A Simple, Powerful Platform
Designed specifically for SMBs, the Cisco Catalyst Express 520 Series can be deployed quickly and managed
centrally using the Cisco Configuration Assistant. This easy-to-use tool provides straightforward graphical
interfaces to simplify the management, troubleshooting, and ongoing optimization of the Cisco Catalyst Express
520 Series as well as all the devices in the Cisco Smart Business Communication System.
centrally using the Cisco Configuration Assistant. This easy-to-use tool provides straightforward graphical

520 Series as well as all the devices in the Cisco Smart Business Communication System.
After the network is deployed, Cisco Configuration Assistant can generate status reports, synchronize pass-
words, 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 makes
troubleshooting easy with the Cisco Troubleshooting Advisor,
which identifies cabling problems, common configuration errors,
and other potential problems in your network before they cause
network outages.

Strong, Integrated Security
The Cisco Catalyst Express 520 Series provides 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, including 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 easily configure network security options with the Cisco
Configuration Assistant, which allows you to choose from three
preset levels of security using a simple “security slider.”

An Adaptable Network Foundation
The Cisco Catalyst Express 520 Series also prepares your
network for the future. The switches feature embedded QoS
intelligence to prioritize voice, video, and data networking traffic,
allowing you to help ensure consistent network performance
and to support delay-sensitive services such as real-time voice.
Cisco Catalyst Express 520 switches are also available with as
many as 24 PoE ports, allowing you to power IP phones, wireless
access points, or IP video cameras directly over the Ethernet
connection. In addition to making it easier to take advantage of
advanced voice, video, and wireless services, PoE simplifies
deployment by eliminating the need and cost to install separate
power supplies for each connected network endpoint.
