Hi There,

I have a HP Proliant DL320 G5 it was given to me in a faulty state which I am trying to rectify.
It powers on however there is nothing on the display no hdd activity, and the front panel is flashing red.
I opened it up and powered on to see what activity was taking place and there is a CPU fault light which is amber and a PPM light which is also amber.

I have replaced the CPU and powered on the system the lights remain amber with no display.

Any advice would be appreciated.

Many thanks

I would you would have to replace the PPM raher than the CPU. I think it's soldered onto the motherboard though. Is there a small board in a clip with a heatsink on it near the CPU?

(Rectify is near enough what it does, it creates precise voltages for the CPU so it's a mini-PSU and PSUs have rectifiers in them ;)

Thank you for your input. I shall check on the board and will update the post.
I have also swapped the board from a known good machine with the same lights displayed however it does not seem to provide power to the four on board fans.

Many thanks
