Monthly Specification Update
43. New versions of BMC firmware with previous versions of BIOS cause
system POST failure
Problem In systems updated with newer versions of only the BMC firmware, there is a
high failure rate that they can no longer complete POST successfully.
Implication Any BIOS/BMC/FRU update should adhere to the "SYSTEM FIRMWARE
REQUIREMENTS" in the release notes, where the minimum required versions
are listed. If the release notes recommendations are not followed, unexpected
errors may occur.
Status If the system is going to be updated by system firmware, always follow SFUP
(System Firmware Update Package) to update the BIOS and BMC together.
Always update the FRU after the hardware configuration changes (including
changing the power supply, processor, and system fans).
Workaround No.
44. Intel® Server System SR2500ALLX may operate louder than expected
Problem The Intel
Implication The abnormal noise is caused by the two unbalanced 60-mm system fans #5
and #6. Using a FRUSDR, which is older than v41, also contributes to the
faster fan speed and noise.
Status FRUSDR v41 and later set the maximum fan speed to 75% of the original
maximum value. This change lowers the fan noise and does not break the
thermal condition design specification.
Workaround None.

Red Hat* Enterprise Linux may report the wrong processor speed

Problem In Red Hat* Enterprise Linux, the operating system may report the wrong
processor speed. For example, if the processor is 3.0 GHz, the operating
system shows it as 3300 MHz.
Implication This symptom is operating system-related. Although it does not reflect the
processor speed correctly, this is only a report; it is harmless to the system and
you can ignore it.
Status Ignore the processor speed in Red Hat* Enterprise Linux.
Workaround None.
46. The SuSE* Linux Enterprise Server 10 driver for SAS HW RAID causes
unwanted error logs during installation
®
Server System SR2500ALLX may operate louder than expected.
