I've got two units which won't go through the startup sequence; the 4 right most lights stay solid. Does anyone know what that means when those lights stay on? My other 15 units work perfectly.
Don't plug in the usb cable, if the 7th LED keep blinking that mean the board are not cool enough.
When that happen just hold the board near an AC to cool it for about a minute then plug it in and let it complete the boot sequence and all LED are off before starting the miner software.
Tried that but no luck. Thanks for the suggestion though.
