The following illustration shows the LEDs of the power supply.
Figure 2. LEDs f p wer supply
LED Description
1 Power input LED • Green: The power supply is connected to the ac power source.
• Off: The power supply is disconnected from the ac power source or a power problem
occurs.
2 Power output LED • Green: The server is on and the power supply is working normally.
• Blinking green: The power supply is in the zero-output mode (standby). When the
server power load is low, one of the installed power supplies enters the standby state
while the other one delivers the entire load. When the power load increases, the
standby power supply will switch to the active state to provide sufficient power to the
server.
To disable the zero-output mode, start the Setup utility, go to System Settings ➙
Power ➙ Zero Output, and select Disable. If you disable the zero-output mode, both
power supplies will be in the active state.
• Off: The server is turned off, or the power supply is not working properly. If the server is
turned on but the power output LED is off, replace the power supply.
3 Power supply error LED • Yellow: The power supply has failed. To resolve the issue, replace the power supply.
• Off: The power supply is working normally.

Step 1. If the server is in a rack, adjust the cable management arm (CMA) to gain access to the power
supply bay.
If you have installed the 2U CMA Upgrade Kit for Toolless Slide Rail or Toolless Slide Rail Kit with
2U CMA, do the following:
Figure 4. CMA adjustment
a. Press down the stop bracket 1 and rotate it to the open position.
b. Rotate the CMA out of the way to gain access to the power supply.
Step 2. Disconnect the power cord from the hot-swap power supply.
ote: If you are replacing two power supplies, do the power supply replacement one by one to
ensure that the power supply to the server is not interrupted. Do not disconnect the power cord
from the secondly replaced power supply until the power output LED for the firstly replaced power
supply is lit. For the location of the power output LED, rFigure 2 “LEDs of power supply” on page
2efer to .

Step 3. Press the release tab toward the handle and carefully pull the handle at the same time to slide the
hot-swap power supply out of the chassis.
ote:
Slightly pull the power supply upwards when sliding the power supply out of the chassis, if you
have installed one of the following CMA kits:
• 2U CMA Upgrade Kit for Toolless Slide Rail
• Toolless Slide Rail Kit with 2U CMA
Figure 5. H t-swap p wer supply rem val
After removing the hot-swap power supply:
1. Install a new power supply or install the power-supply filler to cover the power supply bay. For more
information, refer to “Install a hot-swap power supply” on page 7.
Important: To ensure the proper cooling during the normal server operation, both of the power supply
bays must be occupied. It means that each bay must have a power supply installed; or one has a power
supply installed and the other has a power supply filler installed.
2. If you are instructed to return the old hot-swap power supply, follow all packaging instructions and use
any packaging materials that are provided.

The following tips describe the type of power supply that the server supports and other information that you
must consider when you install a power supply:

• The standard shipping has only one power supply installed in the server. For redundancy and hot-swap
support, you must install an additional hot-swap power supply. Certain customized models might be
shipped with two power supplies installed.
• Ensure that the devices that you are installing are supported. For a list of supported optional devices for
the server, go to:
http://www.lenovo.com/us/en/serverproven/
otes:
• Ensure that the two power supplies installed on the server have the same wattage.
• If you are replacing the existing power supply with a new power supply of different wattage, attach the
power information label that comes with this option onto the existing label near the power supply.

Before installing a hot-swap power supply, touch the static-protective package that contains the new hot-
swap power supply to any unpainted surface on the outside of the server. Then, take the new hot-swap
power supply out of the package and place it on a static-protective surface.
To install a hot-swap power supply, complete the following steps:
Watch the procedure. A video of the installation process is available:
• Youtube: https://www.youtube.com/playlist?list=PLY 5R7h cs-A25P7vBoGa_wn7D7XTgDS_

Step 1. If the server is in a rack, adjust the cable management arm (CMA) to gain access to the power
supply bay.
If you have installed the 2U CMA Upgrade Kit for Toolless Slide Rail or Toolless Slide Rail Kit with
2U CMA, do the following:
Figure 7. CMA adjustment
a. Press down the stop bracket 1 and rotate it to the open position.
b. Rotate the CMA out of the way to gain access to the power supply bay.

Step 2. Note the orientation and slide a power-supply filler is installed, remove it.
Figure 8. H t-swap p wer supply filler rem val
Step 3. Slide the new hot-swap power supply into the bay until it snaps into position.
Figure 9. H t-swap p wer supply installati n
After installing the hot-swap power supply:
1. Connect one end of the power cord to the new power supply connector; then, connect the other end of
the power cord to a properly grounded electrical outlet.
2. If the server is turned off, turn on the server. Ensure that both power input LED and the power output
LED on the power supply are lit, indicating that the power supply is operating properly. For the location
of the power supply LEDs, refer to Figure 2 “LEDs of power supply” on page 2.
