Intelligent Power over Ethernet (PoE) Management

The Cisco Catalyst 3750-E PoE models support Cisco IP phones and Cisco Aironet WLAN access points, as well as any IEEE 802.3af-compliant end device. The Cisco Catalyst 3750-E-48PD can support 48 simultaneous full-powered PoE ports at 15.4W with the 1150W power supply.

Cisco Discovery Protocol version 2 (CDPv2) allows the Cisco Catalyst 3750-E Series Switch to negotiate a more granular power setting when connecting to a Cisco powered device such as IP phones or access points than what is provided by IEEE classification.

Per Port power consumption command allows customers to specify maximum power setting on an individual port.

Per Port PoE Power Sensing measures actual power being drawn, enabling more intelligent control of powered devices.

The PoE MIB provides proactive visibility into power usage and allows customers to set different power level thresholds

Power Connectors

Customers can provide power to a switch by using either the internal power supply or the Cisco RPS 2300. The connectors are located at the back of the switch.

Internal power supply connector: The internal power supply is an auto-ranging unit. The internal power supply supports input voltages between 100 and 240VAC. Use the supplied AC power cord to connect the AC power connector to an AC power outlet.

Cisco RPS connector: The connector offers connection for an optional Cisco RPS 2300 that uses AC input and supplies DC output to the switch.

Only the Cisco RPS 2300 (model PWR2300-AC-RPS-N1=) should be attached to the redundant-power-supply receptacle.
