OEM Sensors 3.1.6 Shm Fault Event (Emerson OEM) Shm Fault Event (Emerson OEM) This sensor reports the status of Fault Classes on the Active shelf. When the value is read it indicates the presence or absence of each fault class. Currently defined fault classes relate to the health of the FTMs in the shelf. z Sensor Reading - This is a 2-byte bit mask of active fault conditions detected by the sensor. A '1' in any bit indicates the specified fault is active. Refer to the following table for fault classes.

A System Behavior in Response to Sensor Events A.1 A Introduction This chapter introduces important information for those who are developing their own applications code, based on how the Centellis 3406 and 3600 system behaves to different events. A.2 Cooling Management in Normal Operation Mode The Shelf Manager operates in normal mode with respect to cooling if no temperature sensor in the shelf reports crossing of one of the upper thresholds (noncritical, critical or nonrecoverable).
PAGE 142
System Behavior in Response to Sensor Events Adaptive Adjustment of the Minimum Fan Level When at least one nonrecoverable temperature threshold has been exceeded on a FRU, the Shelf Manager powers down the FRU (sending them the SetPowerLevel(0) command) and refuses to power the FRU back up for COOLING_POLL_TIMEOUT* seconds. In that state, the Shelf Manager also immediately raises the level of all fans to the maximum level and keeps it at maximum. A.
PAGE 143
Adaptive Adjustment of the Minimum Fan Level System Behavior in Response to Sensor Events The following graph illustrates the behavior of the above cooling algorithm in finding a stable fan level in real shelf, in the presence of a substantial thermal load in the shelf. The configuration parameter NORMAL_STABLE_TIME* is set to 30 minutes. The graph presents the fan speed changes over a period of 70 minutes. The horizontal axis has time scaled from 0 to 70 minutes.
