This document describes how to replace a supervisor module or a stack member of Catalyst 9K switches in HA (High Availability) setup.
None
Cisco recommends that you are familiar with stacking, stackwise-virtual (SVL), and "bundle" Vs "install" boot mode related concepts on Catalyst 9K switches.
The information in this document is based on the following hardware versions. There are no specific software versions needed for this guide:
Note: Consult the appropriate configuration guide for the commands that are used in order to enable these features on other Cisco platforms.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
This document includes the processes to replace a member of stackable switch types:
In this example, you replace a member of a C9300 stack. (The switch is in this example uses switch 2 in "Install" boot mode).
Note: The same process can be used for the replacement of a C9200 stack member.

Note: If the switch is in "Install" boot mode, verify that software auto-upgrade is enabled. If not, then enable that by configuring "software auto-upgrade enable" from global configuration mode.

Note:If the stack is in "Bundle" boot mode, you need a copy of the IOS-XE .bin file that is in use on active on an USB stick or local TFTP server which can be accessed from new switch/member, through it's out-of-band (OOB) management port

Note: If active switch member needs to be replaced, perform a failover to the standby switch in the stack, and wait for it to take over the active role. Skip this step, if you are going to replace any other member of the stack.

Note: The new unit might not be running same software version as existing stack, so you need to match that. For example, existing stack is running 17.3.1 and new unit is running 16.9.3.

In this example, you replace the Active supervisor of a C9404 chassis. (The switch is in this example uses in slot 3 in "Install" boot mode.)
Note: If the switch is in "Install" boot mode, verify that software auto-upgrade is enabled. If not, then enable that by configuring "software auto-upgrade enable" from global configuration mode.

If active supervisor needs to be replaced (like in this example of ours), perform a failover to standby supervisor and wait for it to take over active's role. Skip this step if you are going to replace standby supervisor.
