OEM Sensors Shm Fault Event (Emerson OEM)

3.1.6Shm 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.

zSensor 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.

z Current State Mask - 0x1FE - mask of possible fault event bits

zEvents - For FTM-related faults, an event is generated when any FTM transitions into or out of a fault condition. An event is flagged as an assertion event when at least one FTM exhibits the fault class. It is flagged as a deassertion event when no FTMs remain with the fault class.

Table 3-1 Shm Fault Classes

Fault
Class	Meaning
0	Not used.
1	One or more fan trays are missing.
2	One or more fan trays' speed sensors are below critical threshold.
	By default, all of a FTM's speed sensors must be below critical speed in order to declare a
	fault at that FTM; however through a new configuration option in shelfman.conf, the
	administrator can change the behavior to declare a fault if any speed sensor is critical.
3	One or more fan trays' speed sensors do not show significant increase when the active shelf
	manager asserts FULL_SPEED signal as part of the Fan Tray Latent Fault Check algorithm.
	(Active FULL_SPEED test)
4	One or more fan trays' speed sensors do not return to a normal speed following the release
	of FULL_SPEED signal by the active shelf manager, as part of the Fan Tray Latent Fault
	Check algorithm. (Active FULL_SPEED test)
5	One or more fan trays' speed sensors do not show significant increase when the redundant
	shelf manager asserts FULL_SPEED signal as part of the Fan Tray Latent Fault Check
	algorithm. (Redundant FULL_SPEED test)
6	One or more fan trays' speed sensors do not return to a normal speed following the release
	of FULL_SPEED signal by the active shelf manager, as part of the Fan Tray Latent Fault
	Check algorithm. (Redundant FULL_SPEED test)
7	One or more fan trays' speed sensors do not show significant increase when the active shelf
	manager increases the speed level to its maximum value as part of the Fan Tray Latent
	Fault Check algorithm. (PSOC LFC test)
8	One or more fan trays' speed sensors do not return to a normal speed following the lowering
	of the speed level by the active shelf manager, as part of the Fan Tray Latent Fault Check
	algorithm. (PSOC test)
