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 or 220 VAC) applied to
the power supply inputs.
Note The 8700 W AC-input power supply is limited
to 4000 W maximum output when it is installed
in a Catalyst 6506, Catalyst 6509, or Catalyst
6509-NEB switch chassis. The power supply is
limited to 4500 W maximum output when it is
installed in the Catalyst 6509-NEB-A switch
chassis and 6000 W when it is installed in a
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).
