The temperature between the two threshold values is the range in which the temperature is
allowed to rise before the fan turns on again.
In addition there is a hardware temperature sensor that will automatically turn the fan ON if the
measured temperature is over 40°C.
Temperature Monitoring
You can monitor the unit's measured temperatures actively by inspecting the temperature
graphs in the Web UI, or passively by setting up automatic alarm messages.
Alarm notifications can be generated via SNMP Traps and Emails, as well as log messages in
the Alarm and Event Logs. The alarms may optionally be masked.
Also, it is possible to implement a delay by setting the number of times the 1/minute readings
need to exceed a temperature threshold before an alarm is triggered.
Monitoring CPU and Board Temperature
Current readings for Oscillator/Board/CPU Temperature are displayed in the System Status
panel, which can be accessed via the HOME screen, or via TOOLS > System Monitor .
CPU and Board Temperature graphs are displayed under TOOLS > System Monitor :
