VLAN
Virtual LAN. A logical association that allows users to
communicate as if they were physically connected to
a single LAN, independent of the actual physical
configuration of the network.
warm swapping
A feature that allows you to remove and replace a
power supply in the 7-slot chassis when the
Standby/On switch is in the Standby position or
remove and replace a power supply in the 8-slot
chassis or 16-slot chassis when the On/Off switch is in
the Off position, without disconnecting the AC input
power cord.
wiring closet
A central area that is used for wiring networking
systems and telephone communication systems.
10/100
Both 10 Mbps and 100 Mbps on the same port.
100BASE-FX
A 100BASE-FX Fast Ethernet Switching Module that
has ten 100 Mbps Ethernet fiber-optic front panel
ports. These ports interface to one 1-Gigabit
non-blocking port on the backplane. It is an
intelligent module that has its own embedded agent.
A 100BASE-FX (MMF-SC) Fast Ethernet Multiprotocol
Router Module that has ten 100 Mbps front-panel
external ports of full-duplex 100BASE-FX, using SC
(Subscriber Connector) connectors over MMF
(multi-mode fiber) and one Gigabit Ethernet (GEN)
port that connects to the backplane.
10/100BASE-TX
10/100BASE-TX Fast Ethernet Switching Modules that
have twenty or thirty-six 10/100 Mbps RJ-45 front
panel ports. These ports interface to a maximum of
two 1–Gigabit non-blocking ports on the backplane.
They are intelligent modules that have their own
embedded agent.
A 10/100BASE-TX Fast Ethernet Multiprotocol Router
Module that has twelve 10/100 Mbps RJ-45 front
panel ports. These ports interface to a maximum of
two 1–Gigabit non-blocking ports on the backplane.
It is an intelligent module that has its own embedded
agent.
1000BASE-SX
A Gigabit Ethernet (GEN) Interface Module that
serves as a 2–Gigabit data channel between the
Gigabit Ethernet Switch Fabric Module and other
802.3z–compliant Gigabit Ethernet devices. GEN
Interface Modules use SC connectors. Ports on this
module use an 850-nanometer, multimode, optical
transceiver.
1000BASE-LX
A Gigabit Ethernet (GEN) Interface Module that
serves as a 2–Gigabit data channel between the
Gigabit Ethernet Switch Fabric Module and other
802.3z–compliant Gigabit Ethernet devices. GEN
Interface Modules use SC connectors. Ports on this
module use an 1300-nanometer, multi/single-mode,
optical transceiver.
