Fortigate 60D overheat ?

Hello all,


I've some troubles with a Fortigate 60D-POE.

The firewall stops working, and 2 LEDs are flashing green (the 3 little lines LED on the left, as well as the PWR led). All other leds are off.


I notice it happens during the hot days we currently have in Europe (indoor temperature is 28-31 degrees).

I didn't find any information in the documentation, but it looks like an over heating issue.

It seems there is no temperature sensor in the box, so I don't have monitoring information.


If I unplug the firewall from the power, and wait a few hours, it starts working again.

On the datasheet, the operating temperature is 0 to 40° celsius, so I am in the range.


I'm running OS 6.0

I wonder if the issue is expected, or if there is a hardware issue with either the box or the power supply.

Thanks in advance,
