Cisco Systems 520 manual Catalyst Express Switch Network Example

Chapter 1 Introduction

Overview

•Switches C and D: Use the Catalyst Express 520-24TT-K9 or the Catalyst Express 520G-24TC-K9 model to provide high-speed (up to 100 Mb/s and 1000 Mb/s, respectively) connections to network users.

You can also use the Catalyst Express 520-24LC-K9 or the Catalyst Express 520-24PC-K9 model to connect Cisco prestandard and IEEE 802.3af-compliant powered devices, such as IP phones and access points, to your network. PoE connections from these switches can provide both network access and power for up to 4 or up to 24 PoE devices, respectively.

If the switch detects that there is no power on the circuit, the PoE ports provide up to 15.4 W of power to attached PoE devices. You can place PoE devices where power outlets are not available or are not convenient and thus avoid cabling costs.

You can manage the network onsite or remotely through the Cisco Configuration Assistant network management application. Through Cisco Configuration Assistant, you can also optimize the switches. For example, you can configure VLANs that give priority to voice traffic over regular data traffic from the desktop devices attached to the IP phones. Other VLANs can provide different types of network users—wired employees, wireless (or mobile) employees, and wired and wireless company visitors—with different access levels to the company network.
