Key specifications
 Brand: Supermicro
 Model / MPN: PWS-651-1R-RFB
 Output power: 650W
 Feature: Hot-swap, redundant power supply module
 Intended use: Replacement or spare unit for compatible Supermicro chassis
How to use
Install the PWS-651-1R-RFB into the compatible Supermicro chassis power bay per the chassis service manual. When the server supports redundant power, insert the module alongside the existing supply; the hot-swap capability allows insertion or removal while the system remains powered, provided the other redundant supply is active. For replacement, power down according to your maintenance procedures if redundancy is not present, remove the failed module, and slide the PWS-651-1R-RFB into the bay until it engages securely. Verify proper seating and connection, then monitor system indicators or management tools to confirm the supply is recognized and operating normally.
Usage recommendations
For optimal availability, keep a compatible spare PWS-651-1R-RFB on-site and verify firmware and chassis compatibility before deployment. Follow Supermicro chassis guidelines for airflow orientation and service procedures, and observe electrostatic discharge precautions when handling the module.
