Customer Messaging Policy - HP AB464-9003F Service Manual

Customer Messaging Policy

Only light a diagnostic LED for memory DIMM errors when isolation is to a specific memory
DIMM. If any uncertainty about a specific DIMM, point customer to the SEL for any action
and do not light the suspect DIMM CRU LED on the diagnostic panel.
For configuration style errors, for example, no memory DIMMs installed in rank 0 of side 0,
follow the Hewlett Packard Enterprise policy of lighting all of the CRU LEDs on the diagnostic
LED panel for all of the DIMMs that are missing.
No diagnostic messages are reported for single-byte errors that are corrected in both zx2
caches and memory DIMMs during corrected platform error (CPE) events. Diagnostic
messages are reported for CPE events when thresholds are exceeded for both single-byte
and double byte errors; all fatal memory subsystem errors cause global MCA events.
PDT logs for all double byte errors will be permanent; single byte errors will initially be logged
as transient errors. If the server logs 2 single byte errors within 24 hours, upgrade them to
permanent in the PDT.
Table 54 lists the memory subsystem evens that light the diagnostic panel LEDs.

Cause Source
Voltage on memory BMC
expander is
inadequate
No memory DIMMs SFW
installed (in rank 0 of
cell 0)
A DIMM has a serial SFW
presence detect
(SPD) EEPROM with
a bad checksum
This memory rank is WIN
correcting too many Agent
single-bit errors
Cause Source
Unable to clear the SFW
platform error logs in
CEC
Self-test of CEC SFW
multi-bit error
signaling has failed
The CEC failed the SFW
register test
Notes
A voltage on the
memory
expander is out
of range (likely
too low)
Light all DIMM
LEDs in rank 0
of cell 0
Either EEPROM
is
misprogrammed
or this DIMM is
incompatible
Memory rank is
about to fail or
environmental
conditions are
causing more
errors than
usual
