Hello again,
When putting my 2big network 2 to "sleep" with the "NAS Standby WOL" option on GUI, the fan keeps working 100%.
So, all lights go off (except for the Ethernet port); and the NAS IP becomes unresponsive; all as expected. But the fan is always working, never stops. Tried waiting 5-10 minutes.
Sending magic packet awakes it, which is good :) And after boot, during normal operation, the fan keeps idle.
What can the problem be?
