ECC
steel, and ground rods into the earth) and bonding them to the switchgear at the
facility’s main electrical service entrance.
ECC. See error correction code (ECC).
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.
electromagnetic interference (EMI). Forms of conducted or radiated interference that
might appear in a facility as either normal or common-mode signals. The frequency of
the interference can range from the kilohertz to gigahertz range. However, the most
troublesome interference signals are usually found in the kilohertz to low megahertz
range. At present, the terms electromagnetic interference and radio frequency
interference (RFI) are usually used interchangeably.
electrostatically shielded transformer. A transformer that has a metallic shield placed
between the primary and secondary windings. This shield diverts high-frequency
signals to ground.
electrostatic discharge (ESD) protection kit. A kit containing an antistatic mat and a
wriststrap with a cable and grounding clip. A service provider or customer wears the
wriststrap while performing maintenance procedures inside an enclosure. The
wriststrap and cable contain grounding wires. When the grounding clip is attached to a
