Specifications

			Dimensions
			The switch may be configured for either rack mount or tabletop use.
			Rack Mount Dimensions
			2U, 19-in. rack mount (EIA compliant)
			H: mm (1.71 in.), W: 428.6 mm (16.88 in.), D: 450.0 mm (17.72 in.)
			Table Top Dimensions
			H: mm (1.86 in.), W: 428.6 mm (16.88 in.), D: 450.0 mm (17.72 in.)
			Weight

Power Supply			The switch has a universal power supply capable of functioning
			worldwide without voltage jumpers or switches. The supply is
			autoranging in terms of accommodating input voltages and line
			frequencies. A semi-custom switching power supply, repackaged for
			the requirements of the switch enclosure architecture, is used.
			The power supply meets the requirements shown in Table A-5.
	Table A-5Power Supply Requirements
		Specification		Value
		Total power		155 watts
		Input voltage		85 to 265 VAC
		Input line frequency		47 to 63 Hz
		Inrush Current		10 Amps Peak, > 300 usec - hot/cold start
		Harmonic Distortion		Active power factor correction per IEC1000-3-2
		Input Line Protection		Fused in both hot & neutral lines
		Maximum Dimensions		3.5”W X 1.5”H X 11”L
