High-speed switching technology at an affordable cost—
get the best of both worlds with BLACK BOX ® Express Ethernet
These well-engineered machines provide dedicated highspeed 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,
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.
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
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.
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
Port-Trunking 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 autosensing 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

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 VLAN and
Port-Trunking 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
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 rackmount with the included hardware.

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, full-speed
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.
For the rapidly changing and growing network, the 21⁄2-port
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 portbased 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 autonegotiating. 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.

Why Buy From Black Box?
Exceptional Value. Exceptional
Tech Support. Period.
Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives you
the wrong answer.
• You don’t have a purchase order number and the
tech refuses to help you.
• It’s 9 p. m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communications
magazine, 90% of network managers surveyed say
that getting the technical support 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.
At Black Box, we guarantee the best value and the
best support. You can even consult our Technical Support
Experts before you buy if you need help selecting just
the right component for your application.
Don’t waste time and money— call Black Box today.
