LinuxQuestions.org - CPU Temperature thresholds.

It looks like it is defined in the file /usr/platform/SUNW,Sun-Fire-480R/lib/psvcobj.conf where the nice line

Code:

/SYSTEM/MOTHERBOARD/CPU_0_2_MOD_SLOT/CPU_0_2_MOD_CARD/CPU0_DIE_TEMPERATURE_SENSOR_class=0,Subclass=1,Instance=0,DIE_TEMP=1,HOTPLUG=1,RDWR=1,LO_WARN_MASK=1,LO_SHUT_MASK=1,HI_WARN_MASK=1,HI_SHUT_MASK=1,OPT_TEMP_MASK=1,HW_LO_MASK=1,HW_HI_MASK=1,VERSION=0,ACTIVE_LOW=1,BIT_NUM=0,INVERT=0,PORT=1,BITSHIFT=0,BYTEMASK=0x0,REG=0,TYPE=4,BUSADDR=0x30,BUSNUM=0,CNTLR=1,Lo-warn=5,Lo-shut=1,Hi-warn=90,Hi-shut=100,Opt-temp=70,Hw-hi-shut=105,Hw-lo-shut=0

appears.

You can also display the threshold values with the command:

# prtpicl -v -c temperature-sensor

Here is an example of its output:
