Bmc And Drac5 Firmware Version Requirements; Back Cooling Fans - Dell PowerEdge R900 Series Information Update

BMC and DRAC5 Firmware Version Requirements

When upgrading either the BMC or the DRAC5, you must update the
firmware for both components to ensure full functionality and compatibility.
For example, the power reduction feature of the DRAC5 version 1.40
firmware works only when BMC 2.27 or higher is also installed. If the BMC
and DRAC firmware are incompatible—BMC 2.27 installed with DRAC5
version 1.33 or BMC 1.79 installed with DRAC5 version 1.40—the power
reduction feature may not function correctly.

Back Cooling Fans

Systems manufactured after September 2008 no longer include the four back
cooling fans installed in earlier systems. Therefore, BMC version 2.27 does
not recognize the presence of back fans. The back fans will still run in older
systems; however, from a system perspective, the fans do not exist and are
not monitored. As a result, if the back fans fail, the SEL, server management
software, and remote access card will not log the error. This change does not
compromise the standard hot plug and redundancy features of the front fans.
