can quickly deploy and configure all components in the Cisco Smart Business 

Communications System, including the Cisco Catalyst Express 520 Series using Cisco 

Configuration Assistant.  

 

Ease of use: The Cisco Catalyst Express 520 Series was designed for ease of use by 

SMBs without dedicated networking resources. You can deploy the switches in minutes 

using Cisco Configuration Assistant’s intuitive GUI without ever having to learn command-

line interfaces or complex administrative terminals. Cisco Configuration Assistant can 

dynamically configure your switches or suggest recommended settings for all ports and let 

you choose from preset options with Cisco Smartports Advisor. In addition, all ports support 

autonegotiation of port speed, data rate, and duplex mode. The Cisco Catalyst Express 520 

Series includes automatic medium-dependent interface crossover (Auto-MDIX) detection 

support, which determines the wire pair to use for transmitting and receiving data and 

avoids the use of incorrect cable types.  

 

Limited Lifetime Warranty: All Cisco Catalyst switches are protected for the life of the 

product by the Cisco Limited Lifetime Hardware Warranty and include free Cisco IOS 

Software updates. For more information about the Cisco Limited Lifetime Warranty, visit
