This section contains warning information for AC powered systems.
Servicing Service of this unit is to be performed by qualified service personnel only.
Service of certain components and subassemblies in this equipment is
accomplished by the replacement of Field Replaceable Units (FRUs). However,
safety agency approval requires that the servicing of other subassemblies within
this product be referred to 3Com’s service personnel.
The trim enclosure and other mechanically secured plates serve as protection
barriers from potential hazardous internal areas. No attempt should be made to
troubleshoot internal components with these protective barriers removed
without first disconnecting the equipment from main power.
Rack Mounting This equipment is for use only in complete equipment where the acceptability of
the combination is determined by the applicable safety agency in the country in
which it is installed. This includes UL in the U.S.A., CSA in Canada, and TUV in
Europe.
Conditions of Acceptability: When installed in the end-use equipment, the
following are among the considerations to be made.
1 The units shall be installed in compliance with enclosure, mounting, spacing,
casualty, and segregation requirements of the ultimate application.
2 These units have been judged on the basis of the required spacings of UL 1950
D3 deviations edition, CSA 22.2 No. 950-M89, and EN 60950 1988 through
TUV Rheinland, which would cover these components if submitted for
unrestricted listing or certification.
3 Complete testing should be performed in the end-use product.
4 Rack configurations with certain combinations of 3Com equipment installed in
racks with a height greater than 50” (127 cm) may require a counter-balance
weight, a stabilizer bar, or anti-tip legs to ensure rack stability in accordance
with safety agency regulations. See specific rack installation guidelines for 3Com
recommendations.
Power and Power
Cords
This equipment is not intended for use with IT power distribution systems
whose line to line voltage exceeds 250 VAC RMS defined by EN 60950 as
having no direct connection to earth. The PathBuilder S600 WAN Access Switch
will autoconfigure for 115 VAC or 220-240 VAC.

NFORMATION
NORTH AMERICAN APPLICATIONS: Use a UL Listed and CSA Certified Cord Set
rated 6 amps, consisting of a minimum 18 AWG, Type SVT or SJT three
conductor cord maximum of 15 feet in length, with a NEMA 5-15P plug.
INTERNATIONAL APPLICATIONS: The power supply cords used with this
equipment should be harmonized with all local standards applicable in the
country in which it is installed.
Safety agency compliance requires this unit to be connected to branch circuits
with overcurrent protection
£ 20A for North American applications and £ 10A
for international applications.
The power supply cord must be disconnected when servicing all components or
subsystems.
EMI FCC - This equipment generates, uses, and can radiate radio frequency energy,
and if not installed and used in accordance with the instruction manual, may
cause interference to radio communications. It has been tested and found to
comply with the limits for a Class A computing device pursuant with Part 15 of
the FCC Rules, which are designed to provide reasonable protection against
such interference when 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
required to correct the interference. These tests were conducted with shielded
communications cables with metal connector hoods; the use of unshielded
cables may void this compliance.
Canada - This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus set out in the Radio Interference
Regulations of the Canadian Department of Communications.
Europe - This is a Class A product. In a domestic environment this product may
cause radio interference, in which case, the user may be required to take
adequate measures.
Safety Classification
of Ports for
Connection to
Telecommunications
Networks
The following port types in the product range are classified according to the
Harmonized Europeans Standard EN41003, subclause 4.1.3, as follows:
E1/E3 - TNV normally operating within SELV limits (TNV-1)
1
Telecommunications Network Voltage (EN60950, subclause 1.2.8.8)
2
Safety Extra-Low Voltage (EN60950, subclause 1.2.8.5)
