		Power rating: 120 V (0.070 KVA), 240 V (0.071 KVA).
DC-Power Requirements
Input voltage		18 to 36 VDC or 36 to 72 VDC.
Power consumption with a		Total: 164 BTUs per hour (maximum).
single DC-power-supply		Maximum: 48 W (18 VDC input, maximum fan speed, all ports linked).
module installed
		Typical: 38 W (48 VDC, SFP modules installed, 12 ports linked).
		Minimum: 22 W (48 VDC, no SFP modules installed).
Power consumption with 2		Total: 245 BTUs per hour (maximum).
DC-power-supply modules		Maximum: 72 W, 18 VDC input (maximum fan speed, all ports linked).
installed
		Typical: 48 W (48 VDC, SFP modules installed, 12 ports linked).
