business services, both today and in the future. Each switch provides as many as 24
10/100-Mbps ports for desktop, wireless access point, printer, and IP phone connectivity,
as well as available 10/100/1000BASE-T Gigabit Ethernet and SFP optical connectivity
options. All switches in the Cisco Catalyst Express 520 Series also feature head-of-line
blocking prevention to help ensure that a heavily congested port will not affect performance
on other ports on the switch. Ultimately, you can more effectively manage and prioritize
your high-bandwidth traffic to keep employees productive and continually connected to
business applications.
PoE: Cisco Catalyst Express 520 Series Switches are available with as many as 24 PoE

ports, allowing you to power network attached devices such as IP phones, wireless access
points, video cameras, and other devices directly over the Ethernet connection, without an
external power supply, simplifying deployment and eliminating the need and cost of
installing separate power supplies for connected endpoints.
QoS: Cisco Catalyst Express 520 Series Switches feature QoS intelligence to prioritize
●
networking traffic such as voice, video, and data to help ensure consistent network
performance and to support delay-sensitive data such as real-time voice. The switches also
allow you to optimize QoS prioritization by using Cisco Smartports technology in Cisco
Configuration Assistant.
Simplified deployment and centralized management: You can easily deploy and
●
centrally manage Cisco Catalyst Express 520 Series Switches with Cisco Configuration
Assistant. This intuitive GUI-based application dynamically configures all products that are
part of the Cisco Smart Business Communications System, allowing you to quickly deploy
and centrally manage your entire office network. After the network is deployed, Cisco
Configuration Assistant can generate status reports, synchronize passwords, and upgrade
software across all of your Cisco network devices, reducing the time your staff must devote
to network deployment and configuration and allowing them to focus on your business
priorities. Cisco Configuration Assistant is available for download free of charge at

Robust security: Cisco Catalyst Express 520 Series Switches provide several layers of
●
security to protect your business. The switches provide embedded encryption capabilities to
help ensure that all management traffic to and from the device is protected with Secure
Sockets Layer (SSL) encryption. The Cisco Catalyst 520 Series also provides built-in
support for advanced security services. It includes IEEE 802.1x port security which helps
ensure that only authorized users and applications can access your wired and wireless LAN
and Cisco Network Admission Control (NAC) services, which verify that all devices entering
your network meet baseline security requirements. In addition, you can configure network
security options with the Cisco Configuration Assistant deployment interface, which allows
you to choose from three preset levels of security using a simple security slider control.
Simple monitoring and troubleshooting: Cisco Configuration Assistant makes
●
troubleshooting easy with Cisco Troubleshooting Advisor, which identifies cabling
problems, common configuration errors, and other potential problems in your network and
recommends corrective action. Graphical trend charts and an alert LED help you identify
problems before they cause network outages.
Easy integration with the Cisco Smart Business Communications System: The Cisco
●
Catalyst Express 520 Series was designed to integrate a complete system of advanced
voice, data, video, and wireless networking products designed specifically for SMBs. You
