Table 19   SuperStack 4 Switch 5500 Support for XRN Distributed Fabric
Stacking Switch 5500 Units
1 Ensure that the Switch units that you wish to interconnect have the latest 
software agent installed. You can use the display version 
command to check this.
2 Enable the ‘up port’ and the ‘down port’ on each Switch (see Table 19
) to 
operate in Fabric mode using the following CLI command. From the 
System View enter fabric-port gigabitethernet 1/0/51 
enable, for example.
