Hi

I see the failed fan on 2b on the system log. These fans are utilized as cooling fans and you have multiple back ups fans to cool off the Thunder 930. The fan failure will not impose system failures as you have adequate cooling fans to sustain the heat. These fans are hot swappable so my suggestion is to contact A10 support and they will RMA a new fan for your system. No system or operation interruption when you change the failed fan. Good luck!

So to replace a fan, remove the 2 sets of screw that holds the fan to the chassis. Once removed, the fan module will slide out and you can replace it with the new fan. As I mentioned before these are hot-swappable so the A10 device does not have to be powered down to change the fan.
