Before you add new switches to an existing Dell Force10 S-Series stack, pre-provision their stack unit numbers so the stack recognizes them and you can configure their ports ahead of time.
1. Provision the New Units on the Existing Stack
SSH to the current stack and, at the config prompt, enter one line per switch you’re adding:
stack-unit 2 provision S50V
stack-unit 3 provision S50VThe number is the unit number of the switch you’re introducing, and S50V is its model. Supported models include S25N, S25P, S25V, S50N, and S50V.
2. Renumber the New Switches
On each new switch, at the enable prompt, renumber it to match the unit number you provisioned:
stack-unit 0 renumber 2
stack-unit 1 renumber 33. Save the Configuration
Don’t forget to write out your config:
