The DIMM voltage warnings are generated with some 1.35v LR DIMMs
installed
Problem With some 1.35v LR DIMMs installed, users may see BB 1.35 high, non-
critical/critical messages in the SEL log.
Implication These errors are generated because during boot, DIMMS start at 1.5v. The
BMC reads the voltage and compares it with the SDR threshold for LV DIMMS
(1.35v) and then flags Over Voltage. When the DIMM voltage is shifts down,
the deassertion is logged (~ 5 seconds).
Status This issue may be fixed in a future BIOS/BMC release.
Workaround Ignore this SEL event as there is no functional impact.

Intel® Xeon® processors E-5-4600 v2 Boot Issue
Problem Intel
®
Xeon
®
processors E5-4600 v2 configurations of less than 4 CPUs will not
boot.
Implication Intel
®
Xeon
®
processors E5-4600 v2 configurations of less than 4 CPUs will not
boot due to a mai board CPLD power sequencing issue. This issue does not
impact Intel
®
Xeon
®
processors E5-4600 (non v2) CPUs.
Status All main boards with PBA numbers of less than G49987-503 (S4600LH2) or
G40981-503 (S4600LT2) are impacted by this issue. Main board PBA numbers
with -503 or later have factory updated CPLD firnware that resolves this issue.
Intel is also working on a obtaining a CPLD firmware tool that allows
customers to upgrade the CPLD firmware.
Workaround 4-CPU Intel
®
Xeon
®
processors E5-4600 v2 configurations are not impacted by
this issue. There is currently no field upgradeable utility for the CPLD firmware
update.
