Using the Grid I/O Boards significantly reduces the cabling effort between DKM Modular KVM Matrix Switches. In a setup based on two matrices, the grid I/O boards can be directly connected via the fiber port. In a setup using multiple matrices, the second fiber port on each grid I/O board enables you to set up a ring topology with four grid connections on each port. Each matrix connects to two other matrices.
