Examples of Stacking Configurations
Here are some sample stacking configurations for 220 series switches.
Note
In each example, the stacks consist of 48-port switches and connections are made through
SFP+ ports 49 and 50.
If you are stacking 24-port switches, make the connections through SFP+ ports 25 and 26.
If you are stacking 12-port switches, make the connections through SFP+ ports 13 and 14.
Stacked Switches in a Single Rack
This example shows a stack of four switches in a single rack.
The stack manager, installed at the top of the rack, is connected to the management console. Each
switch in the stack is connected to two other switches by 10GbE stacking cables inserted into the
switches' 10 GbE SFP+ ports. (See
Figure 44: Cable Connections for Four Stacked Switches in the Same Rack
lists the recommended order for connecting the stacking ports in this example.
