Stacking
Stacking is supported on the following platforms: s (S50/S25),
Stacking is supported on the S4810 platform with FTOS version 8.3.7.1, version 8.3.10.2 and newer.
Using the FTOS stacking feature, multiple S-Series switch units can be interconnected with dedicated
stacking ports or front end user ports. (The S50, S55, and S60 use dedicated stacking ports; the S4810 uses
front end user ports for stacking.) The stack becomes manageable as a single switch through the stack
management unit.

S-Series Stacking Overview
An S-Series stack is analogous to an E-Series or C-Series system with redundant RPMs and multiple line
cards. FTOS elects a management (master) unit, a standby unit, and all other units are member units.
Note: The S4810 commands accept Unit ID numbers 0-11, though the S4810 supports stacking up to 3
units only with FTOS version 8.3.7.1 and version 8.3.10.2. The S4810 supports stacking up to 6 units on
FTOS version 8.3.12.0. The S55 supports stacking up to 8 units.
Note: Stacking S55 and S60 units with other devices is not supported.
