PowerEdge: How to disable the third-party PCIe Card default cooling response on PowerEdge 13G Servers

Summary: This article explains how to disable the third-party PCIe Card default cooling response on PowerEdge 13G Servers.

This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Symptoms

The default automatic cooling response on the PowerEdge 13G server for third-party PCIe cards provisions airflow based on common industry card requirements. Based on that industry standard, our thermal algorithm targets delivery of a maximum of 55C inlet air to the PCIe card region. 

For some cards that may not need additional cooling above the baseline (such as ones with their own fan), Dell has enabled an OEM IPMI-based command to disable this default fan response to the new PCIe card.

The ability to disable this feature only removes the fan response associated with the addition of a third-party PCIe card and does not compromise original thermal algorithm-based cooling needs. If the fan speeds were already high due to other system needs, then disabling this feature may have no effect.

Cause

The default automatic cooling response on the PowerEdge 13G server for third-party PCIe cards provisions airflow based on common industry card requirements. Our thermal algorithm targets delivery of maximum 55C inlet air to the PCIe card region based on that industry standard.

Resolution

ENABLE/DISABLE Third-Party PCIe card-based default system fan response: 

  1. Download and install OpenManage BMC Utility.

  2. Enable the "IPMI over LAN" in the iDRAC of the target machine, this can be done using iDRAC Web user interface or BIOS Setup.

  3. Go to the installation folder of OpenManage BMC Utility, and run the following commands:

Set Third-Party PCIe Card Default Cooling Response Logic To Disabled

ipmitool -I lanplus -H <IPADDRESS> -U <USERNAME> -P <PASSWORD> raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x01 0x00 0x00


Set Third-Party PCIe Card Default Cooling Response Logic To Enabled

ipmitool -I lanplus -H <IPADDRESS> -U <USERNAME> -P <PASSWORD> raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x00 0x00 0x00 


Get Third-Party PCIe Card Default Cooling Response Logic Status.

ipmitool -I lanplus -H <IPADDRESS> -U <USERNAME> -P <PASSWORD> raw 0x30 0xce 0x01 0x16 0x05 0x00 0x00 0x00


The response data is:

16 05 00 00 00 05 00 01 00 00 (Disabled)
16 05 00 00 00 05 00 00 00 00 (Enabled)
