Glossary
private loop
A private loop is not connected to a switched fabric, and the switch's embedded expansion port
(E_Port) and fabric loop port (FL_Port) are inactive. All devices attached to the loop can only
communicate with each other. Contrast with public loop.
Product Manager application
Application that implements the management user interface for a Director or Switch. There are
two Product Manager applications: Director or Switch Product Manager, and HAFM Product
Manager. (1) In the HAFM Management Services application, the software component that
provides a graphical user interface for managing and monitoring HAFM products. When a
product instance is opened from the HAFM application Product view or Fabric Manager
Topology view, the corresponding HAFM Product Manager application is invoked.
product name
User-configurable identifier assigned to a managed product. Typically, this name is stored on
the product itself. A Director or Switch product name can also be accessed by a simple
network management protocol (SNMP) manager as the system name.
prohibited port connection
In a Director or Switch, in S/390 operating mode, an attribute that removes dynamic
connectivity capability.
proprietary
Privately owned and controlled. In the computer industry, proprietary is the opposite of open.
A proprietary design or technique is one that is owned by a company. It also implies that the
company has not divulged specifications that would allow other companies to duplicate the
product. Increasingly, proprietary architectures are seen as a disadvantage. Consumers prefer
open and standardized architectures, which allow them to mix and match products from
different manufacturers.
protective plug
In a fiber-optic environment, a type of duplex connector (or cover) that provides physical
protection (D). Contrast with loopback plug.
protocol
(1) Set of semantic and syntactic rules that determines the behavior of functional units in
achieving communication. (2) In systems network architecture, the meanings of and
sequencing rules for requests and responses for managing the network, transferring data, and
synchronizing network component states. (3) A specification for the format and relative timing
of data exchanged between communicating devices (D, I).
