Steps to disable/enable power supply cold redundancy for Intel® Server
How do I disable power supply cold redundancy for Intel® Server?
There are 2 ways to disable/enable cold redundancy:
- Using the Syscfg utility (local only):
- Download the latest Syscfg utility
- Unzip the file to USB drive
- Boot the system into EFI shell
- Run the following command:
- To Disable : syscfg.efi /cr disable
- To Enable : syscfg.efi /cr enable
- Using the IPMI command (local or remote):
- Download and/or install the desired IPMI utility
- Run the following command:
- To disable:
- ipmitool –I lanplus –H bmc_ip –U bmc_username –P bmc_password raw 0x30 0x2d 0x01 0x00
- ipmiutil cmd -F lan2 –T 4 –V 4 –N bmc_ip –U bmc_username –P bmc_password 0 20 c0 2d 1 0
- To enable:
- ipmitool –I lanplus –H bmc_ip –U bmc_username –P bmc_password raw 0x30 0x2d 0x01 0x01
- ipmiutil cmd -F lan2 –T 4 –V 4 –N bmc_ip –U bmc_username –P bmc_password 0 20 c0 2d 1 1
- To get current state:
- ipmitool –I lanplus –H bmc_ip –U bmc_username –P bmc_password raw 0x30 0x2e 0x01
- ipmiutil cmd -F lan2 –T 4 –V 4 –N bmc_ip –U bmc_username –P bmc_password 0 20 c0 2e 1
- The get command returns 2 bytes of data, the second byte indicates if cold redundancy is enabled (01) or disabled (00).
The following example shows cold redundancy is disabled:
PS C:\IPMItool-1.8.11.i2-win> .\ipmitool.exe raw 0x30 0x2e 0x01
01 00
- To disable:
| Note |
Baseboard Management Controller (BMC) of the target system must be configured for remote access to use the above commands. If BMC is not configured, it is possible to run the IPMI commands from the host operating system on the target system via the in-band interface by omitting the command options such as IP address and credential of the BMC. |

Note |
Intel® Server's Integrated Baseboard Management Controller (BMC) can be accessed by standard, off-the-shelf terminal, open-sourced, or terminal emulator utilities. One example is the IPMIUtility that allows access to sensor status information and power control. Customers own the risk of using open-source utilities. Intel has no control on these utilities and cannot guarantee any fix with these utilities. |
Cold Redundancy is also known as Low-Power State, which is increased power usage efficiency when system loads are such that both power supplies are not needed at the same time. When in Cold Redundant mode, only the needed power supply, to support the best power delivery efficiency, is ON.
