Cluster switch zone – HP NonStop G-Series User Manual
Page 251
The topological cluster switch position within a
group can contain up to four layers, numbered 1 to 4 from bottom to top. A cluster switch
layer consists of a pair of cluster switches (X and Y) and provides connections for up to
eight ServerNet nodes. Layers within a group are interconnected by intragroup cables.
When all four layers are present, the intragroup cables are configured as a
cluster switch layer number
A number in the range 1 through 4 that identifies the position of a cluster switch within a
cluster switch group. See also
cluster switch logic board
A circuit board that provides switching logic for
HP NonStop ServerNet Switch (model
. The logic board (LB) has a front panel for operator and maintenance functions.
cluster switch zone
A pair of X-fabric and Y-fabric
and the ServerNet nodes connected
to them. Up to three zones are possible. The zones, if more than one, are interconnected
by interzone cables, with each
cabled separately from the other layers
cold load
A synonym for
or load (in the case of a single processor load).
Common Communication ServerNet adapter (CCSA)
A ServerNet adapter that provides a NonStop S-series integration platform for Signaling
System Number 7 (SS7) protocol communications.
communications line interface processor (CLIP)
The major programmable device within the ServerNet wide area network (SWAN)
concentrator, providing link-level protocol and a software interface to the host. The CLIP
stores and implements specific communications protocols.
connection
A logical link established between the OSM client software on the system console and
the OSM server software on a NonStop S-series server after a logon sequence has been
performed. There are two types of connections:
The OSM Service Connection connects to the server using a service connection. The
OSM Low-Level Link connects to the server using a low-level link.
connector
A receptacle to which a cable can be attached. Also called a
.
critical message
A message indicating that the application has encountered an error that must be corrected
