1. A module to be mounted on a backplane for transferring power and furnishing communications between the module and the backplane, the module comprising:

  • a first magnetic E-core for transferring power between the module and the backplane, the first magnetic E-core having a center leg and first and second outer legs, the center leg and the first and second outer legs of the first magnetic E-core being joined at a first end thereof and being mounted with a second end thereof adjacent an end of the module, the module having at least one wound coil encircling at least one of the center leg and the first and second outer legs of the first magnetic E-core, the second end of the first magnetic E-core having a protective sheet or layer thereover, the first magnetic E-core to meet with a second magnetic E-core having a center leg and first and second outer legs, the center leg and the first and second outer legs of the second magnetic E-core being joined at one end thereof and being mounted with a second end thereof extending into openings in the backplane, the backplane having a printed coil encircling at least one of the center leg and the first and second outer legs of the second magnetic E-core; and

    a first magnetic I-core for furnishing communication between the module and the backplane, the first magnetic I-core having an end thereof mounted adjacent the end of the module, the module having at least one wound coil encircling the first magnetic I-core, the first magnetic I-core to meet with a second magnetic I-core mounted with an end thereof extending into an opening in the backplane, the backplane having a printed coil encircling the second magnetic I-core;

    the module being configured so that the second end of each leg of the first magnetic E-core is aligned with the corresponding leg of the second magnetic E-core and the end of the first magnetic I-core is adjacent the end of the second magnetic I-core when the module is mounted to the backplane, wherein the first magnetic E-core is loaded to protrude from a mounting plane of the module, and the first magnetic I-core is positively mounted to a circuit board in the module.
