planner. The Distributed Systems Management/Software Configuration Manager
(DSM/SCM) user who is responsible for planning and managing new software
revisions. The planner uses the DSM/SCM Planner Interface to carry out these
functions.
Planner Interface. A graphical user interface (GUI) to the Distributed Systems
Management/Software Configuration Manager (DSM/SCM) that runs on the host
system. It provides an interface to all the host DSM/SCM planner functions.
plug-in card (PIC). A replaceable component that provides a unique function when
installed in a customer-replaceable unit (CRU) or field-replaceable unit (FRU). PICs
for modular ServerNet expansion boards (MSEBs) and I/O multifunction (IOMF) 2
CRUs provide a choice of connection media for attaching ServerNet cables.
PM. See product module (PM).
PMB. See processor and memory board (PMB).
PMCU. See power monitor and control unit (PMCU).
PMF CRU. See processor multifunction (PMF) CRU.
PMF 2 CRU. See processor multifunction (PMF) 2 CRU.
pNA+. The support for the Transmission Control Protocol/Internet Protocol (TCP/IP) layers
and the Ethernet interface provided by Integrated Systems Inc. as part of the Portable
Silicon Operating System (pSOS) system product. pNA+ is provided as part of the
wide area network (WAN) architecture in each ServerNet wide area network (SWAN)
concentrator communications line interface processor (CLIP).
Point-to-Point Protocol (PPP). A data communications protocol that provides a standard
method of encapsulating Transmission Control Protocol/Internet Protocol (TCP/IP)
information over point-to-point links. The Compaq TSM package uses PPP to provide
TCP/IP communication over a dial-up connection.
POOL object type. The Subsystem Control Facility (SCF) object type for Storage
Management Foundation (SMF) storage pools.
port. (1) A data channel that connects to other devices or computers. (2) A connector to
which a cable can be attached. The system transmits and receives data or requests
through ports on ServerNet adapters and processor multifunction (PMF) customer-
replaceable units (CRUs). A port is also called a connector. (3) The entrance or
physical access point (such as a connector) to a computer, multiplexer, device, or
network where signals are supplied, extracted, or observed.
