FAQ
Is my device still under warranty?
The duration depends on the manufacturer and the date of purchase. Have your invoice and serial number ready, then submit a request via the form for confirmation.
What if the breakdown isn't covered?
We issue a precise quote (parts, labor, logistics). You decide whether or not to accept it.
Can I only send the hashboard/PSU?
Yes, if the support team instructs you to. Follow the packaging instructions exactly and mention the RMA.
Will I lose my settings?
A reset may be necessary. Back up your configuration (pools, IP) before sending.
