Power enters the switch through the power supplies. Several types of power supplies are available, depending on the power needs for your system and the power type available on your site. All power supplies provide a 3.3 V circuit (shown as a dash-dot line) to the components on the backplane and a 12 V circuit (shown as a solid line) that is carried over the backplane to the fans, supervisor engine, and switching modules. Power supplies that support PoE (1300 W AC, 2800 W AC, 4200 W AC or 1400 W DC) also provide a –48 V circuit (shown as a dashed line) to PoE-enabled switching modules, which is then available to the powered device connected to the switching module.

Note The Supervisor Engine II-Plus TS has internal DC-to-DC converters that use the 12 V circuit to provide PoE to powered devices connected to the Supervisor engine only. If your system has a Supervisor Engine II-Plus TS in slot 1, you still need a PoE-enabled power supply to provide PoE to the other slots.

All Catalyst 4500 E-series switches support dual power supplies, configurable for combined mode or redundant mode. In combined mode, the switch has available the combined rated wattage of both power supplies, less some expected efficiency loss. In redundant mode, one power supply provides power to the system and the other supply is on standby should there be a failure in either the power supply or the input voltage source it is connected to.

Power over Ethernet

The Cisco Catalyst 4500 E-series switches support the 802.3af standard for PoE on 10/100 or 10/100/1000 ports, enabling customers to support telephones, wireless base stations, video cameras, and other appliances. PoE makes it possible to place devices in unique locations without having to provide
