How To Specify a Chassis; Design Steps
The links provide many of the steps that need to be followed to spec out an equipment chassis so that it adheres to the standards required to meet the requirements of the design. Each page link has a description of the task, and some number of equipment manufacturers links. In some cases a particular component may not be required to complete the chassis design.
An Equipment chassis design should start with either a maximum chassis size, a particular card form factor or a form factor which meets the required bus through-put rate.
