Working with a T5240/Solaris 10 and trying to figure out if there is a setting that will automatically shutdown the server if it hits a certain temperature. I'm just trying to identify if there is a setting in place and what that temperature is...

Any help is much appreciated!

These information (and settings) should be reachable from the servers ILOM... You can find information about all temperatue (and other) sensors in the servers ILOM guide which can be downloaded here:

Yes, low and high, with leds that light up. Exactly what temp is a mystery -- somewhere beyond 41 - 95 F / 5 -35 C, but you might need a build spec from inside Sun to know what it is. LOM does stand for Lights Out Manager: http://www.fujitsu.com/downloads/SPA...vice-en-04.pdf

Based on the following, is there one particular "sensor" that triggers the shutdown?

MB/T_AMB seems most probable, as overheating fans and supplies, perhaps even cores, can shut off independently and be tolerated. But potentially, all. It might be in the LOM firmware, but might be more direct and incapable of override, to protect Sun from fire liability.

Hard usually means something drastic happens, like power off.

If this server is in a temperature controlled room, all the cooling fans and psu fans are working and the vents aren't clogged with dust there should be no reason why you'd have temperature problems.

If one of the above isn't true, I'd address that before I started to look for a software solution to something that's a hardware problem.
