Hot-swap redundant power supply 1

The hot-swap redundant power supplies help you avoid significant interruption to the operation of the system when a power supply fails. You can purchase a hot-swap redundant power supply option from Lenovo and install the power supply to provide power redundancy without turning off the server.

On each hot-swap redundant power supply, there is a status LED near the power cord connector. When the LED is lit in green, it indicates that the hot-swap redundant power supply is working correctly. When the LED is lit in amber, it indicates that the hot-swap redundant power supply is likely to fail or has failed.
