Catalyst 4500 Series Power Supplies

Table A-14shows the wattage output possible with the 4200W power supply in redundant mode. In redundant mode, both power supplies must have identical inputs and all inputs must be at the same voltage. If the input voltages are mismatched, choose the value matching the weaker of the two power supplies.

Table A-14	Redundant Mode Output
		12V	3.3V	-50V	Total
110		660	40	700	1050
110+110 or 220		1360	40	1850	2100
220+220		1360	40	3700	4200

Table A-15shows the wattage output possible with the 4200W power supply in conbined mode.
