Appendix B: Sensor Tables Intel® Compute Module MFS5000SI TPS 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: ƒ 'A': Auto rearm ƒ '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. Table 15.
