ML350 G6 - DOWN!!!

ML350 G6 - DOWN!!!

I need som urgent help!
Our proliant ML350G6 was "dead" this morning.
When I insert the power cable, the "System Power LED" is amber. When I press the power button the system tries to start. The system fans starts, but after a few secons they stops again, this happens three times. And then the "Health" led is flashing red.
If you look at the system board, there are 8 LEDs between the power connector and the "DIMM leds" they are marked CR1-CR8, I guess that these are diagnostic LEDs. When the "Health" led on the front starts flashing, the two LED marked CR7 and 8 starts flashing.
These 8 LEDS is not mentioned in the Maintenance and service guide anywhere.

Does anyone know what they mean?

I guess that I need to ordre a new system board, but I would like to be sure.

Re: ML350 G6 - DOWN!!!

Right, it is not in the manuals.
I would check the logs from iLO if possible first, together with the other diag LEDs on the board, e.g. processor, power, fans, etc.

Hope this helps!
Regards
Torsten.

Re: ML350 G6 - DOWN!!!

The only information there is in the IML is that i have sent a power-on signal.
No other LEDs is lit on the system board.

Hi.

If you have changed the motherboard then there must be some component that did not get replaced. Memory, CPU, Raidcontroller Battery or an extra NIC and so on.

Try starting the server with minimal config and go from there. if you are successfull you add a little bit more config at a time and then you'll find out whats making the server not boot properly.

I agree, pull out the pci cards, Dimms, etc. and observe the results.

Hope this helps!

Re: ML350 G6 - DOWN!!!

If present, I would pull the first CPU, insert the second in that slot and try. Same with PSU.

Hope this helps!

Re: ML350 G6 - DOWN!!!

I guess that it must be the CPU, its the only thing that have been reused from the old board.
I have ordred a new cpu.

Hello Jorgen...sorry to drum up this old Thread, but What was the solution to your problem? I'm having the exact same behavior as your issue here, and was curious what was done to fix it for you. Thank you!

Hi,

 

I have this exact same problem. Server just stopped, flashing CR1 and CR2. Relpaced the powersupplies, nothing. Did you get to solve this?

Re: ML350 G6 - DOWN!!!

While checking the system boards LED's booting up, the overheat LED blinked just a single time and immidiatelly put the front LED into status RED. So I let it cool down for 15 minutes. After this the system booted to the OS and I immidiatelly shut down all services so the CPU load would be minimal. This gave me the opportunity to update the system BIOS. After another reboot I checked HP Insight and the log was filled with "overheated zone #2". So I checked the internals and they we're all at normal temperatures. So maybe the BIOS update fixed some temperature measuring problems?

Interesting Atlan....shutting down the server for more than 15 minutes didn't work for me, it's been down for 3 days now, and left off overnight...next morning, same behavior.
I suspect my problem might be the BackPlane as mentioned by the previous poster, just based on what I was doing with the server right before it "went down." :) I was attempting to install a video card that required a power run from the PS. After plugging that in and finding the card didn't recognize in the OS, I shut it down and took it back out; after that, the server now is stuck in this loop. I suspect I may have shorted out the PS Backplane, as both PS's show green LED's on them.
