Hence the requirement to unplug AC before inserting hands, rings. screws or screwdrivers into a electronic device.
All the steps below concerning "AC" are saftey steps rather than functional requirements.
So it should be:
Unplug system AC
open case and set clear cmos jumper.
push power button (nothing should happen)
restore jumper to opertional location
Nothing will happen (no POST) if the cmos jumper is not on the correct Pins, so my first guess is that when you re-installed the jumper, you missed one of the pins.
Does the system status LED flash yellow / green when the AC is applied?
Thank you for the answer.
I did it (2-3 pins covering) correctly.
You asked about LEDs, front panel LEDs or Rear Panel leds?
I have Rear:
System Status Led: Green
ID Led: Solid BLUE
Power Led - OFF, pressing power button don't change anything.
System Status LED - Solid amber. So it's seems it critical non-recovered error. Can it be - my Front Panel Locked? How can I unlock it?
I tried BIOS Recovery too - nothing works...
Also, I had on other server front system status led - solid amber even after 60 seconds. but if cycle AC cord few times - BMC initializes normally and PC booting normally. With solid amber - only fans starting... Motherboard don't boot to the POST.
With best regards, Alexandr.
Yes I disconnected and re+connected connector at the motheboard side. All is OK with pins.
Also no problems on the other side: Front panel side, because I placed other motheboard with the same CPUs and DIMM and all is working correctly.
I think this mobo is dead.
Thank you for help.
I have almost the same problem with other PC.
Led diagnostic is returns: F1 (A&B&C&D leds - ON, E&F&G - OFF; H - ON) error code, but I didn't find in manual what is it.
When I try to do BIOS RECOVERY EFI starts but IFlash32.efi can't flash BIOS. I think can't because I have lines about IFlash32.efi version and nothing more. but EFI didnt' freeze, because I can reboot pc with Ctrl+Alt+Del.
but with ESC key (startup.nsh Cancel) I can run EFI commands.
with normal BIOS Recovery Jumper settings - PC don't start, but Fan is working after power ON. But no POST even I'm waiting many minutes.
Front Panel status Led remain AMBER. Rear ID Led - is OFF.
Rear system status LED - Green & Yellow.
Is this "other PC" also S5520SC? Looks likes BIOS corruption... Did you use the correct BIOS recovery package? You can also modify the startup.nsh file to recover using earlier BIOS version. For more details, see the Recovery1.txt file in the recovery package.
Yes it's S5520Sc too.
I'll try to recover to R0053, for example.
But yesterday was interesting thing: In recovery mode my PC started even OS started to load but with BSOD.
How can it be to see normal behaviour in BIOS Recovery mode?
Also maybe you can help with firmware upgrade, what is better to use full package update with startup.nsh or to upgrade all alone: BMC - restart after, BIOS - restart and so on...? I'm asking because my previous board freeze on DRU upgrade using startup.nsh.
With best regards, Alexandr
I tried to revert to R0050
I have message
" Flashing BIOS..."
IFlash32 BIOS Update Utility Ver 2.6 Build 15

that's ALL it's passed 5 minutes already , no progress, no other messages.
it's seems unable to recover correctly. the same was with R0055, but after shutdown PC with initiating recovery again I saw BIOS ver 55.
It's like process started and interrupted, changed only version.
