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.
Connecting a Stacking Cable to a Port
Stacking cables are used to form physical connections between the switches in a stack.
To connect a stacking cable, follow these steps:
1 Align the cable connector with the stacking port connector on the first switch.
2 Firmly press the cable connector into place on the mating stacking port connector.
3 Repeat steps 1 and 2 to connect the cable to the second switch.
Repeat these steps to connect all of the switches in the stack.
Connecting Your Stack to the Management Network
Connect your management console to the Ethernet management port on the switch that will become
the stack manager. If you plan to configure redundancy, we recommend connecting to the console ports
of all switches in the stack that will function as standby units.
