AC. See alternating current (AC).
accelerated mode. The operational environment in which Accelerator-generated RISC
instructions execute. See also TNS mode
and TNS/R native mode.
accelerated object code. The RISC instructions that result from processing a TNS object
file with the Accelerator program.
accelerated object file. The object file that results from processing a TNS object file with
the Accelerator program. An accelerated object file contains the original TNS object
code, the accelerated object code and related address map tables, and any binder and
symbol information from the original TNS object file.
Accelerator program. A program that processes a TNS object file and produces an
accelerated object file. Most TNS object code that has been accelerated runs faster on
TNS/R processors than TNS object code that has not been accelerated. The
Accelerator program (AXCEL) is run prior to running the accelerated linker, XLLINK.
access mode. The form of file access permitted for a user or process.
ACL. See automatic cartridge loader (ACL).
ACS. See automated cartridge subsystem (ACS).
action. An operation that can be performed on a selected resource.
activation. The operator action of putting software into use after the software has been
applied from the activation package to the target system.
activation package. A set of files containing product files, operator instructions, and
instructions for applying the software on the target system. It consists of a header file
containing the activation instructions and file attributes, multiple data files, Distributed
Systems Management/Software Configuration Manager (DSM/SCM) control
information, and Event Management Service (EMS) events.
AC transfer switch. A component of an HP NonStop™ Cluster Switch (model 6770) that
provides access to dual AC power sources and the ability to switch between the two
sources if one fails. The AC transfer switch draws power from its primary power source
as long as it is available. If the primary source fails, the AC transfer switch is switched
to draw power from the secondary power source.
adapter. See ServerNet adapter.
adapter cable. (1) A cable that connects components that have incompatible electrical
interfaces. (2) For the ServerNet wide area network (SWAN) concentrator, one of four
