Power supply 1-4
Note:
Power supply 2-4 are optional.
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.
For information about minimum power supply requirements and power redundancy, see “power supply
criteria in the “Install a power supply” topic” on page 245.
Each hot-swap power supply has three status LEDs. See “Rear view LEDs” on page 33 for information.
