Recover from a Card Problem State on a Stack
If a unit added to a stack has a dierent Dell Networking OS version, the unit does not come online and Dell Networking OS cites a card
problem error.
To recover, disconnect the new unit from the stack, change the Dell Networking OS version to match the stack, and then reconnect it to
the stack.
