Fault LED

This column indicates whether an assertion of an event lights the front panel fault LED. The

Integrated BMC aggregates all fault sources (including outside sources such as the BIOS) such

that the LED will be lit as long as any source indicates that a fault state exists. The Integrated

BMC extinguishes the fault LED when all sources indicate no faults are present.

Sensor Rearm

The rearm is a request for the event status for a sensor to be rechecked and updated upon a

transition between good and bad states. Rearming the sensors can be done manually or

automatically. The following abbreviations are used in the column:

'A': Auto rearm

'M': Manual rearm

Readable

Some sensors are used simply to generate events into the System Event Log. The Watchdog

timer sensor is one example. These sensors operate by asserting and then immediately de-

asserting an event. Typically the SDRs for such sensors are defined such that only the assertion

causes an event message to be deposited in the SEL. Reading such a sensor produces no

useful information and is marked as 'No' in this column. Note that some sensors may actually be

unreadable in that they return an error code in response to the IPMI Get Sensor Reading

command. These sensors are represented by type 3 SDR records.

Standby

Some sensors operate on standby power. These sensors may be accessed and/or generate

events when the compute module payload power is off, but standby power is present.
