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 power supply option from Lenovo and install the
power supply to provide power redundancy without turning off the server.
On each power supply, there are three status LEDs near the power cord connector. For information about
the status LEDs, see “Power supply status LEDs” on page 51.
