Actually customer has P9500 also, which powered off for now. But will be used in future. And, as i now, IRS7 doesn't support it yet.
So, any event should be displayed by SEA? But i have checked it when replaced parts from enclosure, and there were no events. But, when i was generated test event from OA, there was "genericTrap", and it was "Delivered:ISEE".
