Computer network device and method of assembly

1. A computer network device, comprising:

a subassembly including

a support plate having a first edge;

a standoff extending from a surface of the support plate;

a printed circuit board (PCB) secured to the standoff and spaced from the support plate;

an electromechanical connector secured to the PCB;

an electromagnetic interference (EMI) cage secured to the PCB and surrounding the connector; and

an EMI gasket engaging the EMI cage adjacent a first end thereof;

an enclosure including a bezel and an opening in the bezel, the enclosure containing the subassembly, the opening receiving the first end of the EMI cage such that the EMI gasket abuts an inside surface of the bezel; and

a guiding and retaining member secured to an inside surface of a first wall of the enclosure and spaced from the bezel, a space between the bezel and the guiding and retaining member defining a subassembly receiving space;

wherein the guiding and retaining member includes a first surface that faces the bezel and a second surface including a slope, and the slope is configured to engage and guide the support plate first edge as the subassembly is inserted into the subassembly receiving space, and the first surface is configured to abut the support plate first edge to retain the subassembly within the subassembly receiving space.

2. The computer network device of claim 1 , wherein the device is a switch, a host system, a server, a peripheral, an input/output subsystem, a bridge, a hub or a router.

3. The computer network device of claim 1 , wherein the first surface of the guiding and retaining member includes an indentation configured to receive the support plate first edge.

4. A method of assembling a computer network device, the method comprising:

assembling a subassembly by

securing a printed circuit board (PCB) to a support plate, the support plate including a first edge;

securing an electromechanical connector the PCB;

securing an electromagnetic interference (EMI) cage to the PCB such that it surrounds the connector; and

securing an EMI gasket to the EMI cage adjacent a first end thereof;

securing a guiding and retaining member to an inside surface of a first wall of an enclosure, the enclosure including a bezel and an opening in the bezel, the guiding and retaining member being spaced from the bezel, a space between the bezel and the guiding and retaining member defining a subassembly receiving space, the guiding and retaining member including a first surface that faces the bezel and a second surface including a slope;

positioning the subassembly partially within the subassembly receiving space such that the opening in the bezel receives the first end of the EMI cage and the first edge of the support plate rests on the slope of the guiding and retaining member second surface; and

applying a force to the subassembly to urge the subassembly into the subassembly receiving space such that the EMI gasket abuts an inside surface of the bezel and the first surface of the guiding and retaining member abuts the support plate first edge to retain the subassembly within the subassembly receiving space;

wherein the slope engages and guides the support plate first edge as the subassembly is inserted into the subassembly receiving space.

5. The method of claim 4 , wherein the device is a switch, a host system, a server, a peripheral, an input/output subsystem, a bridge, a hub or a router.

6. The method of claim 4 , wherein securing the PCB to the support plate comprises securing the PCB to a standoff extending from a surface of a support plate such that the PCB is spaced from the support plate.
