PMF (Processor Multifunction)
Each processor multifunction (PMF) CRU in a NonStop server contains these components:
• A processor and memory board (PMB), which contains a processor
• A power supply (S7000 only)
• A service processor (SP)
• Three SCSI controllers
• And for PMFs in Group 1 only, an MIOE (Ethernet controller) to provide connectivity between the service processor
and the dedicated service LAN (for OSM).
Location in OSM Tree: System > Group > Module > PMF
Slot Location: PMF CRUs are located in slots 50 and 55 of a processor enclosure (service side).
Example: PMF (1.1.55)

Service State
Physical
A code that identifies the generation of the component. Hardware revision codes are
used for tracking components.
Hardware Revision
Identifies the manufacturer of the component.Manufacturer
The part number of the component that was assigned in manufacturing. Use part
numbers for identifying and ordering parts.
Part Number
Whether the component is powered on. ValuesPower State
A unique serial number that identifies the component.Track IDs are used for tracking
components.
Track ID
Logical
The current voltage of the Fan CRU.Fan Voltage
The voltage of the Main Rail, which supplies power to the CRU from its own power
supply
Main Rail Voltage
This attribute indicates which, if any, ServerNet router ports on this CRU are disabled.
OSM actions to disable or enable a ServerNet port are performed as directed by
OSM alarm repair actions.
Disabled ServerNet Ports
The voltage of the SCSI-Y path, the path configured for mirrored disks on a system.SCSI-Y 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.
MOSFET Voltage
The minimum voltage (39.6 volts) that must be available to power CRU.Rail Minimum Voltage
The voltage of the SCSI-X path, the primary path used for disks on a system.SCSI-X Voltage
The maximum voltage limit (60 volts) for the CRU.Rail Maximum Voltage
The operational voltage of the PMF2 CRU (specifically, the raw voltage supplied to
the DC-to-DC converters).
DCC 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).
