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

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 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 operating system. The primary
processor is the processor that has direct control over the SAC.
See also backup processor.
primitive state
The state of a PE that is not a member of the voting set of PEs. In this state the PE cannot
perform any I/O, voting or rendezvous. It may communication with other PEs using
primitive communication mechanisms.
problem incident report
A type of incident report that notifies you of a problem on your server or ServerNet
cluster. A problem incident report is generated when changes occur that could directly
affect the availability of resources. Problem incident reports include the system
configuration file and might include other attachments, such as alarm logs and processor
diagnostic information.
See also periodic incident report.
processor
A functional unit of a computer that reads program instructions, moves data between
processor memory and the input/output controllers, and performs arithmetic operations.
Processors are sometimes referred to as central processing units (CPUs), but a NonStop
server has multiple cooperating processors rather than a single CPU.
processor and memory board (PMB) CRU
Part of the processor multifunction (PMF) CRU. A logic board that has the following
computer chips: lockstepped microprocessors, the main memory system, and the
ServerNet memory interface.
processor board
A board that contains the set of processor elements in a Blade Element.
processor multifunction (PMF) CRU
A NonStop S-series customer-replaceable unit (CRU) that contains a power supply,
service processor (SP), ServerNet router 1, Ethernet controller, three ServerNet
addressable controllers ( SACs), and a processor and memory system in a single unit. The
PMF CRU consists of three subassemblies: the processor and memory board ( PMB), the
