Description
Chassis
Three horizontal slots. Slots are numbered from 1 (top) to 3 (bottom).
Power supplies
•
Supports one or two power supplies. The following power supplies are
supported:
–
950 W AC-input power supply (PWR-950-AC)
–
950 W DC-input power supply (PWR-950-DC)
–
1400 W AC-input power supply (PWR-1400-AC)
Note
For information and specifications for each of the supported power
supplies, refer to Appendix A, “Power Supply Specifications,” in the
Catalyst 6500 Series Switches Installation Guide
.
•
Installed power supplies can be of different wattage ratings. Installed
power supplies can be both AC-input, both DC-input, or one AC-input
and one DC-input. Power supplies can be configured in either redundant
or nonredundant mode.
Note
For Catalyst 6503 and Catalyst 6503-E chassis that are equipped
with DC-input power supplies, the system (NEBS) ground serves as
the primary safety ground and must be installed. The DC-input
power supplies for these chassis do not have a separate ground.
•
All Catalyst 6500 series AC-input power supplies require single-phase
source AC. Source AC can be out of phase between multiple power
supplies or multiple AC-power plugs on the same power supply because
all AC power supply inputs are isolated.
•
Single power supplies are installed in the lower power supply bay. The
second power supply is installed in the upper power supply bay.
