Power over Ethernet
(Supported Models: TI-PG541i, TI-PG102i & TI-RP262i)
The main advantage of PoE is that it can make installing a network easier. The selection
of a location for a network device is often limited by whether there is a power source
nearby. This constraint limits equipment placement or requires the added time and cost
of having additional electrical sources installed. However, with PoE, you can install PoE
compatible devices wherever they are needed without having to worry about whether
there is power source nearby.
Power Sourcing Equipment (PSE)
A device that provides PoE to other network devices is referred to as power sourcing
equipment (PSE). The Gigabit Web Smart PoE+ Switch is a PSE device which provides DC
power to the network cable and functions as a central power source for other network
devices.
Powered Device (PD)
A device that receives power from a PSE device is called a powered device (PD).
Examples include wireless access points, IP phones, webcams, and even other Ethernet
switches.
PD Classes PDs are grouped into five classes. The classes are based on the amount of
power that PDs require. The Gigabit Web Smart PoE+ Switch supports all five classes.
