I wish to know what are the factors that can lead to this kind of event. It happened twice to one of my routers and it brings the power of the router down and was resolved by replacing the fan tray module. So naturally I thought it comes from the fan tray. However, when I install the faulty fan tray into the standby router of the same model, supervisor and linecard installed, the problem did not occur. Its been three months now since the problem occur. I still have no conclusion for the root cause.
Can somebody please explain the logic behind the action the supervisor card will take when it encountered this event (major). I am using supervisor card 6-E. To me it seems that is does not consider the temperature of the chassis, otherwise I would find system messages related to termperature. In both cases, there were no such messages.
