router
A device that connects two remote networks by
selectively forwarding messages between them. A
router differs from a bridge and a gateway in that it
selectively forwards information between the
networks. Routers can be implemented in pairs, or a
router may communicate directly with a computer.
RS-232 serial port
A port that changes the parallel arrangement of data
within computers to the serial (one after the other)
form used on data transmission links. This port can be
used for dedicated local management access.
SC connector
A fiber-optic cable connector that uses a push-pull
latching mechanism similar to common audio and
video cables. For bi-directional transmission, two fiber
cables and two SC connectors are generally used.
SCC
System Controller Component. Supports switch
monitoring, module inventory management, and
power management.
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 4007.
topology
The physical or logical placement of stations on a
network in relation to one another.
