Technical Specifications
Table A-1 lists the operating temperatures for the Cisco IE 3000 switches, modules, and power
convertor. Table A-2 lists the technical specifications for the switches and modules. Table A-3 lists the
technical specifications for the Cisco IE 3000 switch power converter.
The operating temperature for the Cisco IE 3000 switches, modules, and the power convertor varies
among environments, based on factors such as the system configuration and enclosure types.
Table A-1
describes three different environments and the operating temperature for each of the environments.
Note The safety certifications apply only to ambient temperatures under 140°F (60°C). However, the
Cisco IE 3000 switch can function in the substation and traffic signal installations under the
environmental conditions shown in Table A-1.
