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.
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.
