DL360 G2 overheating


I have a DL 360 G2 server that is over heating. The "overtemperature" system board LED comes on and the machine reboots repeatedly. When I remove the server from the rack, I can boot into the OS and the Integrated management log cites that the server was automatically shutdown due to temperature issues. The error reads "System overheating (Zone 3, Location CPU, Temperature 73C). While I know that 73C is off the charts, none of my other 360s in the same rack are having this problem. I have powered the server off to let it cool, but the problem always comes back. I haven't been able to find any documentation on exactly what this led means, other than the obvious.

Does anyone have any idea what exactly the problem is? Do one or both of my CPUs need to be replaced, or maybe my power supply?

Hi Kate,

as it tells you it's an overheating problem, there is something which is not letting your CPUs to cool down. it may be some congestion on the rack, (there should be 1U space between the servers), or may be the fans inside the server are not working with proper speed. check it with management utilities.

Re: DL360 G2 overheating

Not mandatory to have 1U between Servers, I see 100's situation where ¼ inch used between servers, main point nothing should be at the back server to cause air flow circulation, sometimes cable arm pushed to close to server and it cause internal overheating. In your case Kate, I would check: thermal Pad under Heatshink, there is thermal compound sellable around with pads, and it's maybe Heatshink not completely mounted. Is a dual or single CPU? And as kcpant recommend verify SW part System Management HOME Page should show Speed increase before server shutdown, from normal to high

Re: DL360 G2 overheating

Agreed, once you remove the hink sink, try to replace the thermo compound ( non-electricially conductive but thermo-conductive). Also, be sure air flows from the front of the rack through the back, make sure the back of the rack is not pressed against a wall and points to an air return. Use blanking panels to fill up all void space in your rack to allow proper venting. it don't hurt to purchase a rack fan hit. Hope this helps.
