Catalyst 6503 Switch

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.
