Chapter 1 Catalyst 6500 Series Switch Chassis Overview Catalyst 6503 Switch Table 1-1 Catalyst 6503 Switch Features Feature Chassis Power supplies Description Three horizontal slots. Slots are numbered from 1 (top) to 3 (bottom). • 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. OL-6265-03 Catalyst 6500 Series Ethernet Modules Installation Guide 1-3

Table 1-1
Catalyst 6503 Switch Features
Feature
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.
