power supply is turned off.
INPUT OK 1, INPUT OK 2, 
INPUT OK 3, and INPUT 
OK 4
(DC-input power supply 
only)
Green—Source DC voltage is greater than or equal to –40.5 VDC.

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

  8700 W AC-Input Power Supply
NoteBecause of the form-factor difference, when you install an 8700 W power supply in a Catalyst 6506, 
Catalyst 6509, or Catalyst 6509-NEB chassis you must relocate the system ground connection from the 
chassis ground pad connection to the two system ground studs located on the 8700 W power supply 
faceplate. Installing an 8700 W power supply in the other Catalyst 6500 series chassis does not require 
that you move the chassis system ground connection to the power supply.
The 8700 W power supply cannot be installed in the Catalyst 6503, Catalyst 6503-E, and 
Catalyst 6504-E switch chassis.

Table A-38 8700 W AC-Input Power Supply Specifications
Specification Description
AC-input type 3 AC-inputs per power supply. High-line input with power factor 
correction (PFC) included.
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
(One-phase)
Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)
High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)

  8700 W AC-Input Power Supply
AC-input current 16 A each input 
AC-input frequency 50/60 Hz (nominal) (±3% for full range)
Branch circuit requirement  Each power supply input should have its own dedicated, fused-branch 
circuit:
For North America—20 A
For International—Circuits should be sized according to local and 
national codes
All Catalyst 6500 series AC-input power supplies require 
single-phase source AC.
All AC power supply inputs are fully isolated. This means that 
source AC can be out of phase between multiple AC inputs on the 
same power supply or different AC power supplies that are installed 
in the same chassis. For the 8700 W power supply, this means that 
power cord 1 can be plugged into phases A-B, power cord 2 can be 
plugged into phases B-C, and power cord 3 can be plugged into 
phases C-A, A-B, or B-C.

Appendix A      Power Supply Specifications
  8700 W AC-Input Power Supply
Remote Power Cycling Feature
The 8700 W power supply is equipped with a remote power cycling feature that allows you to remotely 
turn on or turn off the power supply through an external relay controller box. Figure A-19 shows a 
typical remote power on/off setup. A three-position terminal block and a switch, located on the lower 
right quadrant of the power supply faceplate (see Figure A-18), provide the interface to the external relay 
controller box.
Figure A-19 Remote Power On/Off Feature Components
Terminal Block
The terminal block has three contacts labeled 1, 2, and 3. Two control wires from an external relay 
controller box attach to either positions 1 and 2 or positions 2 and 3. Positions 1 and 2 are used when the 
relay controller box contains a normally-open (NO) type of relay. Positions 2 and 3 are used when the 
relay controller box contains a normally-closed (NC) type of relay. 
Relay Controller Box Switch 
The relay controller box switch, located next to the terminal block, allows you to match the power supply 
power control signal’s active state with the type of relay contained in the external relay controller box 
(either a normally-open type of relay or a normally-closed type of relay). 
Ferrite Bead
A plastic bag containing one ferrite bead and two 4-inch plastic ties is included with the 8700 W power 
supply AC power cords. The ferrite bead is a passive device that limits high-frequency interference on 
interface and control cables, and is only required when you install the remote power-cycling feature that 
is supported by the 8700 Watt power supply. The ferrite bead is installed on the two control wires that 
come from the relay controller box to the terminal block on the 8700 W power supply. The ferrite bead 
should be installed as close as possible to the power supply terminal block for the bead to be effective. 
You do not need the ferrite bead for 8700 Watt power supply installations that do not include the remote 
power-cycling feature. If you need to install the ferrite bead, refer to “Installing the Ferrite Bead” 
procedure on page 1-100.
