Connecting to the Stack's Backplane

Plug one end of the stack cable in the TX (right) port of the top unit and
the other end to the RX (left) port of the next unit. Repeat this step for
each unit in the stack. Form a simple chain starting at the TX port on the
top unit and ending at the RX port on the bottom unit (stacking up to
eight units). Finally, complete the stack connections by plugging one end
of a stack cable into the TX port on the bottom unit and the other end into
the RX port on the top unit.

Select the Master unit in the stack by pressing the push button in on only
one of the stacking modules. 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 stack
will not function.
