Replace a failed FP or an FP with at least one failed port to restore or maintain
delivery of configured services.
• “Prerequisites to failed FP replacement” (page 150)
• “Failed FP replacement task flow” (page 150)
Prerequisites to failed FP replacement
• Ensure you have access to 241-5701-600 Passport 7400, 15000, 20000
Configuration Guide so that you can follow the software procedures used
by this task.
• Use a replacement FP with a compatible or equivalent PEC as defined in
“Processor card compatibility” (page 68).
• This task assumes a compatible replacement will be used, that is, one that
maintains the same card services, capacities, and performance
capabilities. When using a compatible FP with increased functionality or
capability, you must configure the slot for the change. When the
replacement FP is a mate card in a sparing configuration, ensure that the
pair can still operate with the lowest existing common functionality,
capacity, and capabilities.
