Figure 39-7. Accessing Non-Master Units on a Stack via the Console Port
Important Points to Remember
• You may stack up to twelve S55 systems.
• You may not stack a combination of S-Series models. S55 systems can only stack with other S55
systems.
• All stack units must have the same version of FTOS.
• Insert S55 stacking modules in the lower optional module slot (slot 0) only. The upper optional module
slot does not support stacking modules.
S-Series Stacking Installation Tasks
• Create an S-Series Stack
• Add a Unit to an S-Series Stack
• Remove a Unit from an S-Series Stack
• Merge Two S-Series Stacks
• Split an S-Series Stack
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.
