SAFETY WHEN WORKING WITH ELECTRICITY
• This device contains no user serviceable parts. This
device can only be repaired by qualified service personnel.
• Do not open the device when the power cord is connected.
For systems without a power switch and without an external
power adapter, line voltages are present within the device
when the power cord is connected.
• For devices with an external power adapter, the power
adapter shall be a listed Limited Power Source. The mains
outlet that is utilized to power the device shall be within 10
feet (3 meters) of the device, shall be easily accessible, and
protected by a circuit breaker in compliance with local regu-
latory requirements.
• For AC powered devices, ensure that the power cable
used meets all applicable standards for the country in
which it is to be installed.
• For AC powered devices which have 3 conductor power
plugs (L1, L2 & GND or Hot, Neutral & Safety/Protective
Ground), the wall outlet (or socket) must have an earth
ground.
• For DC powered devices, ensure that the interconnecting
cables are rated for proper voltage, current, anticipated
temperature, flammability, and mechanical serviceability.
• WAN, LAN & PSTN ports (connections) may have hazard-
ous voltages present regardless of whether the device is
powered ON or OFF. PSTN relates to interfaces such as
telephone lines, FXS, FXO, DSL, xDSL, T1, E1, ISDN, Voice,
etc. These are known as “hazardous network voltages” and
to avoid electric shock use caution when working near
these ports. When disconnecting cables for these ports,
detach the far end connection first.
• Do not work on the device or connect or disconnect
cables during periods of lightning activity.
WARNING

Safety When Working With Electricity
In accordance with the requirements of council
directive 2002/96/EC on Waste of Electrical and
Electronic Equipment (WEEE), ensure that at
end-of-life you separate this product from other
waste and scrap and deliver to the WEEE col-
lection system in your country for recycling.
This device contains no user serviceable parts.
This device can only be repaired by qualified
service personnel.
This device is NOT intended nor approved for
connection to the PSTN. It is intended only for
connection to customer premise equipment.
Electrostatic Discharge (ESD) can damage
equipment and impair electrical circuitry. It
occurs when electronic printed circuit cards are
improperly handled and can result in complete
or intermittent failures. Do the following to pre-
vent ESD:
• Always follow ESD prevention procedures
when removing and replacing cards.
• Wear an ESD-preventive wrist strap, ensuring
that it makes good skin contact. Connect the
clip to an unpainted surface of the chassis
frame to safely channel unwanted ESD voltages
to ground.
• To properly guard against ESD damage and
shocks, the wrist strap and cord must operate
effectively. If no wrist strap is available, ground
yourself by touching the metal part of the chas-
sis.

1.2 DESCRIPTION
The Black Box Ethernet Extenders provide high-speed LAN connections between
peered Ethernet LANs, remote PCs, or any other network-enabled 10/100Base-T
device.
Operating in pairs, one Ethernet Extender is configured as the (L) Local unit located at
one end of the LAN extension and the other Ethernet Extender is configured as the (R)
Remote unit at the other end. The Ethernet Extender is configured as a L or R via the
switch on the bottom of the unit. These units can automatically forward LAN broad-
casts, multicasts, and frames across a 2-wire voice-grade twisted-pair or BNC link.
The data is passed transparently (unmodified) through the Ethernet Extenders. The
Ethernet Extenders automatically add and delete MAC addresses, only passing pack-
ets across the line link that are meant for the remote peered LAN.

724-746-5500 | blackbox.com Page 9
Installation
Figure 1. Typical application
The pair of Ethernet Extender models work together to create a transparent extension
between two peered Ethernet LANs using twisted pair (2-wire), Cat5+, or 75-ohm
BNC. Figure 1. shows a typical point-to-point application.
2. INSTALLATION
To install the Ethernet Extender, do the following:
1. Connect the line interface between the units (refer to section 2.1, “Connecting the
Line Interface” on page 11)
NOTE: See Figure 2. for the Ethernet Extender’s rear panel arrangements.
2. Connect the Ethernet interface (refer to section 2.2, “Connecting the 10/100Base-
T Ethernet Interface” on page 12).
3. Connect the power plug (refer to section 2.3, “Connecting Power” on page 13).
The Interconnecting cables shall be acceptable
for external use and shall be rated for the
proper application with respect to voltage, cur-
rent, anticipated temperature, flammability, and
mechanical serviceability.

Installation
2.1 CONNECTING THE LINE INTERFACE
The Ethernet Extender supports communication between two peer Ethernet LAN sites
over a distance of up to 10,000 ft (3 km) over 24 AWG (0.5 mm) twisted-pair wire,
Cat5+, or 75-ohm BNC.
NOTE: Actual distance and link performance may vary depending on the environment
and type/gauge of wire used.
NOTE: The Ethernet Extender units work in pairs. One of the units must be configured
as a (L) Local unit, and the other unit must be configured as a (R) Remote unit.
Connecting the Line Interface for LB411A or LB410A
To function properly, the two Ethernet Extenders must be connected together using
twisted-pair, unconditioned, dry, metal wire, between 19 (0.9mm) and 26 AWG
(0.4mm). Leased circuits that run through signal equalization equipment are not
acceptable.
The Ethernet Extender is equipped with an RJ-45 interface jack (Figure 3.) or terminal
block (Figure 4.) that can be used on the line interface. The line interface is a two-wire
interface. Observe the signal/pin relationships on the Ethernet Extender's line interface
jack.
The RJ-45 connector on the Ethernet Extender's twisted pair interface is polarity insen-
sitive and is wired for a two-wire interface. The signal/pin relationship is shown in
Figure 3..
Figure 3. Ethernet Extender (RJ-45) twisted pair line interfac.
The Interconnecting cables shall be acceptable
for external use and shall be rated for the
proper application with respect to voltage, cur-
rent, anticipated temperature, flammability, and
mechanical serviceability.

Connecting the Line Interface for LBNC412A
To connect the line interface of the Model LBNC412A, simply use a coaxial cable with
a BNC connector at each end to connect the pair of Ethernet Extenders.
2.2 CONNECTING THE 10/100BASE-T ETHERNET INTERFACE
The RJ-45 ports labeled Ethernet are the Auto-MDIX10/100Base-T interface. These
ports are designed to connect directly to a 10/100Base-T device or network. Figure 5.
shows the signal/pin relationships on this interface. You may connect this port to a hub
or PC using a straight through or crossover cable that is up to 328 ft long.
The Interconnecting cables shall be acceptable
for external use and shall be rated for the
proper application with respect to voltage, cur-
rent, anticipated temperature, flammability, and
mechanical serviceability.

2.3 CONNECTING POWER
The Ethernet Extender does not have a power switch, so it powers up as soon as it is
plugged in.
An external AC or DC power supply is available separately. This connection is made
via the barrel jack on the rear panel of the Ethernet Extender. No configuration is nec-
essary for the power supply (See Appendix B for domestic and international power
supply and cord options).
DC power (supplied via the power supply jack to the Ethernet Extender) must meet the
following requirements; DC power supplied must be regulated 12VDC ±5%, 1.0A mini-
mum. Center pin is +12V. The barrel type plug has a 2.5/5.5/10mm I.D./O.D./Shaft
Length dimensions.
The Interconnecting cables shall be acceptable
for external use and shall be rated for the
proper application with respect to voltage, cur-
rent, anticipated temperature, flammability, and
mechanical serviceability.
