speed, 6-port ServerNet routers, 8b/9b encoding, and a 64-byte maximum packet size.
See also ServerNet II.
ServerNet II. The second-generation ServerNet network. ServerNet II architecture is
backward-compatible with ServerNet I architecture, and it features 125 (or 50)
megabytes/second speed, 12-port ServerNet routers, 8b/9b and 8b/10b (serializer
ready) encoding, and a 512-byte maximum packet size. See also ServerNet I.
ServerNet cable. A cable that conducts ServerNet signals.
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 among these nodes.
ServerNet II Switch. A 12-port network switch that provides the physical junction point to
enable an HP NonStop™ server to connect to a ServerNet cluster.
ServerNet switch board. Component in an IOAM. The ServerNet switch board provides
ServerNet connections to the I/O adapters in the IOAM. It also provides maintenance
functions for the modules in which they are installed.
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.
service equipment. The necessary equipment, usually consisting of circuit breakers and
their accessories, that is located near the entrance point of supply conductors. This
equipment constitutes the main control and cutoff means of the supply.
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 HP NonStop™ server. OSM allows you to
use the help of a service provider by configuring client software to support remote
notification and remote access.
service side. The rear side of a HP NonStop™ S-series system enclosure. It contains
processor multifunction (PMF) customer-replaceable units (CRUs) or I/O multifunction
(IOMF) CRUs, ServerNet expansion boards (SEBs) or modular SEBs (MSEBs), and
ServerNet adapters. All cables are accessed from the service side. Most service
actions are performed from the service side. Service side doors are supplied with later
