Device High Temperature Incident
Lets see the device high temperature incident and monitor in Prisma SD-WAN. This
incident is helpful to monitor the temperature sensor trends in a device.

The ION 1200-S-5G device has four temperature sensors for CPU, ACPITZ, Cellular
Modem, and PSE. An incident DEVICEHW_TEMPERATURE_SENSOR is raised when one or more
thermal sensors report temperatures beyond the operationally safe threshold value.
This incident is helpful to monitor the temperature sensor trends in a device. If a
high thermal condition persists for a longer time, the device is shut down in the
following cases:
- If the device has a high CPU temperature, an incident is raised. The system will monitor the temperatures every 5 minutes. If the high CPU temperature persists for 3 continuous readings, the system will log an error and trigger a system shutdown.
- If there are any 2 temperature sensors other than the CPU that cross the defined thresholds, the system will be shut down. The system will monitor the temperatures every 5 minutes, if there are any 2 sensors that cross the threshold 3 times in a set of 5 continuous readings, the system will be shut down.
The incident is cleared only if all sensors are within the threshold. It may take up
to 25 minutes (if multiple sensors reported high temperatures before falling within
the threshold) to clear the incident after all sensors are within the threshold
value. If the shutdown was system-initiated, then the following actions must be
taken:
- Initiate a system shutdown in order to prevent any further damage to the device or the surroundings.
- Set the potential reboot reason as Thermal condition shutdown.
- After the system is shut down, you will need to manually bring the device back up.
When operating in high temperatures, it is suggested to monitor the device
temperature activity on the Prisma SD-WAN web interface regularly. If the
high-temperature condition persists for 15-30 mins, the device will be shut down.
You need to bring the device back up manually.
- In Strata Cloud Manager, navigate to .Filter to view your device.View the time series Device Temperature chart.

The ION 1200-S-5G has four sensors, you can see the time-series temperature mapping for each sensor CPU, ACPITZ, Cellular Modem, and PSE. The temperature threshold for the various sensors is:- CPU - 90C.
- ACPITZ - 67C.
- Cellular modem - <-30C or >105C.
- PSE - <-30C or > 115C.
- POE shutdown when CPU temp reaches 85C, no power to the PDs. If CPU temp comes down to 75, power to PDs.
- Reduced performance when temperature between 100C - 118C.
- RF activity is suspended when the temperature is at 118C or -45C.
- Device shutdown when the temperature reaches more than 135C.
- Incident generation threshold when the temperature is <-30C or >105C.
- Incident clear threshold when the temperature is > -25C or <100C.
Monitor the temperature trends around the device. Ensure that the device is away from direct sunlight and keep the temperature under control. Check for any external heat sources. Contact Palo Alto Networks support if the issue persists.
