I have an DL380P Gen8, the server was sit on data center rack turned off for about 1 year or more, its the same configuration from the factory, nothing changed.
Then when trying to power on, only the power led remain orange, no blinking but no power on, nothing on Diagnostic Panel, i tried several times and nothing, the UUID button not working too, nothing!
I inspected the board, striped most components, cleaned PSU contacts etc, still nothing.
On the main board there's a LEDs called Port 84 from 7 to 0, after some time the 7 lit and after some seconds start to blink.
And there's 3 other LEDs on the board, but 2 lit:
Trying to access iLo or ping the IP was not working, but theirs a LED on iLO port, after some network check i found iLo getting some IP from DHCP, i tried access with all know password, but unsuccessfully. Then cleared NVRAM and set iLO insecure, but turning on 1 and 6 on DIP Switches block, and still nothing, always says wrong password, even the default on from the label, and there's something odd on iLO name, its now iLO-------x in the name, where x is random, but is supposed to be iL0+serial or something, when SSH ask user and password but all incorrect too.
So, i cant power on the server and cant access iLO to check what is going on, and have no idea what the Port 84 LEDs means, anyone have an idea?
Hi
Thank you for writing to HPE Community.
Please check the PSU LED, if its off/green, PSU is most likely good.
If you have already reseated all Procs and DIMMs, then try using Min config and check.
If the server behaves the same way then you may need a replacement system board.
THank you

Hi everyone,
Hope everything is ok with all. First i would like to say sorry for my english, i'm from Portugal and i'm having the same issue.
Dis any one seem to find a solution?
My server has beeing working for over 8 months, but last saturday i had to make some changes to my electric plugs so a shutdown the server and did what i had to do.
Since then the server dosent turn on, well it does but shuts down emidietly as soon as the lights of the disks and disks start to spin.
I get the same lights on as mencioned above but also a red one over the network light blinking next to the power button.
I can enter Ilo witch gives me the indication of system health critical but when i press there ot goes to system information where there is a red symbol on BIOS/Hardware Health as Failed.
What could it be?
I leave some photos.
One more thing, i have removed every componente i have on the server e tried putting one by one but it does the same and also tried to use the swap ROM but since it dosent boot, it dosent change the backup ROM.
(ram, cpu, sata controler, disks, nic's, psu, etc..)
I also checked the PSU LED and it is off, i only see it green when i turn the server on but shuts down emidiatly as i mencioned. 
Hope some one can give a solution what it is.
Thank you.
Hello hunter86,
Yes my light is Fast-flashing red (4 Hz/cycles per sec) = Power fault**.
On my ILO logs i don´t seem to find any erros what so ever except the ones i sent on the pictures.
I did downloaded the Active Health System Log but dont know how to open it.

Here is also my IML log and ILO Event log. Don´t know if it helps.
Any way do you think is better to open a new thread?
Thank you.
