FEDERAL COMMUNICATIONS COMMISSION
AND
CANADIAN DEPARTMENT OF COMMUNICATIONS
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate 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 communication. It has been tested and
found to comply with the limits for a Class A computing device in accordance with the
specifications in Subpart B of Part 15 of FCC rules, which are designed to provide
reasonable protection against such interference when the equipment is operated in a
commercial environment. Operation of this equipment in a residential area is likely to
cause interference, in which case the user at his own expense will be required to take
whatever measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

Certification Notice for
Equipment Used in Canada
The Canadian Department of Communications label identifies certified equipment. This
certification means that the equipment meets certain telecommunications-network
protective, operation, and safety requirements. The Department does not guarantee the
equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment
must also be installed using an acceptable method of connection. In some cases, the
company’s inside wiring associated with a single-line individual service may be extended
by means of a certified connector assembly (extension cord). The customer should be
aware that compliance with the above conditions may not prevent degradation of service
in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance
facility—in this case, your supplier. Any repairs or alterations made by the user to this

equipment, or equipment malfunctions, may give the telecommunications company cause
to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the
power utility, telephone lines, and internal metallic water pipe system, if present, are
connected together. This precaution may be particularly important in rural areas.
CAUTION:
Users should not attempt to make such
connections themselves, but should contact
the appropriate electric inspection authority,
or electrician, as appropriate.
The LOAD NUMBER (LN) assigned to each terminal device denotes the percentage of
the total load to be connected to a telephone loop which is used by the device, to prevent
overloading. The termination on a loop may consist of any combination of devices,
subject only to the requirement that the total of the load numbers of all the devices does
not exceed 100.

Port Connectors:
Two RJ-45 Ports: support 100BASE-TX and 10BASE-T with auto-cross (MDIX).
They are shielded 8-pin female connectors for shielded (STP) and unshielded
(UTP) Cat 3, 4, 5 copper twisted-pair cable.
One Fiber optic port: On the LBH110 series, it is 10Base-FL with ST connector.
On the LBH100 series, it is 100Base-FX with a “fiber flavor” choice of multimode
SC, ST or MTRJ or single-mode SSC, SSCL, SST or SLC connectors.
For Power over Ethernet (POE) pass-through option on the RJ-45 connectors of
the H and P models, request quote.
Switches
The Fiber Port is controlled by an “F – H” switch, provided underneath it.
“F” enables full-duplex mode and “H” enables half-duplex mode.
The default setting is “F” for 100Mb fiber models, “H” for 10 Mb fiber models.
