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

BLACK BOX®Gigabit Media Converter Switch Installation & User Guide

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.
