Assign Unit Numbers to Units in an S-Series Stack
Each unit in the stack has a stack number that is either assigned by you or FTOS. Units are numbered from
0 to 11, however, only six (6) S4810 or S4820T units can be stacked. Stack numbers are stored in NVRAM
and are preserved upon reload.
Create a Virtual Stack Unit on an S-Series Stack
Use virtual stack units to configure ports on the stack before adding a new unit.
