1.1.2 Web Configurator Surveillance Mode
Aside from the Web Configurator in Standard mode, you can switch to Surveillance mode that is
specifically designed for configuring and managing PoE devices like IP cameras (
Chapter 45 on page
322 ).
1.1.3 PoE
The Switch is a Power Sourcing Equipment (PSE) because it provides a source of power via 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) Plus
• IEEE 802.3bt 4PPoE Type 3
The following table describes the PoE features of the Switch by model.
1.2 Example Applications
This section shows a few examples of using the Switch in various network environments. Note that the
Switch in the figure is just an example Switch and not your actual Switch.
1.2.1 PoE Example Application
The following example figure shows a Switch supplying PoE (Power over Ethernet) to Powered Devices
(PDs) such as an IP camera, a wireless router, an IP telephone and a general outdoor router that are not
within reach of a power outlet.
