NonStop System Glossary

node number
A number used to identify a member system in a network. The node number is usually unique for
each system in the network. See also node, ServerNet node number.
node routing ID
See ServerNet node routing ID.
node-numbering agent (NNA)
A field-programmable gate array (FPGA) in a single-mode fiber-optic (SMF) plug-in card (PIC) that
translates the node number of each ServerNet packet entering or exiting the external ServerNet
fabrics.
node-numbering agent (NNA) plug-in card (PIC)
A plug-in card (PIC) for the modular ServerNet expansion board (MSEB) that supports the
node-numbering agent (NNA) interface.
noft utility
A utility that reads and displays information from TNS/R native object files. See also enoft utility.
noncanonical input mode
For an Open System Services (OSS) process, a terminal input mode in which data is made available
to the process when a timer expires or when a certain number of characters have been entered.
Noncanonical data is not grouped into logical lines of input. This mode is sometimes called block
mode or transparent mode. Contrast with canonical input mode.
nonclustered
Lacking the quality of belonging to a cluster.
nonconfigured object
An object that comes into existence after Subsystem Control Facility (SCF) is running and that was
created in response to activity outside the SCF environment. An SCF STATUS command can display
the name of a nonconfigured object, but its state is UNKNOWN.
nondedicated (public) LAN
A local area network (LAN) connected to the Ethernet ports on an Ethernet 4 ServerNet adapter
(E4SA), Fast Ethernet ServerNet adapter (FESA), or Gigabit Ethernet ServerNet adapter (GESA).
Unlike a dedicated service LAN, a public LAN supports the connection of many types of servers
and workstations. System consoles can be connected to a public LAN, but such system consoles
cannot use all the client applications for OSM or TSM. See also dedicated service LAN.
nonessential firmware
Code that is used for support routines such as self-test diagnostics and that can be overwritten
during flash programming without affecting the next power-up operation. Contrast with essential
firmware.
nonexact point
A code location within an accelerated object file that is between memory-exact points. The mapping
between the TNS program counter and corresponding RISC instructions is only approximate at
nonexact points, and interim changes to memory might have been completed out of order.
