Guide rail and cam system with integrated connector for removable transceiver

A signal sequencing method for plugging an electronic interface module into an electrical connector in a computer system, the electrical connector mounted on a circuit board within a computer enclosure and having a plurality of electrical contacts, the module having a body elongated along an axis and having a plurality of faces, the electrical contact pads disposed in a planar array on one of the faces, the electrical contact pads elongated in a direction parallel to the axis and laterally arrayed in at least one row oriented perpendicularly to the axis, the method comprising the steps of:

• sliding said module into engagement with said electrical connector in a direction along said axis until a first electrical contact of said electrical connector makes contact with a first contact pad in one of said rows;
• and
• continuing to slide said module into engagement with said electrical connector until a second electrical contact of said electrical connector makes contact with a second contact pad laterally spaced from said first contact pad in said one of said rows while said first electrical contact remains in contact with said first contact pad.

A method for removably coupling electrical ground potential of a computer system to electrical ground potential of a module removably engageable with an electrical connector of said computer system, said electrical connector including a spring clip and a plurality of electrical contacts, said spring clip coupled to said ground potential of said computer system, the method comprising the steps of:

• sliding said module into engagement with said electrical connector in a direction along said axis until a portion of said module makes electrical and mechanical contact with said spring clip and until at least some of said electrical contacts of said electrical connector make contact with electrical contacts of said module;
• whereby electrical ground potential of said computer system is coupled to electrical ground potential of said module.
