Many external conditions can raise the CPU/memory board temperature and compound high temperature problems, including:
Room air-conditioning set incorrectly
Lateral cooling obstructed
Some Solaris software environment issues can also affect the CPU temperature, such as bound threads or having only one CPU/memory board in the system. These Solaris software environment issues can cause a fallback to the existing shutdown behavior.
The CPU over-temperature safeguard does not affect the Solaris software environment in any way. COS operates only when the temperature of a CPU/memory board exceeds the safe operating range.
