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.

Cisco Configuration Assistant

Compared to the switch device manager, the Cisco Configuration Assistant offers an enhanced set of features for configuring, monitoring, and troubleshooting the devices in your network.

The Cisco Configuration Assistant discovers all devices in the network and can configure all supported routers, switches, and wireless access points and controllers as well as Cisco Unified Communications call-routing and voice-mail systems. After the network is deployed, you also can use Cisco Configuration Assistant to generate status reports, to synchronize passwords, and to upgrade software across all of your Cisco network devices.

Some general Cisco Configuration Assistant features include:

• Centralized, common services—such as software upgrades, configuration

management, inventory reports, network events, alerts, and password and configuration synchronization—for Cisco switches, routers, access points, and voice appliances in the network

• Centralized network monitoring using two views of all connected devices in

the network: a physical view (Front Panel image) and a logical view (network Topology image) of different network devices

• Drag-and-drop software upgrade for multiple devices, including backup and

restoration of device configuration files

• Security configuration for all the Cisco access points in the network

• Authenticated and encrypted communications between the Cisco

Configuration Assistant client and each connected network device

• Simplified troubleshooting through an Events Notification Advisor (which

identifies problems and suggests resolutions related to misconfiguration such as Smartports or duplex-mode mismatch) and through a Link Diagnostic Report (which identifies problems and suggests resolutions related to connectivity such as port-speed mismatch and faulty cabling)

The Cisco Configuration Assistant is available in a number of languages.

CHAPTER

Setting Up the Switch

The switch can operate without an IP address assigned to it. However, we recommend setting up the switch with an IP address so that you can manage it through the device manager and the Cisco Configuration Assistant. Otherwise, your switch management is limited to using only the LEDs on the switch front panel.

For best results in setting up the switch, first follow the procedures in the getting started guide that ships with the Cisco Unified Communications 500 Series. This document is also available on the CD-ROM that ships with the switch.

If you do not have a Cisco Unified Communications 500 Series, follow the guidelines and procedures in this chapter.

Before You Begin

Before you set up the switch, review the information in the Release Notes for the Catalyst Express 520 Switches on Cisco.com.

Before you power or install the switch, review the safety information the

“Warnings” section on page 2-2.

Warning

To prevent the switch from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 113°F (45°C). To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings.

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.
