Power over

Ethernet

Power over Ethernet (PoE) technology describes a system to transmit electrical power, along with data, to remote devices over standard
twisted-pair cable in an Ethernet network. This technology is useful for powering IP telephones, wireless LAN access points, network cameras,
remote network switches, embedded computers, and other appliances where it would be inconvenient, expensive, or infeasible to supply power
separately. The technology is somewhat comparable to POTS telephones, which also receive power and data (although analog) through the same
cable. It works with an unmodified Ethernet cabling infrastructure.

PSE

Power Sourcing Equipment (PSE) is a device (switch or hub for instance)
that will provide power in a PoE setup. Maximum allowed continuous
output power per such device in IEEE 802.3af is 15.40W.

PD

A Powered Device (PD) is a device powered by a PSE and thus consumes
energy. Examples include wireless access points etc.. The IEEE 802.3af
standard specifies a maximum power usage of 12.95W.

TL-SF1008P

8-port 10/100M Desktop PoE Switch

TL-SF1008P is an 8 10/100M ports unmanaged switch that requires no
configuration and provides 4 PoE (Power over Ethernet) ports. It can
automatically detect and supply power with all IEEE 802.3af compliant
Powered Devices (PDs). In this situation, the electrical power is
transmitted along with data in one single cable allowing you to expand
your network where there are no power lines or outlets, where you wish
to fix devices such as APs, IP Cameras or IP Phones, etc.
