Power supplies
The hot-swap redundant power supplies help you avoid significant interruption to the operation of the
system when a power supply or an input power source fails. A failed power supply can be replaced without
turning off the server. You can purchase a power supply option from Lenovo and install the power supply to
provide power redundancy or additional power capacity without turning off the server.
