It has 8 10/100 PoE ports for desktop, printer, IP phone, server, and wireless access-point connectivity •...
Page 16 Introduction Overview Cisco Smart Business Communications System Network Example The Catalyst Express 520 switches are the recommended companion switches to the Cisco Unified Communications 500 Series. These devices are part of the Cisco Smart Business Communications System solution (Figure 1-1).
Page 17 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.

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.
Page 19 Chapter 1 Introduction Hardware Features SYSTEM LED The SYSTEM LED shows the status of the switch (system). Solid green Switch is healthy. Blinking green Switch is running power-on self-test (POST). POST is a series of tests that runs automatically to ensure that the switch functions properly.
Page 20 Chapter 1 Introduction Hardware Features ADMIN LED The ADMIN LED shows the management mode in which the switch is operating. Off (dark) Switch is configured with an IP address. Blinking green Switch is in the initial setup mode, or the switch is in direct managed mode.
Page 21 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.
