Adding 2 more Catalyst 9300

[ndahemmy]

Hi there,

I would like to add 2 more  Catalyst switch 9300 in the Existing stack below;

The version of two switches to be added is below 

There is fifference in HW version and existing model is 48UN while new is 48U

Can these models form stack ?

Anyone have detailed procedure for similar activity

any recommendation on disabling , disconnecting and reconnecting stackwise cable on existing stack ?

Thank you

EDIT - Looks like both running same version of code.

follow below steps :

1. make sure you offload the config out of the box safe

2. Offline build the new switch  with Correct IOS XE to match with exiting Stack

3. change the Switch numnber and priority.

4. save the config and turn off the device.

5. Prepare the racking and mounting the kit in

6. configure on the Live stack switch provisioning.

7. connect the Stack cable (hope below URL give the information)

8. Power on the new Switch part of stack.

Monitor  the Logs - show switch give you information

Hope this help you

Yes they can stack. Just follow the normal procedure for adding to an existing stack:

Before connecting anything provision the new switches on the existing stack ("switch 4 provision C9300-48U" "Switch 5 provision C9300-48U")

Optional - enable auto software updating on the existing stack to update new switches if necessary ("software auto-upgrade enable"). Also, do you have a 1m stackwise cable? Can't remember if the standard 50cm cable will reach across 5 switches..

Power the two new switches up on their own without connecting to the stack. Change their stack member number ("switch 1 renumber 4" on one switch and "switch 1 renumber 5"  on the other). Power them down.

You can add the new switches to the existing stack without powering it down; my preference is usually to be cautious and shut the stack down. Either way, disconnect the stackwise cable on the existing stack that connects your "bottom" switch to the "top switch". Insert the two new switches into the stack. (By the way, don't forget the power-stacking only supports up to 4 switches, so you'll have to decide on if you're going to wire that as 4 and 1, or 3 and 2).

Power it all back up. Done. Verify that all the stack links are good ("show switch detail", "show switch stack-bandwidth" and so on).
