Hi Songvat,

Been waiting to see what other folks might know about the fatal error, but no response.

I hope by now you have been in contact with your distribtor for a fix or the Small Business Support Center (SBSC).

If not here is the contact information for SBSC. Luckily the switch is covered by a good warranty,

Sorry for this hassle, but a cursory look at the capture indicates at this statge , as you suspect a bad switch.

Wish i could be more helpful,

regards Dave
