Were these all on a backplane at the same time when they died? What happened before they went "poof"?
According to OPs other post yes they were all in a backplane, not sure why numbers don't match up as there we 8 in the backplane maybe sold one already?:
"This same incident just happened to me too.
I just lost 8 blades - Poofff gone. All running on a backplane sitting on electrical grade GP03 fiberglass.... Was running a 750 PSU and then everything showed Zero for speed on my mining pool. I didn't have any replacement fuses, nor do I know where to get them.
I'm still down Sad - Is anyone still buying units like this? Could use the capital to get new miners. I have five (5) Green Back BE V. 2.01 and three (3) Blue Back BE V. 2.01's for sale.
All are in perfect condition less the fuse assembly. Look brand new..

I was able to get one unit running perfectly by removing the fuse, cleaning the contacts and electrical taping over the fuse."
