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.

Indicators

• Per-port status LEDs: link integrity, disabled, activity, speed, and full-duplex indications
• System-status LEDs: system, RPS, and bandwidth-utilization indications
