Hi all!
We have been using this HP ProLiant ML350 G6 for several years (long before I moved into this company) it has always been working just nicely.
But yesterday, I attempted to power it on (nowadays we are used into switching it off since we're migrating from the software that runs on it) but to my suprise, it didn't come up. No any responses from it:
- When I connect the power cable, NO ANY LED light gets on (neither in the rear or front lights)
- Pressing the power button does NOT bring any LED lights on.
- When I plug the power cable to the power supply (at the back) I can hear some "tikting" sound inside it.
- I took the power supply out (you know you can plug it out and insert it back), plugged in the power cable and I hear some "tikting.." sound from inside the power supply. I will hear the same if I leave the power cord plugged in and switched power off and then ON in the power/electricity wall outlet.
- I tried to use other power cords (to figure out whether the current one is damaged) but no success.
- (The server uses KVM switch to connect to a monitor/display unit), so I decided to connect it to the monitor directly, no success --thought I think there was no point in trying this since there is no even a single LED light ON.
- Server has always been running on APC UPS power, I tried connecting it to different other power outlets, no succes.
So this is my problem, I get NO ANY LED light ON.
What could be the problem and how can I solve this please?
Thanks in advance for any inputs,
Frank.

Re: ProLiant ML350 G6 Server doesn't boot, No any LED lights
is this server powered by one power supply only?
In that case there is a fair chance it's just the power supply that is busted.
This would also be the simplest/cheapest to replace and start troubleshooting with.

Re: ProLiant ML350 G6 Server doesn't boot, No any LED lights
Thank you RbBsmn....
I can't see another power supply in my server. (I assume I would see it by an additional power plug in port?), but even after opening the inside, I can't see another power supply. The only one I see is the one you can pull out of the server from the rear/back.
Another problem is I can't find another working power supply of the same to try. Could this be another problem?
Please, how much are they sold?
Thank you!

Re: ProLiant ML350 G6 Server doesn't boot, No any LED lights
The problem could be the power supply backplane, it is under the system board.
Hope this helps!
Regards
Torsten.

Thanks for your input.
What could be the problem with the panel? What can be done?

AFAIR this board converts voltage from 12V from power supply to all others (5V, 3.3V, ...). If the board is dead, no power at all.
Hope this helps!

Torsten.

Thanks again Torsten,
Now I can't be sure whether its the Power Supply or the back plane. Anyway to find out/isolate the problem?
Thanks again.

SolutionHi!
If this happens to somebody, this is how I got an ML350 G6 server to boot.
Server seemed totally dead, no lights anywhere. Only psu fans started to spin when power was plugged in, but psu leds did not light up, no leds on motherboard or front panel either. Tried with one psu, two psu and switching psu slots, no help.
Then I took both PSU:s off and plugged power cord to one psu while it was off from the machine. Then plugged the psu to it's slot, and hey presto, it works! Copying customer's data to safe palce as I write this. Hope this helps.

Hello Ukkonen,
you sir are a genius!
Same exact problem and to my disbelief your solution worked flawlessly. Unfortunately I found your post after the server was already replaced and the backups restored.
Thank you so much for your solution!
All the best
