[CAUSE] The tmnxSysSwFabFailRecDetected notification is generated when a condition has been detected within the router that might be resolved by the running of the automatic switch fabric recovery process. [EFFECT] If the automatic switch fabric recovery process is enabled and all the required prerequisites are met, then the recovery process will start. If the automatic process is enabled but the recovery does not start, then the prerequisite conditions should be checked to determine what needs to be corrected to allow the process to run. [RECOVERY] If the automatic switch fabric recovery process is disabled, then contact Nokia support to determine if it should be enabled for this router. Otherwise, no recovery is necessary.
