Frequently Asked Questions
Common Questions
Can a failed network controller be repaired?
Often, where the fault is in the power stages or interfaces. Assessment confirms the failed part and whether it can be replaced.
Do you keep configuration data?
Repair works on the hardware. Back up configuration where you can; firmware recovery attempts to preserve data but cannot guarantee it.
Have a Failed Controller or Appliance?
Describe the equipment and the fault. Sinsal will confirm whether it is a fit for diagnostics and repair before any work begins.
