We just received information from Atcom that the latest batch of their AX-400P cards has a problem that might cause a short circuit. This is an excerpt from the letter:

Today, we found a serious issue with the AX-400P new design we shipped you last time, the issue relates to potential short circuit in the screw on the bottom of the board.

When the short circuit happen, the board may be damaged, you can see there is a broken black line in the circuit of the PCB. The card will still be able to use in this case, but there is potential danger since the circuit exposures.

If you have purchased this type of card recently you should contact your supplier and ask how to find out if your card is affected as well as their policy relating to this problem.
