Summary

Hardware that supports monitoring will display different information about hardware status, like temperature, voltage, current, fan-speed, etc.

Example on CCR1072-1G-8S+ device:

          cpu-overtemp-check: yes
      cpu-overtemp-threshold: 100C
  cpu-overtemp-startup-delay: 1m
             cpu-temperature: 46C
           power-consumption: 62.9W
          board-temperature1: 31C
          board-temperature2: 34C
                psu1-voltage: 12.1V
                psu2-voltage: 0V
                psu1-current: 5.2A
                psu2-current: 0A
                  fan1-speed: 6375RPM
                  fan2-speed: 6436RPM
                  fan3-speed: 6375RPM
                  fan4-speed: 6467RPM

Voltage

Routers that support voltage monitoring will display supplied voltage value. In CLI/Winbox it will display volts. In scripts/API/SNMP this will be dV or value showed in CLI/Winbox multiplied by 10

Icon-note.png

Note: Routers that have PEXT and PoE power input are calibrated using PEXT, as a result, value showed over PoE can be lower than input voltage due to additional ethernet protection chains.


Icon-note.png

Note: If old revision CRS112, CRS210 and CRS109 devices are powered with PoE - Health will show correct voltage only up to 26.7V. If higher voltage will be used - Health will show constant 16V.


Temperature

Routers that support temperature monitoring will display temperature reading. In CLI/Winbox it will display degrees Celsius. Using scripts/API/SNMP this value will be shown in CLI/Winbox multiplied by 10. There are various temperature sensors depending on the device. These sensors may refer to: cpu-temperature, pcb-temperature, sfp-temperature.


Fan control and behaviour

/system health set

Using this menu users will be able to control fan behaviour on TILE architecture devices. Currently, for other RouterBOARD devices, there is no option to manually control FAN behaviour.


Icon-note.png

Note: Improved FAN stability starting from version 6.45.5.


There are three parameters that may affect fan behaviour: PoE-out consumption, SFP temperature and CPU temperature. As soon as one of the parameters exceeds the optimal value - fans are started.

PoE-out consumption

If device has PoE-out, then fan RPM will change as described below:

PoE-out load RPM % of max FAN speed (DC fans)
0%..24% FAN speed 0%
25%..46% FAN speed 25%
47%..70% FAN speed 50%
71%..92% FAN speed 75%
93%.. FAN speed 100%

For devices with PWM fans speed will rise/drop smoother and will change linearly from 9..88% (below 100W min RPM=0)

CPU and SFP temperature

If CPU/SFP temperature raises higher than 58C, fans will start spin. The higher is temperature, the faster fans will spin. For devices with PWM fans spinning will be smoother and if normal temperature will go higher then 58C, CPU/SFP will try to keep its temperature at 58C if possible. The same condition goes for DC fans, but here min fan RPM is higher, which may result as CPU/SFP are cooled till temperature when fans turn-off completely. As a result, temperature can slowly go back to 58C and fans will turn-on again.

Currently exception is S+RJ10 modules. Fans will start to spin if these modules will reach 65C or higher temperature.
