All my 3 Antminers (december batch with PCI-E connectors Bitmaintech V1.2 2013/12/4) claim that network cable is unplugged. I tried to reset them, used different IP conf. connected to router.
Does it need crossed over cable?
Network seems to try to identify itself after power on but then goes back to network cable unplugged. Cables checked with cable tester.
I see R24 PWR red diode blinking and C31 green diode blinking
are the on the right ip subnet? (if your router is 192.168.0.1, they should be 192.168.0.XXX where XXX>99)
make sure all 3 dont have the same IP address.
also, if you are using 'DHCP client' for WAN, switch it to 'static address' and
MAKE SURE YOU USE DNS SERVER 8.8.8.8
