Re: ML370 hot swap fan problem

This is likely a system board problem. This is an issue in this machine which will cause this. This issue is actually resolved by having the latest firmware installed on the server, but once you start getting the error it's too late.

I would contact HP support for a replacement system board.

Hi Chad,

If you are not able to boot the server because of the fans (which usually is the case--as server stops right away the temprature rises when the fans failed to work)the only option you have is to replace the systemboard. However, if you are able to boot server to a certain extent that allows you to flash the BIOS you can try that.

Look the spare part# on the systemboard to order or if you post the processor speed and the generation of the server we can help you to find out the part#

Re: ML370 hot swap fan problem

The firmware which would have prevented this is dated 08/05/2004. The only HP will support for this server, though, is the latest:

I did the updates to no prevail. I guess the only thing now is get a new board.

Re: ML370 hot swap fan problem

Updating the fw on a server which is already exhibiting this problem will not resolve it. I would definitely recommend updating the fw on any other ML370 G3s you have before the same problem happens on those.
