Recover from a Card Problem State on a Stack If a unit added to a stack has a different 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.

To recover, disconnect the new unit. Then, either: • remove the provision from the stack, then reconnect the standalone unit, or • renumber the standalone unit with another available stack number on the stack. Stacking 885
