single-mode fiber-optic (SMF) plug-in card (PIC)
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 operating system
and all product software that has been ordered with it. A partial SUT contains a subset
of products for the current 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.
slot location. A three-number identifier for a particular slot on a system that consists of the
group number, module number, and slot number; for example, 02,01,08 (group 02,
module 01, slot 08).
SLSA subsystem. See ServerNet LAN Systems Access (SLSA) subsystem.
small computer system interface (SCSI). An ANSI-standard protocol used by a controller
to access a device.
SMB. See serial maintenance bus (SMB).
SMB domain. See serial maintenance bus (SMB) domain.
SMF. See storage pool.
