Hi
In addition to GPs post i would say that extreme temp conditions may result in damaging ur line cards or even the chasis which may start malfunctioning after that..
As a practive measure you can chek up the logs rgularly to know/verify any errors related to the temperature conditions on the site..
u will have logs trigger on the temp conditions of ur chasis..
we had seen enough sup card damages coz of the extreme temp conditions...
