Recover from a Card Mismatch State on an S-Series Stack
A card mismatch occurs if the stack has a provision for the lowest available stack number which does not
match the model of a newly added unit. See the following example. 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.
