Catalyst 4500 Power Supplies
Note The 4200 W AC power supply should not be used in mixed-voltage configurations. All the inputs in a
chassis must be at the same voltage (110 VAC or 220 VAC ) .
Table A-14 shows 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-15 shows the wattage output possible with the 4200 W power supply in combined mode.
Maximum KVA rating 5.25 KVA
