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...
100 and 240 VAC. Use the supplied AC power cord to connect the AC power connector to an AC power outlet. Depending on the Catalyst Express 520 model, a Cisco RPS 675 can be connector connected to the switch. The RPS is a redundant power system that automatically senses when the internal power supply of a connected device fails and provides power to prevent the loss of network traffic.

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.
