serial maintenance bus (SMB) domain
power interface board (PIB)
A board mounted on the bulkhead located behind the power supplies in NonStop S7x000
and S7400 processor
. The PIB provides electrical connection between the
power supplies and DC power cables.
power monitor and control unit (PMCU) FRU
that connects the batteries to the DC power distribution
and provides a means of disconnecting the batteries for powering off
the system. The PMCU also enables the
to diagnose the condition
of the associated fan and power supply and to regulate the voltage supplied to the fans. It
also provides the interface to the
identification switches and service
are two PMCUs in each group, one for each of the two DC power distribution buses.
power supply
In system enclosures without power shelves, the component on the
multifunction (PMF) customer-replaceable unit (CRU)
that converts standard AC line voltage into the DC voltages needed by the group
components in the enclosure.
In system enclosures with power shelves, the component located in the power shelf that
converts standard AC line voltage into DC voltage and delivers it to the PMF CRUs or
IOMF CRUs in that enclosure, which in turn supply the DC voltages needed by the group
components in the enclosure.
primary processor
The processor that is designated as owning the
ServerNet addressable controller (SAC)
connected to separate processors running the NonStop Kernel operating system. The
primary processor is the processor that has direct control over the SAC.
