Power over Ethernet (PoE)

The QuickStart + W5200 board can optionally be powered over an Ethernet connection by a 3rd party
daughter board, the Silvertel Ag9050. This PoE solution complies with the IEEE 802.3af standard for
extracting power from Ethernet. In order for PoE to work, your physical network needs to have power
injected into the transmission medium as per the standard's specification. The majority of networks do
not natively support this feature as it requires the use of special hardware.
The header of 10 pins at the bottom of the WIZnet W5200 board, pictured above, is for use with the
Silvertel Ag9050. To enable PoE, simply solder the Silvertel Ag9050 daughter board into this header.
The daughter board can only be inserted one direction as the header is keyed by pin orientation. Once
you have correctly attached the PoE daughterboard, your QuickStart + W5200 board can be powered and
communicate through a single connection – the Ethernet cable.
Network Configuration Notice
Parallax cannot assist in home router configuration due to the wide variety of routers, configuration
options, and network topologies. Many of the downloadable demonstration programs, including the base
web server software for the W5200, assume the most common network configuration and configures the
W5200 to work with most home networks, as shown on page 4. The W5200 can be configured manually,
but additional knowledge of the Propeller, networking protocols, and your network's configuration is
required.
