STATEMENTS
FCC - CLASS A
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment
is operated in a commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the
interference at his own expense.
You are cautioned that changes or modificationsnot expressly approved by the
party responsible for compliance could void your authority to operate the
equipment.
You may use unshielded twisted-pair (UTP) for RJ-45 connections - Category 3
or better for 10 Mbps connections, Category 5 or better for 100 Mbps
connections, Category 5, 5e, or 6 for 1000 Mbps connections. For fiber optic
connections,
you may use 50/125 or 62.5/125 micron multimode fiber or 9/125
micron single-mode fiber.
INDUSTRY CANADA - CLASS A
This digital apparatus does not exceed the Class A limits for radio noise
emissions from digital apparatus as set out in the interference-causing
equipment standard entitled “Digital Apparatus,” ICES-003 of the Departmentof
Communications.
Cet appareil numérique respecte les limites de bruits radioélectriques applicables
aux appareils numériques de Classe A prescrites dans la norme sur le matériel

POWER CORD SAFETY
Please read the following safety information carefully before installing
the switch:
WARNING: Installation and removal of the unit must be carried out by qualified
personnel only.
 The unit must be connected to an earthed (grounded) outlet to comply with
international safety standards.
 Do not connect the unit to an A.C. outlet (power supply) without an earth
(ground) connection.
 The appliance coupler (the connector to the unit and not the wall plug) must
have a configuration for mating with an EN 60320/IEC 320 appliance inlet.
 The socket outlet must be near to the unit and easily accessible. You can
only remove power from the unit by disconnecting the power cord from the
outlet.
 This unit operates under SELV (Safety Extra Low Voltage) conditions
according to IEC 60950. The conditions
are only maintained if the
equipment to which it is connected also operates under SELV conditions.
France and Peru only
This unit cannot be powered from IT† supplies. If your supplies are of IT
type, this unit must be powered by 230 V (2P+T) via an isolation transformer
ratio
1:1, with the secondary connection point labelled Neutral, connected directly to
earth (ground).
