Figure 1-3 Hardware Features
1AC power
connector
The internal power supply is an autoranging unit that supports input voltages
between 100 and 240 VAC. Use the supplied AC power cord to connect the AC
power connector to an AC power outlet.
2 RPS
connector
Depending on the Catalyst Express 520 model, a Cisco RPS 675 can be
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.
