Claim 16:
17. A method for mounting a lightpipe in a module, the method comprising:
placing a combination of standoff and LED onto the surface of a printed circuit board assembly (PCBA), wherein
the combination of standoff and LED comprises a surface mount standoff and LED,
the LED is located at a base surface of the surface mount standoff, ensuring that the LED is positioned under a cylindrical cavity defined by a cylindrical wall of the surface mount standoff, the cylindrical wall extending from a base at one end of the cylindrical wall to another end of the cylindrical wall defining a circular opening, wherein the one end of the cylindrical wall surrounds the LED, and
points of the LED for making electrical contact with the PCBA are surrounded by and exposed to the PCBA through the base surface;

attaching the surface mount standoff and LED to the PCBA as a single component to secure the surface mount standoff and LED in place and to provide power to the LED;
disposing a cylindrical light absorbing end of a lightpipe through the circular opening and into the cylindrical cavity of the surface mount standoff;
aligning and disposing a light emitting end of the lightpipe with and through a hole in a faceplate of a module enclosure; and
securing the cylindrical light absorbing end of the lightpipe in the cylindrical cavity of the surface mount standoff such that the LED is aligned with the cylindrical light absorbing end of the lightpipe within the cylindrical cavity.
