Chapter 1 Introduction

Hardware Features

The PoE ports provide up to 15.4 W of power to connected Cisco prestandard and IEEE 802.3af-compliant powered devices if the switch detects that there is no power on the circuit. On a per-port basis, through the Cisco Configuration Assistant, you can control whether the PoE port automatically provides power when a powered device is connected. By default, the setting is Auto.

Note On the Catalyst Express 520-24LC-K9 switch, ports 1 to 4 are PoE ports.

Use the Cisco Configuration Assistant to change the port settings.

12Port LEDs The port LEDs show port status, port duplex mode, port speed, and PoE status. By default, the port LEDs show port status.

 

Use the Cisco Configuration Assistant to change and to monitor the port settings.

 

Note To display the port duplex mode, the port speed, and the PoE status from

 

the port LEDs, you must use the View list from the device manager. See

 

Table 6-2and the device manager online help for information about the

 

View list.
