1
Ensure that your Switches are correctly installed and that
you have the correct number of Matrix Cables for your con-
figuration. We recommend that the bottom unit in your
stack is the one that contains the Matrix Module.
2
Working first with the Switch that contains the Matrix Mod-
ule, attach a Matrix Cable to one of the ports on the Matrix
Module. Connect the other end of that cable to the matrix
port on the same unit. For your stack to operate as one
unit, you must do this.
3
Connect each of the remaining cables between the ports on
the Matrix Module and the matrix port on each unit.
4
Connect your power cord and power-up the stack.
