Good to Know
- End of life. Cisco has announced end of sale and end of life for the Catalyst 3850. Refurbished units are the practical way to spare or extend an existing 3850 stack.
- Stack with 3850s only. StackWise-480 stacks Catalyst 3850s with each other; a 3850 does not stack with a 3650 or a Catalyst 9300.
- Uplink module. Check which network module is fitted, or order one. A slot left empty needs a blank for airflow.

You are adding to, or sparing, a Catalyst 3850 network. You need 48x 10/100/1000 upoe with the IP Base feature set. Your uplink plan uses a module from the supported list above.
