NFORMATION

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.

The units shall be installed in compliance with enclosure, mounting, spacing,

casualty, and segregation requirements of the ultimate application.

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.

Complete testing should be performed in the end-use product.

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 S700 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 12 amps, consisting of a minimum 10 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)

Telecommunications Network Voltage (EN60950, subclause 1.2.8.8)

Safety Extra-Low Voltage (EN60950, subclause 1.2.8.5)
