[j-nsp] EX4200 show chassis environment discrepancy

[Valentini, Lucio]

Hi folks,
Has any of you ever come across this issue?

If I look at the "show chassis environment output", everything seems to be OK, but when I look at the more common "show system alarms" , it tells me the temp is too high.

Should I worry or can we keep going ? and if so, for how long ? is that perhaps a bug fixed in later versions? I am using ver. 12.3R3.4.

Is it going to shutdown when the temperature raises above 95 deg C ?

Thanks
