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

vii

BLACK BOX® Power Over Ethernet Switch(PoE) Installation and User
Guide

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.

POWER SUPPLY

These products are intended to be supplied by a Listed, Direct Plug-In power unit, marked
“Class 2”, or a Listed ITE Power Supply, marked “LPS”, which has suitably rated output
voltage (i.e. 9vdc, 12vdc, 24vdc, 48vdc), and suitably rated output current (i.e. 100mA to
500mA).When connected to a 48 V centralized dc source, these products shall be provided
with a Listed 5 A DC fuse in the supply circuit.

AC POWER SUPPLY ( using an external power adapter):

(OPTIONAL) LP004A have an (8-15)VDC output with 6ft long cord and a 2.5mm center
+ve jack. The power supplies are temperature rated to match the PoE Switch ratings.

NOTE- An external power adaptor is optional, is not included with unit, and must be
ordered separately if desired for convenience such as bench-testing. It is only used for
powering the unit to act as a switch, and does not provide power to any PoE devices
attached for the application.
Temperature un-controlled Extreme Ratings (-40 to 75°C)
All models. Outdoor temperature rated. Unit takes -12vdc, 2Amps, 6 watts

DC POWER Input : built-in terminal block for +, -,
ground, -48V DC input (range of 36 to 60V DC). The

Direct DC power input floats. User may ground either “+”
or “-” if desired.

Power Consumption: 6 watts for the unit, up to 60 watts (30 to 40 typical) for attached
PoE devices. See Section 3.6.
Note 1: The optional 8-15V DC jack can be used for dual source DC input using an AC
adapter and the DC terminal block. Power supply protection is provided by internal diodes.

Port Connectors

Four 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 cable.
