One of the four LED indicators is off on my iBeLink DM11G machine. Find attached the screenshot from the miner. It shows that it is working and it's hashrate is included into total hashrate. But look at the Active map column, it shows zero.
Is it normal? I think it is inactive. Waiting for your reply.
When you say the LED indicator is off, do you mean it is not lit? Not red or blue? It could be that the LED has burned itself out. From the screenshot, all the readings are indicating your hardware is still good. You are detecting 4 blades, 16 chips each and running at 600 PLL and low H/W.
The Active Map values do vary and will sometimes show a 0. This is normal as it will change again. If it stays at 0 for a very long period of time, then you will need to restart the miner.
