If a unit added to a stack has a different Dell EMC Networking OS version, the unit does not come online and Dell EMC Networking OS cites a card problem error.
To recover, disconnect the new unit from the stack, change the Dell EMC Networking OS version to match the stack, and then reconnect it to the stack.
