HP Proliant ML150 G5 Turns itself off after power-on

HP Proliant ML150 G5 Turns itself off after power-on

The unit will turn off after 15-20seconds after power on. Initial POST screen flashes up on VGA output a split second before powering down. CPU and RAM are detected.

Logging into the serial console and running a few commands, the last log record shows this:

Properties
number=37
date=07/10/2008
time=13:33:04
sensordescription=Inlet Amb Tem
eventdescription=Lower Critical-going low
eventdirection=Assertion

Would this be the reason the unit is turning off?

Reading the sensor directly:

show oemhp_sensor_num39lun0
oemhp_sensor_num39lun
Targets

Properties
oemhp_readingtype=1
oemhp_sensortype=1
oemhp_status=61
oemhp_reading=128-
oemhp_sensorstring=Inlet Amb Tem


What values should be read here?

If this is a faulty sensor, how can I find out where this temperature sensor is?

Is the PEF configuration enabling the unit to turn itself off on this sensor event? If so, is there a way to turn off the PEF via command line? (I do not have iLO 100c card, serial console is my only way of configuring the device)

Would appreciate any help.

I've seen similar issue and it is the temperature sensor cable I don't have the spare part number handy

just call HP and request this part to be replace it is just a simple cable

just open your box I think you can get it
it is one of the cables that goes from the bezel to the System Board

Thanks for the reply, I searched the HP Parts Store and found: 460423-001 - Temperature sensor cable - For 5U rackmount chassis.

I have started to track down HP resellers in Australia that will have this part but it looks like I'll have to order it from the US so it might take a while.

In the meantime is there any way I can bypass this sensor (either in hardware or via the serial console?)

Cheers.

I found that issue for DL180 G5 which shares the system board with ML150 G5 so both have the same issue but different parts needs to be replaced

I think you can try remove this temperature sensor cable from system board and server will boot up fine well at least that worked for a DL180 g5 I hopes it does the same with the ml150 g5

but does not your server have warranty? a G5?

Even with the temperature sensor cable removed, the problem still occurs.

I did not buy the unit direct from HP, I will follow up regarding warranty.

Has anyone found a solution to this? We have a ML310 that sounds like it's doing the same thing. HP's support has been working on the system over four days now and still have no clue!

Thanks!
