Chapter 7. Physical Characteristics of the 7100 Series
This chapter provides the physical characteristics for the 7100 series of external devices. The following
information can help you plan for your external devices. You need only do physical planning for the
devices you have ordered.
Note: Footprints are not drawn to scale. Where a footprint is shown, the figure represents a top view of
the device.
