DL380G5 Interlock fail, No power

Hello,

Today i experienced some strange behaviour on one of our DL380G5: After removing it from the rack and install it to another one the internal status LED began to flash red. The LED indicating an interlock failure lit up.
After searching through the forum i thought the issue was that the pci riser was not seated correctly. Removing and installing it a few times does not show any improvement. Another thread suggested it might be a faulty power supply. Therefore i switched one from a running machine into the faulty one: problem still exists. I removed the psu bay completely, cleaned it and inserted it again: problem still exists.
After that i completely removed every part and put it back together just to see the status LED still flashing red.
On the mainboard there are a few LEDs labeled CR4, CR5 ...
As soon as i plug in power the first 4 led begin to light up one after another. a few seconds later CR10 and CR11 are both flashing. The other LEDs go out after a while.
I also swapped out the battery on the mainboard.
Also tried to remove all batteries/psu and switch the dip 6 (maintenance) to on and power the server up. Nothing happens.

Before buying any replacement parts i would like to know if this is a known issue or can be resolved in another way.

Sincerel,

Daniel Laube

By PCI riser you mean the entire cage, correct? Try reseating the cage again and while doing that observe that it is firmly and evenly seated before and after you tighten the screws.  Check the service guide

Yes i mean the entire PCI riser cage. Reseated the cage a fourth time now. All contacts go straight down the slot and all the way in. I even checked the slot for dust.
But the led's still flash and no power on.
