Stacking

You can connect up to four 20-port SANbox 5602 switches together through the
10-Gbps ports, thus preserving the user ports for devices. This is called stacking.
The following 2-, 3-, and 4-switch stacking configurations are recommended for
best performance and redundancy. Each 10-Gbps port contributes 1 GB of
bandwidth between chassis with one chassis hop between any two ports. A
two-switch stack uses two 3-inch XPAK switch stacking cables as shown in
Figure 3-1. 32 1-Gbps/2-Gbps ports are available for devices.
