Appendix A Power Supply Specifications
8700 W AC-Input Power Supply
Note
Because 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.

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.
Note
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
(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)
