Stacking
You can connect up to six SANbox 5802V switches together through the XPAK 
ports, thus preserving the SFP ports for devices. This is called stacking. The 
following 2-, 3-, 4-, 5-, and 6-switch stacking configurations are recommended for 
best performance and redundancy. Each XPAK port at 10-Gbps contributes 1 GB 
of bandwidth between chassis with one chassis hop between any two ports. 
Figure 3-1 shows a two-switch stack of model 5802V switches using two 3-inch 
XPAK switch stacking cables. Forty SFP ports are available for devices.

Figure 3-2 shows a three-switch stack of SANbox 5802V switches using two 
3-inch and one 9-inch XPAK switch stacking cables. Sixty SFP ports are available 
for devices.
