serial copper 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 serial copper
interface.
serial maintenance bus (SMB)
A bus that connects service processors within an enclosure to each other and to the
customer-replaceable units (CRUs).
See also serial maintenance bus (SMB) domain and power domain.
serial maintenance bus (SMB) domain
The set of enclosures, modules, field-replaceable units (FRUs), and customer-replaceable
units (CRUs) connected by a common serial maintenance bus (SMB).

server
A computer system used as a standalone system or as a node in a network.
Server is a synonym for system.
ServerNet adapter
A customer-replaceable unit (CRU) that connects peripheral devices to the system
through a ServerNet bus interface.
ServerNet addressable controller (SAC)
A controller that is uniquely addressable within one or more ServerNet address domains
(SADs) through the node ID and address fields in a request packet. A SAC is typically
implemented on some portion of a processor multifunction (PMF) customer-replaceable
unit (CRU), an I/O multifunction (IOMF) CRU, or a ServerNet adapter.
ServerNet cluster
A network of servers connected using the ServerNet protocol and sharing a common
transport for interprocessor communication across and within a cluster. It offers fast
end-to-end communication without intermediate protocol stacks, achieving comparable
speeds for internal and external ServerNet communication.
See also cluster.
ServerNet II switch
A 12-port network switch that provides the physical junction point to enable an NonStop
S-series server to connect to a ServerNet cluster. The ServerNet II switch is a component
