ATM Address
ATM Address. Defined in the UNI specification as 3 formats, each having 20 bytes in length
including country, area and end-system identifiers.
ATM Management Process (AMP). The process provided as part of the ATM subsystem
that initializes the shared-memory interface, initializes the XIO subsystem, creates and
monitors the Signaling Manager Process, initializes and downloads the ATM adapter,
and provides configuration information to the ATM adapter.
ATM Subsystem Manager (ASM). The manager process for the ATM subsystem. The
process is provided as part of the ATM subsystem that creates and starts the ATM
subsystem objects and starts a backup process for the AMP.
attribute. (1) For the SCF, a characteristic of an entity. For example, two attributes of a
process might be its program file and its user ID. An attribute is sometimes called a
modifier. (2) In OSM and TSM client interfaces, a data item associated with a system
or cluster resource. All attributes can be viewed and some can be modified.
backup processor. A processor running the HP NonStop Kernel operating system that
communicates with the primary processor, allowing the processors to remain
independent. A component failure in one processor has no effect on any other
processor.
board. A frame on which computer circuitry is mounted.
BUS. Broadcast and Unknown Server: This server handles data sent by an LE client to the
broadcast MAC address (‘FFFFFFFFFFFF’), all multicast traffic, and initial unicast
frames which are sent by a LAN Emulation client.
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.
See fastLoad.
cell. See storage pool
cell header. ATM Layer protocol control information.
chassis. A single sheet-metal structure that houses one set of system components. In an
NonStop S-series server, a chassis is part of a system enclosure but can also be
mounted in any standard 19-inch rack.
Class-1 CRU. A customer-replaceable unit (CRU) that probably will not cause a partial or
total system outage if the documented replacement procedure is not followed correctly.
Customers replacing Class-1 CRUs are not required to have previous experience
replacing NonStop S-series CRUs. However, for some CRUs, customers must be able
to use the tools needed for the replacement procedure (which are common tools) and
must protect components from electrostatic discharge (ESD).
