10/100/1000 PoE+ ports and their capabilities

The WS-C3750E-48PD-EF has 48 10/100/1000 PoE+ ports, which are ports that are capable of providing both data connectivity and power to devices connected to them. The PoE+ feature allows the switch to supply power to devices such as IP phones, wireless access points, and cameras, eliminating the need for separate power supplies or outlets for these devices.

The PoE+ ports on the WS-C3750E-48PD-EF can supply up to 30 watts of power per port, which is enough to power most PoE-enabled devices. This can help to simplify network deployments by reducing the need for additional power sources and cabling. It also reduces the total cost of ownership of the network, as devices can be deployed in areas where power outlets are not readily available.

The PoE+ ports also provide standard IEEE 802.3af and IEEE 802.3at power which allows the switch to provide power to devices that support either standard. Additionally, PoE+ ports also support Cisco's proprietary Cisco Discovery Protocol (CDP) and Link Layer Discovery Protocol (LLDP) which allows the switch to automatically detect and configure PoE-enabled devices connected to the switch.
