How to implement the third extreme switch on the stack?


Hello to all,

This is my first post here at the community, and to be sincere, I am not very comfortable with extreme. However, here is my situation:

I've got 3 switch on stack, but 1 one them has just broken and I did the RMA and now I have a new one.
I already did the upgrade of firmware and applied the license. I want to know how can I ad this new one to the stack ?

Could you guys help me on it? if possible a step by step 🙂

Hello Ed,

Welcome to the HUB!

If you are attempting to replace a node that was already present then you can simply use the directions below:

If you are attempting to add a node to an already existing stack where the slot hasnt been configured already then you can use the directions below:

https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-add-a-node-to-a-stack

It looks like you have done a lot of the grunt work on the new node. Just make sure the partition matches the stack (primary or secondary) and as long as the current master sees the new node all the commands can be placed into the master.

Please let us know if you have any questions. Stacking can get a bit tricky if you are not used to it.
What switches do you have?

When replaceing 460s and 440s we use the following procedure.

On the new switch:
Make sure you are running on the same partition of the stack
Make sure you are running the same code as the stack


You can now connect the stack cables and while the new switch is rebooting.

Connect to the master and wait for the new switch to come online.
sh stacking
verify that the mac-address on the new switch matches what shows up next to disabled node on the current stack.

Copy the mac-address of the new switch.
Run these commands below from master switch:

sync stacking node-address "mac-address"
y

configure stacking node-address "mac-address" slot "x"
enable stacking node-address "mac-address"
reboot node-address "mac-address"
y

# Replacement switch will reboot and come online.
show slot
show stacking

You should be all set the new switch ports will be configured the way they were on the old slot

Good stuff Ed....great to have you join us.

Thanks for your trust in Extreme.
every switch in a stack has a slot number for itself.
use the "show slot" command on the master switch and you'll see all the stacked switches and their slots.
Slot-1 X450a-48t X450a-48t Operational 50 Slot-2 X450a-48t Operational 50

then if you wish you go to any stacked switch just use telnet
telnet slot 2
