Installing or replacing a hot-swap redundant power supply

Depending on the model, your server might come with one or two hot-swap redundant power supplies.
When the server is populated with two hot-swap redundant power supplies, the server can withstand a
power loss from either power supply. This helps you avoid significant interruption to the operation of the
server when a power supply fails. You can replace the failing hot-swap redundant power supply without
turning off the server.
Some server models come with only one power supply. You can purchase a hot-swap redundant power
supply from the Lenovo Web site at:

CAUTION:
Hazardous moving parts. Keep fingers and other body parts away.
CAUTION:
Never remove the cover on a power supply or any part that has the following label attached.
Hazardous voltage, current, and energy levels are present inside any component that has this label
attached. There are no serviceable parts inside these components. If you suspect a problem with
one of these parts, contact a service technician.
Notes:
• To maintain the EMI integrity and cooling of the server, install a new power supply as soon as you remove
the failing one. Cover the other bay with a shield if you just use one power supply to provide power.
• Use any documentation that comes with the new power supply and follow those instructions in addition
to the instructions in this topic.
