Chassis Hardware Monitor (Events) INLET_OVERTEMP

[Matthew Ghofrani]

Via EMS, my Rp8400 was reporting "The system intake temperature is too high" but it did not tell me what the temperature was at the time the email got generated. I have checked this EVENT #33 on HP's web-site with no luck. I am sure this EMS script knows or is set to go off at some pre-defined temperature. Does anyone know what that is or where I can find out more short of placing a hardware call to HP?

Thanks in advance
PS. I had some AC issues which since has been fixed.

Matthew,

The triggers for these alarms are in the kernel or hardware, not in the
monitor; the monitor is informed that the temperature has reached the
Critical or Emergency level, it is does not determine the levels itself
by checking the temperature level. You'd need to ask someone in the
hardware team to get the threshold temperature for that specific server.

Regards,

Jaime.

Thanks a lot. I will do that

Not sure if this works for your model (taken from a similar one):

MP:CM> de

Display status of the selected MP entity (for use by trained personnel only)

B - BPS (Bulk Power Supplies)
U - CLU (Cabinet Utilities: Fans, Intrusion, Clock's etc.)
A - PACI (Partition Console Interface)
G - MP (Management Processor)
P - PM (Power Management)
H - Cell Board Controller (PDHC)
Select device: u

Enter cabinet number (0 or 8): 0

...

Inlet Air Temperature : 26 deg C
Altimeter Status : OK
Operating Altitude : 5000 - 7000 ft (1524m - 2134m)

What value did you get?

[Matthew Ghofrani]

I got 25 now but don't know what the temp was at the time of no AC.

PS. Do you know at what temp they are designed to shutdown due to over heating?

[Torsten.]

Not exactly, need to lookup the specs...

I guess somewhere around 36 to 40 celsius.

[Matthew Ghofrani]

I opened a case with HP because my managers need exact numbers.
1- At what temp the EMS kicked off?
2- At what temp the rp8400 is programmed to shut itself down?

To be honest, I am interested to know too.

[Torsten.]

These are the stages:

- overtemp warning
- critical warning
- OS shutdown
- power off

There are only some degrees between, but the numbers are different for different models.

Please come back with your findings.
