Hi.
I have a server Proliant DL380 G4, this not responding (there are not video signal) and a amber led marked NM into the system board is light on.

Any idea for resolving the problem.

hi.
I have been replaced the power module but the error persist, could you give me another idea.

Well,surprising the PCM did'nt work.

Clear NVRAM via System Maintenance Switch on the system board.

Last option, replace system board though skeptical if it would make a difference.

Hi Carlos,

I have tried all of these steps my problem still persists, what are the chances of it being the motherboard itself and also how do you use the NVram switch as i have turned it on to clear but nothing happens

Hi, I had this problem and it was because the PCI riser cage was not properly pressed down onto the motherboard. went through same process of new sysboard and power converter module. Had nothing but this left to try, and it seemed to resolve my issue. I reseated PCI cage and pressed down right along the length of the riser cage.

hope that helps

Hi,

the following post also seems to suggest the riser cage as a possible cause of issue:

I had the same amber light on NM & eventually it was down to processot being not properly seated. So, this means either Riser or Processor can cause the same Amber light on NM.
