COMPLIANCES AND SAFETY
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.
