IPMI Sensors
The
CPM
supports
a
variety
of
sensors,
each
with
entries
in
the
Sensor
Data
Records
(SDR).
Table 38
lists
the
IPMI
sensors
supported
by
the
CPM.

OEM Payload Reset Other Sensor
(0xD4)
Sensor-
specific
0x00-0xFF
Used to indicate the cause of payload resets that occur during
standard operation of the CPM.
4
OEM ActBootFlash Other Sensor
(0x0B
Sensor-
specific
0 or 1
Indicates which boot Flash bank the IPMC has currently
selected. If the flash select signal changes state, indicates the
reason.

IPMC Watchdog
OEM (0xED for
IPMC FPGA
WDT)
Digital
N/A
Sensor SDR states that this sensor does not return any analog
readings (a Get Sensor Reading command directed at this
sensor always returns '0' for a reading); however, an "assert"
event is logged to the SEL once the IPMC is reset due to the
Watchdog.
7
EventLogDisabled
Event Logging
Disabled
Sensor-
specific
0x00 - 0x20 Contains hex value from 0 to 100 decimal (00h to 64h)
representing the SEL filled (%) at the time the event was
generated. 00h is 0% full (SEL is empty), 64h is 100% full, etc.
