3 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.

6 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.

specific
0x00-0xFF Bit [7] = IPMB B Override State
Bit [6:4] = IPMB B Local Status
Bit [3] = IPMB A Override State
Bit [2:0] = IPMB A Local Status

0x00-0xFF Bit [7:4] = Reserved
Bit [3] = IPMB-L Override State
Bit [2:0] = IPMB-L Local Status
10 Ejector Closed Slot or
Connector
Digital 1 0 = Eject latch is open. Fault Status asserted
1 = Eject latch is closed. Identify Status asserted
11 RTM Present Slot or
Connector
Digital 0 or 1 0 = RTM is not present
1 = RTM is present
12 ENET Link 0 Slot or
Connector
Digital 0 or 1 0 = E0_LINK* not asserted
1 = E0_LINK* asserted
