OVERVIEW

High-speed switching technology at an affordable cost—get the

best of both worlds with BL ACK BOX

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-and­forward 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.

Workstations

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
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.

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 Port­Trunking groups. The LB9007A-R3 models also feature auto MDI/
MDI-X.

The LB9006A-SC, LB9006A-ST, LB9021A, and LB9022A models
can be rackmounted (hardware is included). The LB9007A-R3 models
are intended for desktop use; if you wish to rackmount them, contact
Tech Support for the appropriate hardware.

10-/100-Mbps Copper, 100-Mbps Fiber, Modular (LB9017A-R4,
LB9024A-R2) and Optional Fiber Uplink Modules (LB9017C-SC-R2,
LB9007C-ST-R2)

These Express Ethernet Switches feature 16 or 24 auto-sensing
10-/100-Mbps RJ-45 ports. They’re an economical way to quickly
expand your 10BASE-T/100BASE-TX network with the option of
adding a fiber uplink later if you need it.

Although the switches are easy to set up, they offer powerful
features to help you control heavy network loads. The 2048 MAC
address table handles a large number of end users.

These modular switches also include an RS-232 RJ-45 console
port for basic management (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 VL AN and Port­Trunking configuration groups. Remote configuration via the network
is also possible.

Trunking provides extra bandwidth of up to 400 Mbps between
two connected switches. You can also regulate standard backpressure
and autonegotiation on individual ports. The crossover button enables
you to configure one port as an uplink. These switches occupy only
1U of rack space and are easily rackmountable with the included
hardware.

100-Mbps Fiber Express Ethernet Switch
(LB9008A-FO-R2)

For simplicity, speed, and distance, choose this fiber-only switch.
It provides eight ports of blazing speed and distances of up to 1.2 miles
(1.9 km) with all the security of fiber. Best of all, this entry-level switch
is simple to set up — just plug-and-play.

The switch has SC-style fiber connectors and supports 1024 MAC
address entries. It has DIP switches and is easy to rack-mount with
the included hardware.

Modular Express Ethernet Switch (LB9217A-R2) and
Modules (LB9213A–LB9216A, LB9218A–LB9219A, LB9220C-ST-R2,
LB9220C-SC-R2)

For the rapidly changing and growing network, the 2
Modular Express Ethernet Switch offers an affordable modular
solution that enables you to customize your switch with any
combination of copper and fiber ports as well as fiber uplinks.

The switch has two slots that you can fill with 8-port modules in
combinations of 100-Mbps multimode fiber ports or 10/100 RJ-45
copper ports. A third “half” slot is reserved for a 1-port fiber uplink
module.

The switch supports several “smart” features such as port-based
VLAN and MAC-based trunking.

The 10/100 copper ports are autosensing for speed and duplex,
and they support auto MDI/MDI-X. Speed and half- or full duplex can
be programmed as either fixed or auto negotiating. Fiber ports are all
100-Mbps Fast Ethernet and come in a choice of ST or SC connectors.

The switch is rackmountable, occupying only 1U of rack space in
a standard 19" rack. Rackmount ears are included.

Technically Speaking

Layer 2 switching.

A switch helps provide a clear path from each workstation
to its destination on demand, whether that destination is
another workstation or a server. In contrast with bridges and
routers (which process data packets on an individual, first­come, first-served basis), switches maintain multiple, simulta­neous data conversions among attached LAN segments.

From an end-user workstation’s perspective, a switched
circuit appears as a dedicated connection — a direct, full­speed LAN link to an attached server or other remote LAN
node. Although this technique is somewhat different from
what a LAN bridge or router does, switching hubs are based
on similar technologies.

Switching hubs that use bridging technologies are called
Layer 2 switches—a reference to Layer 2 or the Data Link
Layer of the OSI Model. These switches operate using the
MAC addresses in Layer 2 and are transparent to network
protocols. Layer 2 switches connect different parts of the
same network, as determined by the MAC address contained
in the packet. You can install a Layer 2 switch anywhere on
a network without reconfiguring the LAN.

they need is extremely important when choosing a vendor. But even
though network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support contract, the
technical support and service they receive falls far short of their
expectations—and certainly isn’t worth what they paid.
