How to use

Before replacing the power supply, power down the server according to the manufacturer’s service procedures and disconnect AC input cables. Verify the replacement unit's MPN (01PF504-RFB) and compatibility with your ThinkSystem model. Install the power supply into the server chassis following Lenovo’s service manual guidance, secure mounting points and reconnect AC power to the appropriate voltage source (230V or 115V). After installation, power on the server and confirm proper operation through system LEDs and management interfaces. If the server supports hot-swap PSUs, follow the hot-swap procedure to replace the unit without full system shutdown.

Recommendations

Maintain a stock of compatible spare 1100W PSUs for critical systems, verify firmware and hardware compatibility before installation, and use qualified personnel for replacement to ensure safe handling and to preserve system integrity. Dispose of the old power supply according to local electronic waste regulations.
