P2 Therm Margin shows Warning

Hello everyone,

we received from our Netbackup Appliance 5230 a warning regarding the temperature from P2 Therm Margin (Hardware Error/Warning(s) Notice).

Temperature: 0 degrees C

LowWaterMark: -128 degrees C

HighWaterMark: -15 degrees C

State: Warning

How do I have to interpret these values? Can this be a bug or something?

Thanks in advance!

Best regards
