Solaris Error Log

I need help from expert to explain to me what are this log about:

Oct 1 07:50:27 LOCALHOST rmclomv: [ID 111618 kern.crit] SC initiating soft host system shutdown due to fault at FIOB.T_AMB.
Oct 1 07:50:28 LOCALHOST rmclomv: [ID 222544 kern.error] SC Request to Power Off Host.
Oct 1 07:50:28 LOCALHOST rmclomv: [ID 751331 kern.crit] TEMP_SENSOR @ FIOB.T_AMB has exceeded high soft shutdown threshold.

Some of google said the log means the SunFire is reach high tempreature and being shutdown by system itself. Is it true?

Yes, the machine will protect itself by shutting down to avoid overheating.

Check that
-all fans are running
-air flow is not restricted or blocked
-the ambient temperature is within the range specified by Sun. Check the hardware manual for this (optimal temp is usually 69F-73F (20C-22C))

It looks a over heated system. Please see the link  below for a script (you have to request for it) that monitors temp.

Seems this particular request is done by the remote management card (SC).

I'm not sure you can modify the parameters but you really don't want to change the temperature shutdown settings. You could really destroy the hardware if you let the server run too hot.
