CHAPTER 1
Introduction
Read this chapter to familiarize yourself with the features, benefits, and 
capabilities of the Catalyst Express 500 switches.
Note This chapter and the rest of this guide focus on the concepts and tasks that are 
available from the switch hardware and the device manager GUI that is embedded 
in the switch software.
Enhanced Catalyst Express 500 features and procedures are only available from 
the Cisco Network Assistant network management application. This application

                        Chapter 1      Introduction Overview   Overview The Catalyst Express switches (Table 1-1) provide networking for businesses  with up to 250 employees. These switches provide network services to support  data, voice, and mobile network demands. The services ensure transmission  quality and reliability for data and voice traffic. They also provide security to  protect against network attacks. You can simply install the switch and allow it to operate without any further  management intervention. Yo

Devices  outside the dotted line are network users and network resources, such as servers  and printers. Devices within the dotted line are switches, routers, and access  points that enable communication between network users and provide access to  network resources.

                        Chapter 1      Introduction Features and Benefits   PoE connections from the switch provide both power and network access to  PoE-capable devices, such as IP phones and access points. PoE devices can  receive up to 15.4 W of power from their connections to the switch. PoE also helps  reduce cabling costs. You can place PoE devices where power outlets are not  available or are not convenient. Multiple connections between the switches ensure that users maintain network  access if any of the switch
