1		AC power	The internal power supply is an autoranging unit that supports input voltages
		connector	between 100 and 240 VAC. Use the supplied AC power cord to connect the AC
			power connector to an AC power outlet.
2		RPS	Depending on the Catalyst Express 520 model, a Cisco RPS 675 can be
		connector	connected to the switch. The RPS is a redundant power system that automatically
			senses when the internal power supply of a connected device fails and provides
			power to prevent the loss of network traffic. For complete information about the
			RPS, see the Cisco RPS 675 Redundant Power System Hardware Installation
			Guide on Cisco.com.
			Warning Attach only the Cisco RPS (model PWR675-AC-RPS-N1=) to the RPS
				receptacle. Statement 100C
3		Security slot	The security slots are on the left and right side panels. You can install an optional
			cable lock, such as the type that is used to secure a laptop computer, to secure
			either or both sides of the switch.
