During normal operations, the Intel® Remote Management Module 2 (Intel® RMM2) and the server Baseboard Management Controller (BMC) routinely exchange management communications. The same bus used for Intel RMM2 to BMC communication is used to update the Hot Swap Controller (HSC) firmware. Beginning with Intel RMM2 firmware version 5990, the communication occurring on the path to the BMC will slow the communication to the HSC and may cause the HSC upgrade to fail. Firmware updates for the BMC are not impacted.
