I called HP tech support. They suggested I replace the Power Supply back plane as there was a known issue with it. I ordered a replacement and installed it today. Even with this replacement, it does the same exact thing.
Thank you for any assistance.
Solved! Go to Solution.

SolutionOut of curiosity can you please try the following (if you have 6 fans installed): -
Remove all redundant fans and restart.
(See the attached image). Leave fans 1,3 and 5 installed and remove fans 2,4 and 6 to see if this makes any difference.
If it does make a difference you may have been issued with an older revision PSU backplane.
I hope this helps.

Re: ML370 G3 shuts off and then powers back on
Does anybody know the correct revision of the PSU I should obtain? I can get numbers off this board I ordered, but I will have to get it back out of the ML370 (not a big deal).
I am going to test the removal of the fans later today.

Re: ML370 G3 shuts off and then powers back on
I unplugged the server and removed Fans 2,4 and 6.
I powered up the server. The POST and SCSI startups all proceed without error.
However, the Attempting to Boot from C: comes up. The system does the two beeps, and the screen goes black.
I don't think the Operating system is even starting. When I press the power button, the system immediately shuts off. When Windows Server 2003 is actually starting up or running, the press for 5 seconds is what it usually takes to power down the server.
At this point, I am wondering if the entire system board is not malfunctioning or has some serious problems.
I am going to look for diags to run on this server. If anybody has any suggestions as to what else to try, I would appreciate it.

Re: ML370 G3 shuts off and then powers back on
When the system would not come back online after removing 2, 4 and 6 fans, I started over with the SmartStart 7.70 CD without the 2, 4 and 6 fans in the slots.
Once Windows 2003 was reinstalled and operating, I powered down the server. I put that fans back in (not sure if I got them in my original slots or not). However, the server is up and running right now. I have had it on for about an hour with no shutting down.
Even if it doesn't shut down, I am not sure I entirely trust it either. It is supposed to become an Exchange 2003 server for a bunch of attorneys. And they tend to get a bit upset when their e-mail goes offline......
Thus my dilemma..... Thank you for all the suggestions I am getting!

Re: ML370 G3 shuts off and then powers back on
Prior to the backplane arrival, I had ordered two new power management modules for the processors. They did not make any difference. However, I offer this for anybody else with a ML370 G3 having this same problem. It was suggested to me by HP Tech Support.
