Description: The current state of internal hot failover detection for both Bus A and Bus B. Setting this variable to enabled(1) invokes internal hot failover detection/monitoring and enables the chassis to the primary hot failover configuration. To modify the internal polling frequency or the internal retry limit, you must first set this variable to disabled(2), make the modification (with the Internal Polling Frequency or Maximum Polling Retries variable), and then set this variable to enabled(1). Under certain conditions, enabling can fail; when this happens, a General Error status is returned. (Refer to the ASN file, Racal-INXNMM for detailed error definitions)
