HIGH SPEED ETHERNET EXTENDER

CE NOTICE

The CE symbol on your Black Box equipment indicates that it is in compliance

with the Electromagnetic Compatibility (EMC) directive and the Low Voltage

Directive (LVD) of the European Union (EU). A Certiﬁcate of Compliance is

available by contacting Technical Support.

RADIO AND TV INTERFERENCE

The High Speed Ethernet Extender generates and uses radio frequency energy,

and if not installed and used properly-that is, in strict accordance with the manu-

facturer’s instructions-may cause interference to radio and television reception.

The High Speed Ethernet Extender has been tested and found to comply with the

limits for a Class A computing device in accordance with speciﬁcations in Sub-

part B of Part 15 of FCC rules, which are designed to provide reasonable protec-

tion from such interference in a commercial installation. However, there is no

guarantee that interference will not occur in a particular installation. If the Ether-

net Extender does cause interference to radio or television reception, which can

be determined by disconnecting the unit, the user is encouraged to try to correct

the interference by one or more of the following measures: moving the comput-

ing equipment away from the receiver, re-orienting the receiving antenna and/or

plugging the receiving equipment into a different AC outlet (such that the com-

puting equipment and receiver are on different branches).

WARNING

Theis device is NOT intended nor approved to be con-

nected to the PSTN. It is intended only for connection to

customer premise equipment.

WARNING

• This device contains no user serviceable parts. The

equipment shall be returned to Black Box for repairs, or

repaired by qualiﬁed service personnel.

• The external power adapter should be a listed Limited

Power Source. Ensure that the power cable used meets

all applicable standards for the country in which it is to

be installed, and that it is connected to a wall outlet

which has earth ground. The mains outlet that is uti-

lized to power the device shall be within 10 feet (3

meters) of the device, shall be easily accessible, and

protected by a circuit breaker.

• Do not work on the system or connect or disconnect

cables during periods of lightning activity.

1.2 Description

The Black Box LB400A Ethernet Extenders provide high-speed LAN connec-

tions between peered Ethernet LANs, remote PC’s, or any other network enabled

10/100Base-T devices.

Operating in pairs, one LB400A is conﬁgured as the (L) Local unit located at one

end of the LAN extension and the other LB400A is conﬁgured as the (R) Remote

unit at the other end. The LB400A is conﬁgured as a L or R via the switch on the

rear panel. These units can automatically forward LAN broadcasts, multicasts,

and frames across a 2-wire voice-grade twisted-pair link. The data is passed

transparently (unmodiﬁed) through the high speed ethernet extenders. The

LB400A automatically adds and deletes MAC addresses, only passing packets

across the line that is meant for the remote peered LAN.

Figure 1.

Typical application

The pair of LB400A models work together to create a transparent extension

between two peered Ethernet LANs. Figure 1 shows a typical point-to-point

application.

2. Installation

2.1 Installing the High Speed Ethernet Extender

Do the following:

1. Connect the line interface between the units (refer to section 2.2, “Connect-

ing the Twisted-Pair Line Interface” on page 10)

Note

See Figure 2 for the standalone unit’s rear panel arrangements.

2. Connect the Ethernet interface (refer to section 2.3, “Connecting the

10/100Base-T Ethernet Interface” on page 11).

3. Connect the power plug (refer to section 2.4, “Connecting Power” on

page 12).

CAUTION

The Interconnecting cables shall be acceptable for

external use and shall be rated for the proper applica-

tion with respect to voltage, current, anticipated tem-

perature, ﬂammability, and mechanical serviceability.

2.2 Connecting the Twisted-Pair Line Interface

The High Speed Ethernet Extender supports communication between two peer

Ethernet LAN sites over a distance of up to 6,000 ft (1.83 km) over 24 AWG

(0.5 mm) twisted-pair wire.

Note

Actual distance and link performance may vary depending on the envi-

ronment and type/gauge of wire used.

Follow the steps below to connect the High Speed Ethernet Extender interfaces.

Note

The LB400A works in pairs. One of the units must be a L (Local), and

the other unit must be a R (Remote). It does not matter which end is the L

and which is the R. The link is always initiated by the Remote.As long as

the Local is powered on, the Remote can establish a link by being pow-

ered on or by having its power reset.

1. To function properly, the two LB400As 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 equip-

ment are not acceptable.

2. The LB400A is equipped with an RJ-45 interface jack that to be used for

the LINE interface. This LINE interface is a two-wire interface. Observe

the signal/pin relationships on the LB400A’s LINE jack.

The RJ-45 connector on the LB400A's twisted pair interface is polarity insensi-

tive and is wired for a two-wire interface. The signal/pin relationship is shown in

Figure 3.
