High reliability: Cisco ESW 500 Series Switches have been developed and rigorously

tested to provide reliable connectivity and performance, especially when supporting

advanced voice, video, and wireless services. They also support an optional redundant

power supply that provides uninterrupted failover to help ensure continuous operation,

without the need to reboot, even if the primary power supply fails. These features help you

keep your network available, prevent costly downtime, and keep your employees and

customers connected to the applications they need.

●

Power over Ethernet: Cisco ESW 500 Series Switches are available with up to 48 PoE

ports of Fast Ethernet and 24 PoE ports of Gigabit Ethernet connectivity. PoE allows you to

power network-attached devices such as IP phones, video cameras, and wireless access

points directly over the Ethernet connection, without an external power supply. The result is

a simpler and less expensive deployment, without the need to install a separate power

supply for each connected endpoint.

●

Quality of service: Cisco ESW 500 Series Switches feature QoS intelligence to prioritize

delay-sensitive and high-bandwidth network traffic, enhancing network performance and

allowing businesses to support demanding services such as real-time voice and video.

●

Simple configuration and management: Cisco ESW 500 Series Switches are designed

to be configured and managed by small businesses or the Cisco partners that serve them.

Whether you are installing a single switch or an advanced voice and video communications

system, simple graphical user interfaces (GUIs) help your staff easily configure, manage,

and troubleshoot your network. The Cisco ESW 500 Series includes an embedded web-

based Configuration Utility Device Manager designed specifically for setting up the ESW

500 switch (Figure 3).

For system wide deployments, you can use the Cisco Configuration Assistant, a GUI-based

application that configures all of the devices that are part of Small Business Pro Series as well as

the Cisco Smart Business Communications System. Both the device manager and Cisco

Configuration Assistant feature Cisco Discovery Protocol to automatically discover all Cisco

devices and allow them to share information about one another. They also employ Cisco

Smartports technology, which provides preset options for quickly configuring all ports on a Cisco

ESW 500 Series Switch, including QoS, and security features (Figure 4). Once the network is
