Stacking | 857
Usage Notes:
• Stacking is not supported on Fibre Channel ports.
• If you use a Fibre Channel module in an S5000 switch, stacking is not supported on Ethernet ports.
• If you use three or more S5000 units in a stack, you can connect up to a maximum of eight 10GbE
ports or two 40GbE ports in links between peer switches.
• If you use only two S5000 units in a stack, you can connect up to four 40GbE ports in links
between the two switches.
Figure 48-4. S5000 Stack-Group Assignments
Stack groups 0 through 11 consist of four 10GbE ports; stack groups 12 to 15 consist of one 40G port as
follows:
