SAFETY WHEN WORKING WITH ELECTRICITY
• This device contains no user serviceable parts. This
device can only be repaired by qualified service personnel.
WARNING
• 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 regulatory 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.
Page 6
• 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 hazardous 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
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 collection 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.
WARNING
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 prevent 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 chassis.

• Auto-MDIX Ethernet
• Configurable 10/100, Full/Half, and Auto-Negotiating Ethernet
• Extends up to 4x 10/100Base-TX Ethernet beyond 328-foot (100-meter) limitation over a single twisted-pair, Cat 5e/6/7, or coaxial cable
• Symmetric or asymmetric settings via DIP switch

• LED indicators for Power, DSL Link, Ethernet Link/Activity, Remote and Local
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 th e L A N e xte ns ion an d t he other Ethernet Extend er i s co nfi gure d a s 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 packets across the line link that are meant for the remote peered LAN.

The Interconnecting cables shall be acceptable
for external use and shall be rated for the
proper application with respect to voltage, cur-
CAUTION
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
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.

mm) twisted-pair wire,
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 sign al/pin relat ionsh ips on the Ether net Exten der's line interfac e
jack.
The RJ-45 conne ctor on the Ethernet Extende r's twi sted p air interfac e is p olarity inse nsitive and is wired for a two-wire interface. The signal/pin relationship is shown in

Once the Ethernet Extenders are properly installed, they should operate transparently.
No user settings required. This section describes reading the LED status monitors.
Before applying power to the Ethernet Extender, please review section 2.3, “Connecting Power” on page 13 to verify that the unit is connected to the appropriate power
source.
