False CPU Overheat on DL380 G5

We've been fighting 2 servers with the same issue. We've updated the firmware to the latest (BIOS 2008.01.24 (30 Jan 2008))and greatest as well as the PSPs. We've replaced the CPU fans and the fan board. Still no luck ... CPU's show at 255 C. Any ideas?

Re: False CPU Overheat on DL380 G5

hi

first of all
where are you getting those numbers? temperature values?

second of all
any amber - red light?
are servers up and running?


-----------
try this
1. clear NVRAM
2. remove power cable for 1 minute.
3. and also reseat riser cage.

Re: False CPU Overheat on DL380 G5

update to proliant support pack 8.2 and firmware CD 8.2

that's either a system rom issue or HP agents issue reporting incorrect information

Karlo;

Have you tested 8.2 PSP and Firmware for this specific issue?....

I know my servers have 8.1 and I still have the problem.

hi


it's part of the troubleshooting process if you call HP...

since it's false message we have to check if it is a bug in the System ROM or hp agents

Re: False CPU Overheat on DL380 G5

Hello,

It appears this post has been inactive for a time but anyway I´d like to know if there was s resolution on it.

The thing is that I´ve been working with a CU for over 2 weeks now and he has the exact same behavior described at the beginning(255° C on CPU´s sensors). the server is up and running and we´ve applied the latest PSP and FW CD on it with no changes. The IML shows nothing related to temperature and server have not been shutted down due to the same.

Right now I´ve asked the CU to reseat some HW components as well as crearing the NVRAM to see if that makes a difference.

Any suggestions?
Thanks
