Re: UP2000+ Problems

Jon...

the only power supply i have here is a 300W. hardly powerful enough to
power even 1 cpu on that board. i did read the power requirements in the
user manual. if i were going to buy one i would sink $50 or more in it,
plus i would have to obtain an adapter for the J28 connector. with tax
and shipping, i would guess $80 or more.

another consideration is the cheaper power supplies are usually atx for
a tower configuration. i have the powerrac server enclosure. the
configuration is a bit different. including setting jumpers for
tower/server configurations. 

as matt mentioned, a couple of people in the alpha IRC channel thought
of the power supply, but others had mentioned possibly buggy firmware.
that being the cheapest route was what i wanted to address first. 

i am doing as much testing as i can, without spending a lot of money,
before i put it up on ebay for sale. 

thanks for your input...
