After running the blades for 2-3 weeks, they both started to slow down to like 1-4 GHS. I don't know how or why. I tried resetting the PSU but it didn't help. The blades heatsinks are pretty cool not like before. So I decided to factory reset one of them and see if it will fix it. I shorted 2 and 3 with a screwdriver and then the green LED start to blink. Then I tried to go to the config page http://192.168.1.254:8000 but it didn't work. Then I realized that the blade is not turning on anymore. I tried turning off the PSU and switching different calbe, it didn't help.
Please help me out here.
PS. I have the other one running, but it's still slow.
