ServerNet switch
ServerNet switch. A point-to-point networking device that connects ServerNet nodes to a
single fabric (X or Y) of the ServerNet communications network. The ServerNet switch
routes ServerNet packets between these nodes.
service processor (SP). A physical component of the processor multifunction (PMF) CRU
or I/O multifunction (IOMF) CRU that controls environmental and maintenance
functions (including system load functions) in the enclosure. SPs operate in pairs to
provide fault tolerance. The two SPs in group 01 are designated the master service
processors (MSPs). Other pairs of SPs within a system are called expansion service
processors (ESPs).
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your NonStop S-series server. The OSM package
allows you to use the help of a service provider by configuring the OSM package to
support remote notification and remote access.
service side. The side of a system enclosure in a NonStop S-series server that contains,
behind an optional door, processor multifunction (PMF) customer-replaceable units
(CRUs) or I/O multifunction (IOMF) CRUs, ServerNet expansion boards (SEBs),
modular SEBs (MSEBs), and ServerNet adapters; it is opposite the appearance side.
Cables are accessed from the service side. System enclosures are typically arranged
so that the service side is the least visible side. See also appearance side.
SID. See software product revision (SPR).
single-mode fiber-optic (SMF) cable. A fiber-optic cable that allows only one mode to
propagate. SMF cable has a small-diameter core for optimized long-distance
transmission. See also multimode fiber-optic (MMF) 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).
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 system and can be ordered whenever a
new RVU of the system software is available. A full SUT contains the current RVU of
the 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.
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 3-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).
