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.
