p[0..1].d[0..7].fail
Each CPU has eight associated DIMM sockets.
These LED indicator sensors show the state of the corresponding CPU’s DIMM Y
fault LED that is illuminated in response to ECC errors. This DIMM is part of PAIR
0 that also includes p0.d1.fail as part of the same 128-bit ECC memory pair. Both
LEDs in the same pair will be illuminated at the same time when one indicates a
fault.
CPU [0..1] Fan Control Temperature Sensors
Temperature sensors in this category are used as inputs to the fan control algorithm
and are used to turn the system power off if they are non-recoverable. Their state
also affects the state of the front panel LEDs.

Description
0x0001
Predictive Failure
Deasserted
No
This state indicates that the CPU
X
DIMM Y Fault
LED is OFF.
0x0002
Predictive Failure
Asserted
Yes
This state indicates that the CPU
X
DIMM Y Fault
LED is ON. It is illuminated in response to a single
Uncorrectable ECC error or more than 24 correctable
ECC errors in 24 hours. ECC errors are reported to the
service processor from the BIOS. When active, the
System Alert LED should also blink SLOW.
