Three fixed-port models are
available. Each has seven 10-/
100-Mbps RJ-45 ports and works
with 100BASE-FX fiberoptic cable.
The LB9030A also accommodates
one 100-Mbps multimode dual SC
port, and the LB9031A features
one 100-Mbps multimode dual ST
port. The LB9032A has one 100-

Use the RJ-45 ports on the
fixed-port switches for short-
distance networking between
offices, workgroups, and
buildings. Connect via the fiber
port for longer distances. The

If you need a more flexible
configuration, order the modular
switch (LBG1000A-R2). It has
2410-/100-Mbps ports and
two slots for Gigabit uplinks. Plus,
it takes up only 1U of rack space.

Software management is
easy, too. All fixed-port and
modular switches support 2K
MAC addresses for transferring
traffic across the network
efficiently. And they support
SNMP and RMON. Manage the
switches in-band across the
network using any Web browser.
Or manage them out-of-band via
the RS-232 console port.

Using the switches’ 802.3p
Priority Queuing, give different
priorities to different types of
traffic. Traffic management,
network segmentation, and
network security also improve,
thanks to 802.1Q Tagged VLAN
support. The switches support
IP multicast traffic and video
multicasting or broadcasting via
IGMP snooping and Multicast
Filtering. Plus, they handle switch-
to-switch trunking, port-mirroring,
and monitoring for traffic
snooping.

Wire-speed packet switching
and packet-forwarding are also
supported. 802.3x flow control and
backpressure prevent overflow of
data frames, for better traffic
management when the network is
congested. Front-panel LEDs
allow status checks for each port.
