you need a normal ATX Powersupply:
1 x 24 contacts and
2 x pci-e ( 8 contacts)
I used one with 1000 W singlerail.
I used the AVALON with IP 192.168.0.51 ( I wrote it on AVALON).
a) So if you also use your lan with 192.168.0.xxx , then you only have to:
1) connect the Powersupply with 3 the plugs with the AVALON
2) Connect the AVALON with your LAN ( there is also a WLAN inside. I did never use it, because it seems to make problems at other users)
3) Switch it on
4) with the settings the AVALON is working for me :-)
5) take you PC and use your browser. Type in your browser: 192.168.0.51
6) now you are on the AVALON. I didn´t set a Password, so klick throu.
7) write your bitcoinpool datas to the Settings, restart ( take the menue) ( use "Failover" .With this Option I never had any Problems. "Balance" made Problems)
--> it is all ok.b) if not:
1) connect the Powersupply with 3 the plugs with the AVALON
2) connect your pc via LAN D I R E CT to the avalon ( no other connecitons)
3) start AVALON
4) start your PC ( use : get IP from .. ; no fixed IP)
5) go to your AVALON ( using the browser of your PC)
6) set the IP like you wish it.
7) shut down AVALON and PC
all the same from a)2) above
