Install a hot-swap power supply unit
Use this information to install a hot-swap power supply unit.
About this task
If the power supply unit to be removed is the only one installed, the power supply unit is not hot-swappable. Before removing it, you must turn off the server first. To support redundancy mode or hot-swap, install an additional hot-swap power supply unit.
- 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: Lenovo Capacity Planner website
- Ensure that the devices that you are installing are supported. For a list of supported optional devices for the server, go to: Lenovo ServerProven website
Attach the power information label that comes with this option on the existing label near the power supply.

Never remove the cover on a power supply or any part that has this 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.
To avoid a shock hazard:
- Connect all power cords to a properly wired and grounded electrical outlet/source.
- Connect any equipment that will be attached to this product to properly wired outlets/sources.
- When possible, use one hand only to connect or disconnect signal cables.
- Never turn on any equipment when there is evidence of fire, water, or structural damage.
- The device might have more than one power cord, to remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

Read Installation Guidelines and Safety inspection checklist 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 systems.
Procedure
After you finish
If you have adjusted the CMA to gain access to the power supply bay, readjust the CMA back in place.
If the server is turned off, turn on the server. Ensure that both the power input LED and the power output LED on the power supply unit are lit, indicating that the power supply unit is operating properly.
