Technical Specifications

This appendix provides the technical specification for the Cisco IE 2000 switches.

Operating Temperature Specifications

Table A-1lists the operating temperatures for the Cisco IE 2000 switches in three different environments.

Table A-1	Operating Temperature for the Cisco IE 2000 Switches
	Industrial Automation and
	Hazardous Locations	Substation	Traffic Signal
Enclosure	Sealed enclosures	Vented enclosures	Fan or blower-equipped
types	For example: NEMA4, NEMA4X,	For example: NEMA1, IP20, and	enclosures
	NEMA12, NEMA13, IP54, and	IP21.	For example: NEMA TS-2.
	IP66.		Note The minimum airflow is
			150 lfm1.
Operating	–40 to 140°F (–40 to 60°C)	–40 to 158°F (–40 to 70°C)	–29 to 167°F (–34 to 75°C)
temperature2

1.lfm = linear feet per minute.

2.Operating temperature ranges provided are based on the stated NEMA standards. The switch is test verified for operation to -40°F/40°C. There is no safety coverage outside of these parameters.

Note The safety certifications apply only to ambient temperatures under 140°F (60°C). However, the Cisco IE 2000 switch can function in the substation and traffic signal installations under the environmental conditions shown in Table A-1.
