Important Points to Remember
• YYou may stack up to eight S25/S50 systems in combination.
• You may stack up to 12 S60 systems
• You may stack up to 3 S4810 systems
• You may not stack different S-Series systems together (except the S25/S50)
• You may not connect 12G and 24G stack ports.
• All stack units must have the same version of FTOS.
S-Series Stacking Installation Tasks
• Create an S-Series Stack on page 1026
• Add a Unit to an S-Series Stack on page 1029
• Remove a Unit from an S-Series Stack on page 1032
• Merge Two S-Series Stacks on page 1034
• Split an S-Series Stack on page 1035
Create an S-Series Stack
Stacking modules are pluggable units in the back of the unit that switch traffic between units in a stack.
Units are connected using bi-directional stacking cables; if you stacking modules have two ports, it does
not matter if you connect port A to B, or A to A, or B to B. Install stacking modules before powering the
unit. If you install a stacking module while the unit is online, FTOS does not register the new hardware; in
this case, you must reload the unit.
