and keep data moving freely and quickly.
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

10-/100-Mbps Copper (LB9108A-R2, LB9019A-R4,
LB9020A-R3)
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.

2-Port Express Ethernet Switches, Copper and Fiber
(LB9002A-SC-R3, LB9002A-ST-R3)
(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.

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 it tuck in behind a PC. You may also mount it on
any horizontal or flat surface.

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.

The LB9006A-SC, LB9006A-ST, LB9021A, and LB9022A
models provide DIP switches for controlling port operation
manually. For greater versatility, the LB9007A-R3 models
have a console port that enables you to control ports and
set up port-based VLANs and trunking.

Both LB9007A-R3 models support management.
The management type is an ASCII console port (cable
included) that provides access to a text-based menu.
The menu permits basic configuration of port parameters
(such as changing speed or duplex settings), and has a
proprietary method for assigning the ports into VLAN and
Port-Trunking groups. The LB9007A-R3 models also feature
auto MDI/MDI-X.
