SCI
Serial communication interface. An IEEE standard for
a high-speed bus that uses wire or fiber-optic cable.
server
A computer that provides clients with application and
network services. Servers are shared by multiple users.
SMC
System Management Component. The central
network management agent that provides central
network management operations within the Switch.
SNMP
Simple Network Management Protocol. A protocol
originally designed to be used in managing TCP/IP
internets.
SNMP is presently implemented on a wide variety of
computers and networking equipment and may be
used to manage many aspects of network and end
station operation.
spanning tree
A technique that detects loops in a network and
logically blocks the redundant paths, ensuring that
only one route exists between any two LANs; used in
an IEEE 802.1d bridged network.
star-wired
LAN topology in which end points on a network are
connected to a common central switch by
point-to-point links. A ring topology that is organized
as a star implements a unidirectional closed-loop star,
instead of point-to-point links.
switch fabric module
A central backplane aggregator for the Switch.
topology
The physical or logical placement of stations on a
network in relation to one another.
torque
The amount of force exerted to tighten a screw, bolt,
or nut.
traces
Links that are star-wired to the slot with the switch
fabric module, providing primary high-speed links for
each interface module.
trunk
Physical and logical connection between two switches
across which network traffic travels.
twisted pair
Two insulated wires that are wrapped around each
other for protection against interference. Each wire is
insulated, and the pair is usually covered by an overall
casing. This type of wiring is generally used for
connecting 10BASE-T, 100BASE-T, and FDDI systems.
UART
Universal asynchronous receiver/transmitter. A chip
that is used as communications (COM) port in
