Choosing the Right Access Point
Figure 4
Differences between the AP 3600 and AP 3500 Access Points
The internal antenna version of AP 3600 and AP 3500 is almost identical in physical appearance with
the exception of the LED which is slightly larger and more oval on the AP 3600. The AP 3500 has a
square LED (allows for visual identification).
Figure 5
From a side view, the AP 3600 is slightly thicker when compared to the AP 3500. The thicker size allows
for additional radio support and printed circuit board area, as well as modularity for future capabilities.
While the AP 3600 has a little more depth, this AP is completely backward compatible with the mounting
brackets for the existing Cisco Aironet 1040, 1140, 1260 and 3500 Series Access Points.
