Dear fellow Juniper-users,
I recently replaced a SRX240HE2 with a SRX340, using the same configuration in the same environment.
All works fine, I have no alarms, but I do see a rather high CPU temperature of over 70C.
The SRX240HE2 used to have CPU temps of around 44C, as you can see the temp of the routing engines is the same.
I can't find a temperature threshold for the CPU itself (only for the RE).
The CPU load is very low (Today it hasn't been over 10,4%) and the fan speed is normal.
Is this normal behaviour for a SRX340, having CPU temperatures far above that of a SRX240, or could it be a hardware/manufacturing problem?
