FanSpeed is 0 in SNMP Traps

Hello,

we are detecting that fanspeed is cero when we attack the OID:

snmpwalk -c sd7364 localhost 1.3.6.1.4.1.3375.2.1.3.2.1.2.1.3

F5-BIGIP-SYSTEM-MIB::sysChassisFanSpeed.1 = Gauge32: 0

F5-BIGIP-SYSTEM-MIB::sysChassisFanSpeed.2 = Gauge32: 0

F5-BIGIP-SYSTEM-MIB::sysChassisFanSpeed.3 = Gauge32: 0

F5-BIGIP-SYSTEM-MIB::sysChassisFanSpeed.4 = Gauge32: 0

Do anyone why that is happening?

I saw the same values in al the other F5 in our sites between different models and version

Regards,

Aitor
