HP NonStop G-Series - Manual (Page 273)

A connector board that plugs into the backplane to allow one or more ServerNet cables to
exit the rear of the enclosure. The ServerNet expansion boards (SEBs) and 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. SEBs are
customer-replaceable units (CRUs) .
ServerNet router
An application-specific integrated circuit (ASIC) responsible for providing
interconnection of ServerNet links in a
ServerNet system area network (ServerNet SAN) .
A ServerNet router is never an end device.
ServerNet Switch Board
The component in a processor switch that provides the switching logic. The board has a
front panel with a liquid-crystal display (LCD) for operator and maintenance functions.
ServerNet system area network (ServerNet SAN)
A low-cost, high-speed network, contained within a system, that connects processors to
each other and to ServerNet addressable controllers (SACs).
See also local area network (LAN) and wide area network (WAN) .
ServerNet wide area network (SWAN) concentrator
(1) An HP data communications peripheral that provides connectivity to an HP NonStop
server. The SWAN concentrator supports both synchronous and asynchronous data over
RS-232, RS-449, X.21, and V.35 electrical and physical interfaces. (2) A collective term
for both SWAN concentrators and SWAN 2 concentrators when a distinction between the
two is not required.
ServerNet wide area network (SWAN) 2 concentrator
An HP data communications peripheral that provides connectivity to an HP NonStop
server. The SWAN 2 concentrator supports both synchronous and asynchronous data
over RS-232, RS-449, X.21, and V.35 electrical and physical interfaces. The SWAN 2
concentrator is the next-generation SWAN concentrator and has 12 WAN ports.
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.
