A ipoGenNoLicenceKeyDongle notification is generated if a system either does not detect presence, or fails to validate a Licence Feature Key Dongle. In the case of an IP500 V2, it indicates that either the System SD card is not present, or that one of the validation checks has failed. Note that removing the System SD card will cause this event immediately, however the licences will remain valid for approximately 2 hours. ipoGTEventStdSeverity will indicate the events state: Severity is cleared(1): license dongle OK Severity is warning(6): license dongle not OK, in grace period Severity is critical(3): license dongle not OK, grace period expired The first check to fail is contained within ipoGTEventNoKeyReason.
