A method and apparatus for automatically verifying whether a network interface is receiving frame data properly. A first magnetic member is disposed within the interior cavity and adjacent to a surface of the interior cavity that is immediately opposite the exterior drive surface. The support structure is extendable from a storage position to a first extended position suitable for supporting the platform structure at a first height and a second extended position suitable for supporting the platform structure at a second height that is greater than the first height. The conductive material layer includes a first section separated from substrate by the second portion of the dielectric layer.
