3.1.2 PoE
The Zyxel Device 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). A
Powered Device (PD) is a device that receives power through PoE, such as an IP camera, a wireless
router, an IP telephone or a general outdoor router.
Note: Do not connect the Zyxel Device PoE+ port to a non-Powered Device. If you need to
connect a non-Powered Device to the Zyxel Device PoE+ port, make sure to disable
PoE in Network > Interface > Port first.
The following example figure shows a Zyxel Device supplying PoE (Power over Ethernet) to PDs that are
not within reach of a power outlet.
Figure 29 PoE Application
The Zyxel Device 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+)
The following table describes the PoE features of the Zyxel Device by PoE standard.
