The hot-swap redundant power supplies help you avoid signicant 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.
