Appendix A Power Supply Specifications
8700 W AC-Input Power Supply
Power supply output
capacity
The power supply output capacity is dependent on the number of AC
power cords (1, 2, or 3) attached and the source AC voltage (110 VAC
[low-line] or 220 VAC [high-line]) applied to the power supply inputs.
The 8700 W AC-input power supply is limited to reduced wattage
ratings when it is installed in the following Catalyst 6500 series chassis:
• 4000 W maximum output when it is installed in a Catalyst 6506,
Catalyst 6509, or Catalyst 6509-NEB switch chassis.
• 4500 W maximum output when it is installed in the
Catalyst 6509-NEB-A switch chassis.
• 6000 W maximum output when it is installed in the Catalyst 6513
switch chassis.
Note The power supply will not power up if you attach only one power
cord and the power cord is connected to low-line (110 VAC
nominal) source AC.
2800 W operation 2800 W maximum with the following combinations of power cords and
source AC voltage applied to the power supply inputs:
• Two AC inputs are connected to low-line (110 VAC nominal); the
third AC input is not connected.
• One AC input is connected to low-line (110 VAC nominal); one AC
input is connected to high-line (220 VAC nominal); the third AC
input is not connected.
• One AC input is connected to high-line (220 VAC nominal); two AC
inputs are not connected.
4200 W operation 4200 W maximum with the following combinations of power cords and
source AC voltage applied to the power supply inputs:
• All three AC inputs are connected to low-line (110 VAC nominal).
• Two AC inputs are connected to low-line (110 VAC nominal); one
AC input is connected to high-line (220 VAC nominal).
5800 W operation 5800 W maximum with the following combinations of power cords and
source AC voltage applied to the power supply inputs:
• Two AC inputs are connected to high-line (220 VAC nominal); the
third AC input is connected to low-line (110 VAC nominal).
• Two AC inputs are connected to high-line (220 VAC nominal); the
third AC input is not connected.
8700 W operation 8700 W maximum with the following combinations of power cords and
source AC voltage applied to the power supply inputs:
• All three AC inputs are connected to high-line (220 VAC nominal).
