I'm pretty sure this is a bug in the advanced management module, I know the QS20 blades aren't well supported at this point.
In any case, I put in three of the QS20 blades with drives and powered them on, hoping one of them would just boot up and get a DHCP address... no such luck.
I took a glance at the power usage graph and immediately powered off the blades...
Like I said, I'm pretty sure this is a bug... I'm running this off a single 110 volt circuit, wouldn't it trip the fuse if this were real?
