Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY Specification Guide

 lists the specifications for the 6000 W AC-input power supply.

AC-input type

2 AC-inputs per power supply. High-line input with 
power factor correction (PFC) included.

Power factor correction is a standard feature on 
all Catalyst 6500 series AC-input power 
supplies. PFC reduces the reactive component 
in the source AC current allowing higher power 
factors (typically 99 percent or better) and 
lower harmonic current components.

AC-input voltage

100 to 120 VAC, single-phase (low line)

200 to 240 VAC, single-phase (high line)

AC-input current

16 A each input 

kVA rating

7.5 kVA

AC-input frequency

50/60 Hz (nominal) (±3% for full range)

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:

2900 W maximum with the following source AC 
arrangements:

INPUT 1 and INPUT 2 both connected to 
110 VAC

INPUT 1 connected to 220 VAC; INPUT 2 
not connected

INPUT 1 not connected; INPUT 2 connected 
to 220 VAC

INPUT 1 connected to 220 VAC; INPUT 2 
connected to 110 VAC

INPUT 1 connected to 110 VAC; INPUT 2 
connected to 220 VAC

6000 W maximum

1

 with the following source AC 

arrangements:

INPUT 1 and INPUT 2 both connected to 
220 VAC

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 
110 VAC.
