SAFETY WHEN WORKING WITH ELECTRICITY
WARNING
• 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 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.

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.
WARNING
This device contains no user serviceable parts.
This device can only be repaired by qualified service personnel.
WARNING
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 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 chassis.

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 broadcasts, 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.
Page 8 724-746-5500 | blackbox.com
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
CAUTION
The Interconnecting cables shall be acceptable for external use and shall be rated for the proper application with respect to voltage, current, anticipated temperature, flammability, and mechanical serviceability.
To install the Ethernet Extender, do the following:
1. Connect the line interface between the units (refer to section 2.1, “Connecting the
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).

Installation
2.1 CONNECTING THE LINE INTERFACE
CAUTION
The Interconnecting cables shall be acceptable for external use and shall be rated for the proper application with respect to voltage, current, anticipated temperature, flammability, and mechanical serviceability.
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 insensitive and is wired for a two-wire interface. The signal/pin relationship is shown in
Figure 3..

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
CAUTION
The Interconnecting cables shall be acceptable for external use and shall be rated for the proper application with respect to voltage, current, anticipated temperature, flammability, and mechanical serviceability.
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.

2.3 CONNECTING POWER
CAUTION
The Interconnecting cables shall be acceptable for external use and shall be rated for the proper application with respect to voltage, current, anticipated temperature, flammability, and mechanical serviceability.
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 necessary 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 minimum. Center pin is +12V. The barrel type plug has a 2.5/5.5/10mm I.D./O.D./Shaft
Length dimensions.
