Express Ethernet Switches

These well-engineered machines provide dedicated high-speed

workgroups, plus they improve network performance and keep data
moving freely and quickly.

Express Ethernet Switches

enable you to put a full wire-speed

switch right into a network without making a large investment. Plus
they’re available in a wide variety of port options, from a 2-port model
for small network extension to a 24-port switch with optional fiber
uplink for mid-sized networks.

Each switch provides true Layer 2 nonblocking switch architecture

and a store-and-forward switching engine. With Layer 2 switching,
you get the speed to handle lots of network data. The store-and-
forward engine checks the integrity of each data packet and ensures
accurate throughput.

All

Express Ethernet Switches

have an autosensing power supply

that adapts to worldwide voltages. A crossover switch makes
uplinking to other switches or hubs easy. Extensive LEDs provide
port status.

All RJ-45 ports operate at 10/100 Mbps in half- or full-duplex

mode. The fiber ports are for 100-Mbps connections in either half-
or full-duplex mode.
10-/100-Mbps Copper (LB9108A-R2, LB9019A-R4, LB9020A-R3)

These switches feature 8, 16, or 24 autosensing 10-/100-Mbps

RJ-45 ports. They’re perfect for rapid, inexpensive network expansion
or building workgroups. The autosensing ports adjust to the speed
and duplexity of each port automatically. All ports have auto MDI/
MDI-X.

The 8-port model supports 16,384 MAC address entries to

support large numbers of end users. It’s housed in a compact,
sturdy enclosure suitable for desktop use or wallmounting.

OVERVIEW

The 16- and 24-port switches support 2048 MAC addresses

with address filtering on all ports.
2-Port Express Ethernet Switches, Copper and Fiber
(LB9002A-SC-R3, LB9002A-ST-R3)

These compact 2-port switches divide a network into a

10-/100-Mbps copper segment and a 100-Mbps fiber segment.

The 2-port switches are ideal for adding a 100-Mbps fiber island

to your existing network or for extending a network long distances
over fiber optic cable. To handle the heavy traffic load associated with
this sort of network link, the 2-port switches support 8192 MAC
address entries.

Choose from ST

or SC connectors on the 100BASE-FX side.

Each switch features automatic MDI-X for linking to another device.
The switches can be wallmounted or used on the desktop.
5-Port Express Ethernet Switch (LB9005A-FO-R2)

This compact copper plus fiber 5-port switch is ideal for adding

small workgroups to your network. The single fiber port serves as an
uplink to your network. Four 10/100 autosensing copper ports feature
auto MDI/ MDI-X, making it easy to connect workstations without
fuss. The switch supports 2048 MAC addresses.

The compact chassis is only about six inches wide so you can

tuck it in behind a PC. You may also mount it on any horizontal
or flat surface.
8-Port Express Ethernet Switches
(LB9006A-SC, LB9006A-ST, LB9021A–LB9022A, LB9007A-SC-R3,
LB9007A-ST-R3)

The 8-port switches are good for integrating 100-Mbps fiber into

your existing 10-/100-Mbps network. The extra distance from fiber
means you can extend network segments up to 1.2 miles (1.9 km).
The switches support 1024 MAC address entries.
