Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP). An asynchronous request-response
protocol used for network management. SNMP originated as a means for managing
Transmission Control Protocol/Internet Protocol (TCP/IP) and Ethernet networks.
OSM and TSM packages can include an SNMP-compliant interface for communication
between the system console and HP NonStop™ S-series server.
single-high ServerNet adapter. A ServerNet adapter that occupies only the upper half of a
ServerNet adapter slot in an HP NonStop™ S-series server. Contrast with double-high
ServerNet adapter.
single-high stack. A stack that includes a base, a frame, and one system enclosure.
Contrast with double-high stack.
single-mode fiber-optic (SMF) plug-in card (PIC). A plug-in card (PIC) for the modular
ServerNet expansion board (MSEB) and I/O multifunction (IOMF) 2 customer-
replaceable unit (CRU) that supports the single-mode fiber-optic (SMF) interface.
single-mode fiber-optic (SMF) ServerNet cable. A fiber-optic cable that allows only one
mode to propagate. SMF ServerNet cable has a small-diameter core for optimized
long-distance transmission. See also multimode fiber-optic (MMF) ServerNet cable.
single-wide plug-in card (PIC). A small-form-factor plug-in card (PIC) that occupies one
PIC slot within a customer-replaceable unit (CRU). See also double-wide plug-in card
(PIC).
sinusoidal. A waveform that can be mathematically expressed by the sine function.
SIT. See system image tape (SIT).
site update tape (SUT). One or more tapes that contain each target system’s site-specific
subvolume and various products. Each product contains a softdoc and a complete set
of files. A SUT is delivered with every new HP NonStop™ S-series system and can be
ordered whenever a new release version update (RVU) of the system software is
available. A full SUT contains the current RVU of the HP NonStop Kernel operating
system and all product software that has been ordered with it. A partial SUT contains
a subset of products for the current software RVU.
SIV. See system interrupt vector (SIV).
skin effect. The tendency of higher frequency signals to flow on the outside surface, or
skin, of a conductor instead of through the entire cross-section of the conductor. The
result is less total conductor area available for carrying current and an increase in the
resistance of the conductor at that high signal frequency.
slot. A physical, labeled space for a customer-replaceable unit (CRU) or field-replaceable
unit (FRU) that is part of a module. A module contains one or more slots.
