MAGMA has discovered that some full length cards may have an interference fit issue on slot 3 of the ROBEN-3 product. The jack screw on the face plate of certain full length cards (e.g. AVID HDX) will interfere with the card guide slot of the chassis, preventing installation of the card. Product may be returned for repair by contacting MAGMA technical support as detailed below. Alternatively, if your full length card will not fit you may use a screwdriver to carefully remove the plastic card guide for slot 3 on the back wall of the chassis, which will provide additional clearance and allow for the card to fit. Once again this issue affects ONLY slot 3 of ROBEN-3 product when mated with SOME full length cards and is limited to a small number of early production serial numbers.
