We just received a UC1 for Unity Connection 1.2, and need it installed and operational tomorrow, so out of the box I let it do its thing.
Don't let it do its thing, use the platform disk instead. None of the drives were properly setup and the raid1 was not configured. I just wasted a good 2 hours of my time getting this up to date and ready to install UC when I got the notice that there isnt enough space on G drive to install Unity.
So for all those who are getting a 7825 H3, keep that in mind, it may save you some time. :)
