To count the ports on the twisted pair models, include the two 10/100/
1000Base-T ports along with the 10/100Base-TX ports, but not the SFP
slots. For example, a stack of AT-8100S/24 Switches could have up to
eight units:
8 switches x 26 ports = 208 ports
To count the ports on the fiber optic models, include the fiber optic, 10/
100Base-TX, and 10/100/1000Base-T ports, but not the SFP slots. For
example, a stack of AT-8100S/24F-LC Switches could have eights units:
8 switches x 26 ports = 208 ports
Choosing a Site The switches of a stack should be installed in a standard 19-inch
equipment rack and not more than one meter apart, the length of the
stacking cable. The end switches cannot be more than one meter apart if
you want to create the duplex-ring topology, shown in Figure 17.
Figure 17. Switches in an Equipment Rack
You may place the switches side-by-side on a table or desktop, as shown
in Figure 18. However, you will not be able to create the duplex-ring
topology with a stack of three or more switches, because the distance
between the end switches will be more than one meter.
