HP Integrity NonStop J-Series - Manual (Page 185)

PMCU
The power monitor and control unit (PMCU) controls and monitors the battery connection to the
DC power distribution buses. Along with the service processor, the PMCU diagnoses the condition
of the batteries, fans, and power supplies and regulates the voltage supplied to the fans.
Location in OSM Tree: System > Group > Module > PMCU
Slot Location: PMCUs are located in slots 21 and 22 of Nonstop S-series I/O enclosures
(appearance side).
Example: PMCU (1.1.21)

Values
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. Values Power State
A unique serial number that identifies the component. Track IDs are used for
tracking components. Track ID
Temperature Sensor
The minimum acceptable air intake temperature is 5 degrees Celsius. If the
temperature falls below 5 degrees, an alarm is generated. Normal Minimum Value
The current temperature, in degrees Celsius (°C), inside the enclosure of the
module. Current Value
The maximum acceptable air intake temperature is 50 degrees Celsius. If
the temperature rises above 50 degrees, an alarm is generated. Normal Maximum Value
Actions
None.
Power Supply
The power supply converts standard AC line voltage and distributes DC power to all components
in its power domain. The power supply is a separate CRU for enclosures containing
IOMF2 CRUs.
In DC-powered Telco systems, the power supply units displayed in slots 31 and 32 of the OSM
GUI represent up to 4 Telco Isolating Converters (TICs) in positions A1, A2, B1, and B2. For
information on installing or replacing power components in a Telco system, see the NonStop
S-Series Central Office Server Installation and Service Guide.
