Connecting Switches in a Stack
3
To connect up to eight switches in a stack, perform the following steps:
1. Plug one end of the stack cable (ordered separately) in the Down (right) port of
the top unit.
2. Plug the other end of the stack cable into the Up (left) port of the next unit.
3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting at
the Down port on the top unit and ending at the Up port on the bottom unit
(stacking up to 8 units).
4. (Optional) To form a wrap-around topology, plug one end of a stack cable into
the Down port on the bottom unit and the other end into the Up port on the top
unit.

5. Select the Master unit in the stack by pressing the Master button in on only one
switch unit. Only one switch in the stack can operate as the Master, all other
units operate in slave mode. If more than one switch in the stack is selected as
Master, or if no switches are selected, the system will select the unit with the
lowest MAC address as the Master.
