1.1.3  ZON Utility
With its built-in Web Configurator, including the Neighbor Management feature (Section 13.1 on page 
106), viewing, managing and configuring the Switch and its neighboring devices is simplified.
In addition, Zyxel offers a proprietary software program called Zyxel One Network (ZON) Utility, it is a 
utility tool that assists you to set up and maintain network devices in a more simple and efficient way. 
You can download the ZON Utility at www.zyxel.com and install it on a PC (Windows operation system). 
For more information on ZON Utility see Section 4.3 on page 53.
1.1.4  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 PoE standard.
