built configuration
built configuration. A configuration revision for which a system image and activation
package have been created.
built-in command. In the Open System Services (OSS) environment, a command that is
implemented within the /bin/sh file. Some built-in commands are also available as
separately executable files.
bypass mechanism. Equipment that permits switching from one power source to another.
For example, a bypass mechanism on an uninterruptible power supply (UPS) would
switch to an alternative power source (such as a standby power generator or
commercial utility source) when maintenance must be performed on the UPS.
byte-synchronous. A type of Open Systems Interconnection (OSI) Layer-2 protocol that
uses synchronous transmission techniques and requires a character code to define
terminal and line control sequences. Data is always transmitted in a block.
cabinet. The rack, front and back doors, side panels (if any), and PDUs. Cabinets contain
enclosures and other system components. A cabinet that can contain multiple
enclosures is also called a modular system.
cable channel. A cable management conduit that protects the cables that run between two
HP NonStop™ S-series system enclosures in a double-high stack. Each system
enclosure has two cable channels running vertically on its service side: one on the
left-hand side of the enclosure, and one on the right-hand side of the enclosure.
cable guidepost. A cable management rod that routes cables exiting an HP NonStop™
S-series upper enclosure in a double-high stack to prevent the cables from hanging
down in front of the customer-replaceable units (CRUs) in the base enclosure. A cable
guidepost extends from the base of each cable channel.
cable support. A piece of cable management hardware that secures system cables. The
cable support attaches to the service side of a system enclosure near the bottom of the
enclosure. Cable ties for securing system cables are threaded through the cable
support. The cable support also contains the group and module ID labels and the rear
group service light-emitting diode (LED).
cache. See cache memory.
cache memory. Small, fast memory holding recently accessed data designed to speed up
subsequent access to the same data. Cache memory is built from faster memory chips
than main memory, and it is most often used with processor main memory as well as
network data transfer to maintain a local copy of data. Contrast with main memory.
cached bindings. A copy in virtual memory of the data pages containing symbolic
references that were rebound when a loadfile was loaded. The cached bindings are
associated with a library import characterization that characterizes the set of loadfiles
to which the symbols were bound. If the same file is subsequently loaded in an
equivalent environment in the same processor, the cached bindings can be reused.
