Dynamic System Configuration (DSC)
Dynamic System Configuration (DSC). A utility used in D-series and earlier release
version updates (RVUs) to make online changes to the configuration of devices and
controllers. Its interactive utility is called the Configuration Utility Program (COUP). In
G-series RVUs, similar functions are performed by Subsystem Control Facility (SCF).
E4SA. See Ethernet 4 ServerNet adapter (E4SA).
earth ground. The connection of the electrical-grounding conductors to a dependable, low-
resistance contact with the soil.
earth-grounding electrode. An electrically conductive rod that is driven into soil, thus
providing an earth-ground connection point for the electrical ground wiring in a building.
A vertical steel column of a building, with its base sunk into soil, can also serve as an
earth-grounding electrode.
earth-grounding electrode system. A grounding network created by bonding together the
grounding means in a building (for example, underground metal water pipes, structural
steel, and ground rods into the earth) and bonding them to the switchgear at the
facility’s main electrical service entrance.
ECL. See emitter-coupled logic (ECL).
ECL plug-in card (PIC). See emitter-coupled logic (ECL) plug-in card (PIC).
ECL ServerNet cable. See emitter-coupled logic (ECL) ServerNet cable.
EDIT file. In the Guardian file system, an unstructured file with file code 101. An EDIT file
can be processed by either the EDIT or PS Text Edit (TEDIT) editor. An EDIT file
typically contains source program or script code, documentation, or program output.
Open System Services (OSS) functions can open an EDIT file only for reading.
effective group ID. An attribute of an Open System Services (OSS) process that is used to
determine permissions such as the file access allowed for the process. The effective
group ID of a process is a group ID that contributes to the group access privileges of
that process. The effective group ID of a process might be used to set the group ID of
files created by that process. The effective group ID can be changed while the process
runs.
effective user ID. An attribute of an Open System Services (OSS) process that is used to
determine such permissions as the file access allowed for the process. The effective
user ID of a process is the user ID that determines the owner access privileges of that
process. The effective user ID of a process might be used to set the user ID of files
created by that process. The effective user ID can be changed while the process runs.
EIA. Electronic Industries Association.
electric utility. The local utility service that, for a fee, supplies alternating-current (AC)
power to businesses and residences.
