EMERGENCY monitor.globalStatus.critical: Chassis temperature is too low.

Chassis temperature is too cool: NVMe1 Temp is critical low (-91 C).

ALERT monitor.chassisTemperature.cool: Chassis temperature is too cool: RiserL LTemp1 is critical low (-48 C).

Chassis temperature is too warm: CPU0 Temp is critical high (39 C).

Chassis power supply 1 is degraded: PSU1 InVoltage is Critical Low (72000 mV)
