Abstract: A rackmount chassis includes removable supports that provide interior support for blades having mounting edge-to-mounting edge dimensions that are less than the full chassis width. The removable supports are mounted on parallel support plates that span the full width of the chassis. Each removable support supports an edge of at least one blade installed into the rackmount chassis.
