	Folks,

		You can buy a power over ethernet power supply from Motorola intended for 
the Motoral canopy for about $15.00 and make it work with the Soekris. You 
have to wire the cable as follows:

		Cross one end:

		1 to 3
		2 to 6 == Data cross for connecting to computer. Dont cross these if going 
to a hub

		4 to 8 ==> Power cross (Soekris gets power on pins 4 and 8)
		5 to 7 ==> Probably not needed, can be left out but there is power on these 
as well using the Motoral power supply.

		Motorola has the + and - reverse of Soekris the power comes in on 4 and 8 
and 5 and 7. I dont think pins 5 and 7 on the soekris do anything so you 
prob. dont have to cross those 2 pins but to be safe we do.

		This runs at 24 volts and powers the soekris through eth0 fine.

		We buy in bulk and would prob. be willing to order extras for those who 
wanted them and include the proper cable for 16.00 each.
