The Fabric Details window does not include a scroll bar in the large icon view of the Chassis & Links perspective. The scroll bar should always be displayed when the image is larger than the Fabric Details window. The scroll bar enables you to view all the nodes in a large partition.
Workaround: While in the Chassis & Links perspective, change from the large icon view to the small icon view. The scroll bar is displayed. Then change back to the large icon view. The scroll bar stays displayed.
Changing to the Nodes & Routes perspective from the large icon Chassis & Links perspective also displays the scroll bar. However, when you change back to the large icon Chassis & Links perspective, the scroll bar is no longer available.
