Temperature / fans X440-G2

[tcheurby]

Hello,
I'm trying to deploy an X440-G2 switch but I meet a problem with the equipment

When I plug in an AP 7522 for example, after 5min I have the fans racing and making a monster noise, with a temperature rising up (I only have two ports plugged in on the switch) another POE equipment causes the same thing... This is the first time I have deployed an X440 switch, has anyone ever meet this problem?
Switch faulty?
I am in version 22.7.1.2, I was able to find on the Hub similar topics but that indicated that they were fixed with a version 22.7.1.2.

Thank for your help

This is within the "normal" range.
Normal operating temperature range for Summit G2 switches or Summit switches running EXOS 21.x or hi...

Indeed I don't really understand why it displays such a high temperature.

We are very few connected users (max 5 users), the switch must operate at least 5% of its capacity.

Fans are OK and PoE is only 7.2 W, but I think the temperature seems very high. It is probably a temperature taken close to the CPU, but since the m´normal range is 10-100, 90 is very high. Is your CPU utilization high? That may be an entirely different problem, but worth looking into.

Hi Fredrik ;

The first measurement was taken at the same location. The switch is in a room where it is either about 23°.
I actually think that the temperature should be the same as the CPU temperature because the switch is not very hot.

Here is a report from this morning still in the same room with POE consumption.
