Greetings, My first post !! Thanks all !!
I have 5 total Antminers all running at my office. 2X Antminers S7-LN, 2X Antminers S5 and 1 Antminer S3. All were running perfectly for weeks at my office. Over the past weekend, they all stopped mining. I VPN'd into my office and was able to connect to them all, but they all showed DEAD under mining status so I rebooted them all. None of them came back on the network after the reboot. I couldn't connect to them with a browser and was unable to ping any of there address. I spoke to our IT department and long story short, there was an issue with a Cisco switch so they rebooted the switch and they said everything should be good. I rebooted the S7-LN miners and had a red LED and was unable to connected to it. I tested the Ethernet cable going to it with a laptop and was able to get online, no problems. Both S7-LN have the same issue. I also rebooted the remaining miners and none of them mine. Seems like same issue. I factory defaulted both S7-LNs and still same issue, red LED.
Does anybody know what could be causing this ? Is there a known issue with Cisco switches working with Antminers ? Any help would be greatly appreciated !!!
Thanks,
Mike
okay first determine your miners were not killed off some how and won't work any where at all.
I.e. pick an s7-ln bring it to your house and see if it works.
If it works and all your other miners work in your house.
you can try buying this
https://www.amazon.com/gp/product/B003CFATSS/ref=oh_aui_detailpage_o00_s00?cisco switch ------------ your office eth wire ------------- >> dsl router above to eight eth out ports plug in a laptop and your miners
you should be in a 192.168.1.1 to 192.168.1.254 sub net work
load advanced ip in the lap top.
scan the 192.168.1.1 to 192.168.1.254 sub net work you should find the miners and the laptop .
note may not work depends on wtf your it guys did.
