components
• Cooling: chassis-integrated airflow compatible design (front-to-back or as specified by server)
• Indicators: front-panel status LEDs for presence and fault indication
• Mounting: guided insertion rails for tool-less removal and installation

How to use

Install the module into a compatible server power bay following the server manufacturer’s service procedure. Ensure the server chassis is configured for redundant power or that a second functional module is present if required. Slide the module into its bay until it seats and the retention latch engages; check front-panel LEDs to confirm presence and normal operation. To replace a failed unit, remove the faulty module by releasing the latch and sliding it out while the server remains powered, then insert the replacement and verify status indicators.Follow any server-specific procedures for load balancing or power sequencing as described in the server’s maintenance documentation.

Recommendations

Use this power module in systems explicitly listed as compatible by the server manufacturer and ensure firmware and power configuration settings match the deployed hardware. Store spare modules in a dry, dust-free environment and avoid touching connector pins. For critical systems, maintain at least one redundant module installed and perform periodic visual inspections of status LEDs and connectors.
