ThinkSystem SR650/SR630/SR550 -48V DC Power Supply
The document provides necessary information of the option.
See this document for information about the ThinkSystem SR650/SR630/SR550 -48 V DC Power Supply.
This option kit comes with the following component.
The following illustration shows the LEDs of the power supply.
LEDs of power supply
1 Power input LED
- Green: The power supply is connected to the DC power source.
- Off: The power supply is disconnected from the DC 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.
NOTE
- This type of power supply is only powered by -48 V DC.
- This type of power supply can only be used on the SR650/SR630/SR550 servers.
- Before installing the power supply, user should confirm the technical feasibility with Lenovo.

To remove a hot-swap power supply, complete the following steps:
Watch the procedure. A video of the removal process is available:
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:
Press down the stop bracket 1 and rotate it to the open position.
Rotate the CMA out of the way to gain access to the power supply.
Disconnect the power cord from the hot-swap power supply.
Note: 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, refer to LEDs of Power Supply.
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.
Note:
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
After removing the hot-swap power supply:
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.
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.
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/
NOTE
- 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.
