Speed in RPM
The following example shows how to configure two new S4810 or S4820T switches for stacking using
10G ports.
S4810-1(conf)#stack-unit 0 stack-group 0
Setting ports Te 0/0 Te 0/1 Te 0/2 Te 0/3 as stack group will make their interface configs obsolete after
a reload.
[confirm yes/no]:yes
S4810-2(conf)#stack-unit 0 stack-group 0
Setting ports Te 0/0 Te 0/1 Te 0/2 Te 0/3 as stack group will make their interface configs obsolete after
a reload.
[confirm yes/no]:yes

Add Units to an Existing S-Series Stack
Units can be added to an existing stack in one of three ways:
• by manually assigning a new un-configured unit a position in an existing stack.
• by adding a configured unit to an existing stack.
• by merging two stacks.
If you are adding units to an existing stack, you can either:
• allow FTOS to automatically assign the new unit a position in the stack, or
• manually determine each units position in the stack by configuring each unit to correspond with the
stack before connecting it.
• If you add a unit that has a stack number that conflicts with the stack, the stack assigns the first
available stack number, as shown in the examples below.
