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
