Overview
Overview
The Catalyst Express 520 switches provide network services that can support the
data, voice, and mobile network demands of small and medium-sized businesses.
The services ensure transmission quality and reliability for data and voice traffic.
They also provide security to protect against network attacks.
The Catalyst Express 520 switches are designed to be
•Smart—Each switch port is applied with a specific Cisco-recommended
configuration (referred to as a Smartports port role) to optimize the switch
connections and to ensure security, transmission quality, and reliability for
traffic from the switch ports.
•Simple—Setup of the switch can be through a connection to an existing
network with a Dynamic Host Configuration Protocol (DHCP) server, such
as a Cisco Unified Communications 500 Series, or through the Express Setup
feature of the switch device manager GUI.
•Secure—The switch supports three levels of business-optimized network
security. Traffic between the switch and the network management
applications is also encrypted through the Secure Sockets Layer (SSL)
protocol.
You can simply install the switch and allow it to operate without any further
management intervention. Use device and network management tools to take
advantage of the software features and to optimize your use of the switch. With
these tools, you can quickly and easily set up, customize, monitor, and
troubleshoot the switch.
