node number
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 and ServerNet node
number.
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.
node routing ID. See ServerNet node routing ID.
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 OSM or TSM client applications. 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. Breakpoints cannot be applied at
nonexact points. Contrast with memory-exact point and register-exact point.
noninteractive mode. A mode of operation that usually involves a command file (an EDIT
file that contains a series of commands). Contrast with interactive mode.
nonlinear load. Electrical load for which the instantaneous current is not proportional to the
instantaneous voltage. Consequently, the local impedance varies with the voltage.
