OSM Service Connection User's Guide (G06.30+)

MOSFET Voltage
The voltage measured between the MOSFET switch and the diode to the
DCC. The MOSFET switch is located on the Other Rail between the
alternate power supply and the DCC.
Rail Minimum Voltage The minimum voltage (39.6 volts) that must be available to power CRU.
SCSI-X Voltage
The voltage of the SCSI-X path, the primary path used for disks on a
system.
Rail Maximum Voltage The maximum voltage limit (60 volts) for the CRU.
DCC Voltage
The operational voltage of the PMF2 CRU (specifically, the raw voltage
supplied to the DC-to-DC converters).
Other Rail Voltage
The voltage of the Other Rail, which connects the PMF/IOMF CRU to
the other power supply in the enclosure (to provide power in the event of
a problem with the Main Rail power supply).
Storage ASIC
Initialization State
The status of the storage ASIC in the CRU.
Values: Initialized, Uninitialized, Unknown
Actions
Disable ServerNet Port
Disables the specified ServerNet port on this CRU. Perform this action only as directed by OSM
alarm repair actions.
Parameter: Port Number
Enable ServerNet Port
Enables the specified ServerNet port on this CRU. Perform this action only as directed by OSM
alarm repair actions.
Parameter: Port Number
Force Power Off
Use this action to power off the CRU and all of its subcomponents only if the Prepare to Power Off
or Power Off actions fail. The Force Power Off does not perform the other precautionary checks that
are done by the Prepare to Power Off and Power Off actions. However, these steps are taken:
If the SP on this PMF CRU is designated as Active (Primary), resets the SP so the peer SP
becomes primary instead
