4. Pack the faulty CP blade in the packaging provided with the new CP blade, and contact the
switch supplier to determine the return procedure.
5. Replace the chassis door.
If you have one or more application blades in the chassis, the Fabric OS automatically detects
mismatches between the active CP firmware and the application blade's firmware and triggers the
auto-leveling process. This auto-leveling process automatically updates the application blade
firmware to match the active CP. At the end of the auto-leveling process, the active CP and the
application blades will run the same version of the firmware.
