ServerNet expansion board (SEB)
ServerNet expansion board (SEB). (1) A connector board that plugs in to the backplane to
allow one or more ServerNet cables to exit the rear of the enclosure. The SEBs and
ServerNet cables allow processors in one group to communicate with processors in
another group. Each SEB provides either the ServerNet X fabric or the ServerNet Y
fabric for a group. (2) A collective term for both SEBs and modular SEBs (MSEBs)
when a distinction between the two types of SEBs is not required.
ServerNet/FX adapter. A ServerNet adapter that logically extends the ServerNet X and Y
fabrics to other clusters in a Fiber Optic Extension (FOX) ring by using fiber-optic lines.
Two 6740 ServerNet/FX adapters are used, one for the X ring and one for the Y ring.
ServerNet/FX 2 adapter. A ServerNet adapter that logically extends the ServerNet X and Y
fabrics to other clusters in a Fiber Optic Extension (FOX) ring by using fiber-optic lines.
Two 6742 ServerNet/FX 2 adapters are used, one for the X ring and one for the Y ring.
ServerNet LAN Systems Access (SLSA) subsystem. A subsystem of the HP NonStop™
operating system for configuration and management of ServerNet local area network
(LAN) objects in G-series release version updates (RVUs).
ServerNet wide area network (SWAN) concentrator. An HP data communications
peripheral that provides connectivity to a NonStop S-series server. The SWAN
concentrator supports both synchronous and asynchronous data over RS-232,
RS-449, X.21, and V.35 electrical and physical interfaces.
service connection. A connection between the TSM client software running on a system
console and the TSM server software running on an HP NonStop S-series server. A
service connection can be used only to communicate with the server when the HP
NonStop operating system is running. A service connection provides a comprehensive
service and maintenance picture of the server and is used to perform most service
management tasks. See also low-level link.
service processor (SP). A physical component of the processor multifunction (PMF)
customer-replaceable unit (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 Mission Critical Solution Center
(GMCSC), that helps you resolve problems with your NonStop S-series server. The
TSM package allows you to use the help of a service provider by configuring TSM to
support remote notification and remote access.
