Managing S-Series Switches in a Stack
You can use Node Manager to manage the stacking of S-Series switches, which enables up to three
switches to act as a single managed switch. Of the various S-Series models, only the S2410 models do not
stack. Also, the S50 model stacks only with the same model. All other models — S50V, S25P, S50N, etc.
— can coexist in the same stack.
The master switch, called the management unit, manages the stack. For details on the algorithm that
determines which is the management unit, see the Stacking chapter in the SFTOS Configuration Guide.
Each switch has a unique switch ID/unit number that the management unit uses to identify it as a stack
member, just as if it were a numbered line card in a large switch. Likewise, Node Manager identifies ports
partly by their switch ID. For example, port 2/0/30 identifies port 30 in member unit 2 (SFTOS uses the
middle number to identify slot numbers, but does not use it for the S50.)
S50 switches can be pre-provisioned. You can logically add, delete, or renumber a member unit in Node
Manager. For stacking details not included in this section, see the stacking chapters in the SFTOS CLI and
configuration guides, which are on the CD-ROM that accompanies the S50.
You can perform these switch management activities with Node Manager:
• Adding S-Series Switches to a Stack
• Deleting Member Switches from an S50 Stack on page 91
• Renumbering a Switch Member in an S50 Stack on page 92
• Setting Priority on a Switch Member in an S50 Stack on page 92
Adding S-Series Switches to a Stack
You can use Node Manager to pre-configure the management unit of an S-Series stack with a new stack
member. Unassigned members are those that only exist in the software but do not yet exist physically in
the stack.
To add a member switch in Node Manager:
Step Task
1 Right-click the graphic of any empty “slot” in the stack. Node Manager indicates these by displaying a
picture of a blank panel.
