MULTI-RATE 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 Multi-Rate Ethernet Extender generates and uses radio frequency energy,
and if not installed and used properly-that is, in strict accordance with the manu­facturer’s instructions-may cause interference to radio and television reception.
The Multi-Rate Ethernet Extender has been tested and found to comply with the
limits for a Class A computing device in accordance with specifications in Sub­part B of Part 15 of FCC rules, which are designed to provide reasonable protec­tion from such interference in a commercial installation. However, there is no
guarantee that interference will not occur in a particular installation. If the Ether­net 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 comput­ing 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).

• 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 uti­lized to power the device shall be within 10 feet (3

WARNING

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 Multi-Rate Ethernet Extender/L (Local) and Multi-Rate Ethernet Extender/R
(Remote) provide high speed LAN connections between peered Ethernet LANs,
remote PC’s, or any other network enabled 10/100Base-T device.

Operating in pairs, a Multi-Rate Ethernet Extender/L (Local) located at one end
of the LAN extension and a Multi-Rate Ethernet Extender/R (Remote) at the
other end, these units can automatically forward LAN broadcasts, multicasts, and
frames across a 2-wire voice-grade twisted-pair link. The data is passed transpar-

MULTI-RATE ETHERNET EXTENDER

ently (unmodified) through the Multi-Rate Ethernet Extenders. The Ethernet
Extenders automatically add and delete MAC addresses, only passing packets
across the link that are meant for the remote peered LAN.

Figure 1.

Typical application

The Local and Remote Multi-Rate Ethernet Extenders work together to create a
transparent extension between two peered Ethernet LANs. Figure 1 shows a typi­cal point-to-point application.
