Figure 50-21. Recovering from a Stack Link Flapping Error
Recover from a Card Problem State on an S-Series Stack
If a unit added to a stack has a different FTOS version, the unit does not come online, and FTOS cites a
card problem error, as shown in
Figure 50-22 . To recover, disconnect the new unit from the stack, change
the FTOS version to match the stack, and then reconnect it to the stack.
Figure 50-22. Recovering from a Card Problem Error on an S-Series Stack
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 (
Figure 50-23 ). 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.
