RE: Ambient Temperature Shutdown

We had one of our HMC's send us a message about this same thing, saying the
FSP had detected high ambient temperature. We called the customer, who sent
someone into the computer from home (lived only 1 mile away), and they were
able to bring the temperature down by just opening a door and putting a fan
in, the system stayed up.

The guy thought the room temperature was about 85 degrees.

One additional question... does anyone know what ambient temperature level
triggers the message?

Looking for some more advice or past experiences here...

We had an cooling related event sometime over the weekend and things finally
got hot enough for our development box early yesterday morning. It threw
two CPPEA5A messages to QSYSOPR before shutting down suddenly (messages sent
at 6:47 and then 7:04). Behind the scenes, it was logging a
11007203 SRC code, which means that the ambient temp is too high and
shutdown will occur in 15 minutes. The system was down before 15 minutes
elapsed after the second message, though.

In conjunction with the first CPPEA5A and 11007203 messages, the system also
threw a CPF1816 about the utility power failing. Our UPS is in a different
room unaffected by the system room cooling, etc.

We are monitoring and notifying pagers for the utility power
failed/restored/etc. type events, but the ambient temp message is a new
concern. What i'm wondering is, when a CPPEA5A occurs, is the CPF1816
utility power message always sent also? There was really no other
explanation for the CPF1816 unless it was 'triggered' by the CPPEA5A...

The system handled things well coming back up and threw one more warning
11007201 message before issuing the 11007202 that things were back within
normal ambient temp range, but it has been a pretty messy morning.



Is anyone more familiar with the ambient temperature based events? Is
anyone monitoring for such events?
