2.10 Making Stack Connection
To expand the number of the connected users, the switch provides two 5G stack ports for cascading more than
one switch together. Up to five switches are allowed to cascade as one single switch stack that is able to

The stack ports, SA and SB locate on the rear panel as illustrated below:
To connect two switches via stacking, use the stack cable which is bundled in product package. Connect one
end to the SA port of one switch and connect the other end to the SB port of the other switch as shown below:
