6000 W AC-Input Power Supply
Power supply output capacity The 6000 W power supply can operate at either
2900 W or 6000 W depending on the number of AC
power cords attached and the source AC voltage.
Note The 6000 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.
• 2900 W maximum with the following source AC
arrangements:
– INPUT 1 and INPUT 2 both connected to
low-line (120 VAC nominal)
– INPUT 1 connected to high-line (230 VAC
nominal); INPUT 2 not connected
– INPUT 1 not connected; INPUT 2 connected
to high-line (230 VAC nominal)
– INPUT 1 connected to high-line (230 VAC
nominal); INPUT 2 connected to low-line
(120 VAC nominal)
– INPUT 1 connected to low-line (120 VAC
nominal); INPUT 2 connected to high-line
(230 VAC nominal)
• 6000 W maximum with the following source AC
arrangements:
– INPUT 1 and INPUT 2 both connected to
high-line (230 VAC nominal)
Note The 6000 W power supply will not power up if
you have only one power cord plugged into
either INPUT 1 or INPUT 2 and source AC is
low-line (120 VAC nominal).
