Install a power supply unit
Use this information to install a power supply.
About this task
The following describes the information that you must consider when installing a power supply: 
•  The server is shipped with only one power supply by default. In this case, the power supply is non-hot- 
swap and before removing it, you must turn off the server first. To support redundancy mode or hot-swap, 
install an additional hot-swap power supply. 
•  If you are replacing the existing power supply with a new power supply:  
–  Use Lenovo Capacity Planner to calculate the required power capacity for what is configured for your 
server. More information about Lenovo Capacity Planner is available at:
https://datacentersupport.lenovo.com/solutions/lnvo-lcp
–  Ensure that the devices that you are installing are supported. For a list of supported optional devices for 
the server, go to:  
https://static.lenovo.com/us/en/serverproven/index.shtml
–  Attach the power information label that comes with this option onto the existing label near the power 
supply.

Attention: 
•  Read “Installation Guidelines” on page 185 to ensure that you work safely.
•  Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static- 
sensitive components in their static-protective packages until installation, and handling these devices with 
an electrostatic-discharge wrist strap or other grounding system.

Procedure
Step 1.  Touch the static-protective package that contains the hot-swap power supply to any unpainted 
surface on the outside of the server. Then, take the hot-swap power supply out of the package and 
place it on a static-protective surface.
Step 2.  If there is a power-supply filler installed, remove it.
