1.1.7 PoE

The Switch is a Power Sourcing Equipment (PSE) because it provides a source of power through its
Ethernet ports. Each device that receives power through an Ethernet port is a Powered Device (PD).
The Switch can adjust the power supplied to each PD according to the PoE standard the PD supports.
PoE standards are:
• IEEE 802.3af Power over Ethernet (PoE)
• IEEE 802.3at Power over Ethernet (PoE) +
• IEEE 802.3bt Power over Ethernet (PoE) ++
The following table describes the PoE features of the Switch by model.
