Abstract/Summary

Cisco currently designs a variety of custom chassis for different types of servers, routers, and switches. Our senior design project aims to reduce the number of custom chassis Cisco develops by standardizing the perimeter mounting locations for the printed circuit board assembly on the chassis. The purpose of this report is to document our selected project direction and support the decisions with appropriate evidence. In addition to research on the customer’s needs, the product, and the technical background used to understand the project scope, our group has come up with a way to analyze and compare mounting locations for various designs. Our team focused on the Quake chassis family to compare new designs with existing tooling and created a guideline for future standardization. We completed a MATLAB script that compares existing and future chassis hole locations to tooling locations in order to determine the best tooling set for a given chassis. We also made a document that analyzes hole locations based on the different depths of the Quake chassis families. We hope that our research and analysis will become a future guideline for designers to implement common features for PCBA mounting locations and chassis interfaces.
