1400 W Power Supply AC Power Cords
Ta b l e A - 1 6 lists the specifications for the AC power cords that are available for the 1400 W AC-input 
power supply. These power cords plug into the 1400 W PEM (PEM-20A-AC+); not directly into the 
power supply. The table includes references to power cord illustrations.
NoteAll 1400 W power supply power cords are 14 feet (4.3 meters) in length.
NoteAll 1400 W power supply power cords have an IEC60320/C19 appliance plug at one end.
Table A-15 1400 W AC-Input Power Supply LEDs
LED Meaning
INPUT OK
Green—Source AC voltage is OK. (Input voltage is 85 VAC or 
greater.)
Off—Source AC voltage falls below 70 VAC, is not present, or the 
power supply is turned off.
FAN OK
Green—Power supply fan is operating properly. 
Off—Power supply fan failure is detected.
OUTPUT FAIL
Red—Problem with one or more of the DC-output voltages of the 
power supply is detected.
DC-output voltages within acceptable margins.
NoteFor proper operation of the OUTPUT FAIL LED, systems with 
single power supplies must be configured with a minimum of 
one fan tray and one supervisor engine. Systems with dual power 
supplies must have a minimum configuration of one fan tray, one 
supervisor engine, and one additional module. Failure to meet 
these minimum configuration requirements can cause a false 
power supply output fail signal.

  2500 W AC-Input and DC-Input Power Supplies
2500 W AC-Input and DC-Input Power Supplies 
The 2500 W AC-input power supply (WS-CAC-2500W) and 2500 W DC-input power supply 
(WS-CDC-2500W) are supported in the following Catalyst 6500 series switches:
Catalyst 6506
Catalyst 6506-E
Catalyst 6509
Catalyst 6509-E
Catalyst 6509-NEB
Catalyst 6509-NEB-A
Catalyst 6509-V-E
Catalyst 6513
Catalyst 6513-E (DC-input power supply only)
The 2500 W power supplies, shown in Figure A-9 and Figure A-10, share the same form factor as the 
1000 W, 1300 W, 3000 W, 4000 W, and 6000 W AC-input power supplies.
NoteWith a fully populated Catalyst 6513 switch, two 2500 W power supplies are not fully redundant. If you 
operate the 2500 W power supply at the low range input (100 to 120 VAC), it is not redundant in a fully 
populated Catalyst 6509, Catalyst 6509-E, Catalyst 6509-NEB, Catalyst 6509-NEB-A, or 
Catalyst 6509-V-E switch.
NoteThe 2500 W AC-input power supply needs 220 VAC to deliver 2500 W of power. When powered with 
110 VAC, it delivers only 1300 W. In addition, the power supply needs 16 A, regardless of whether it is 
plugged into 110 VAC or 220 VAC.

Table A-17 2500 W AC-Input Power Supply Specifications
Specification Description
AC-input type Autoranging input with power factor correction (PFC).
NotePower 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
Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)
High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)
AC-input current 16 A maximum at 230 VAC at 2500 W output
16 A maximum at 120 VAC at 1300 W output
AC-input frequency 50/60 Hz (nominal) (±3% for full range)

  2500 W AC-Input and DC-Input Power Supplies
Ta b l e A - 1 8 lists the specifications for the 2500 W DC-input power supply. Branch circuit requirement Each chassis power supply should have its own dedicated, fused-branch 
circuit:
For North America—20 A
For International—Circuits sized to local and national codes
All AC power supply inputs are fully isolated.
–Source AC can be out of phase between multiple power supplies 
in the same chassis, which means that PS1 can be operating 
from phase A and PS2 can be operating from phase B.
–For high-line operation, the power supply operates with the hot 
conductor wired to a source AC phase and the neutral conductor 
wired either to ground or to another source AC phase as long as 
the net input voltage is in the range of 170 to 264 VAC.
–Source AC can be out of phase between AC inputs on power 
supplies that are equipped with multiple AC inputs, which 
means that power cord 1 can be plugged into phase A and 
power cord 2 can be plugged into phase B.
