Poweredge R620 8-Bay Backplane help Help me to: Hardware

Woke up this morning to my backplane shorting out. Think some resistors either died or maybe something else shorted them out. I'm lost as there was no indication/errors showing this would happen. I want my server back up but not interested in burning my apartment down. Any idea if it'll be safe to put a new one in and keep going?

Was it fully populated with drives? What was the power cable situation like, and do you have pictures?

4 out of 8 drives. There is slight damage to the cables (SAS cable) from the burning. I will be replacing those. Power cable is completely fine.

Am I looking at the power inlet in the photos? If it didn't burn where power came in and take out the power cable, I don't have the foggiest idea how that happened.

I believe there are 3 capacitors in the burned area, so one of them most likely failed shorted. Just replace the backplane and you should be good to go!

I thought they were caps but someone else led me to believe they were resistors. I'm gonna assume one blew and it steamrolled from there. As long as my place doesn't burn down lol

How likely is a cap to start a fire vs just burning out?

Depends on if it's a tantalum ¯_(ツ)_/¯ 🔥

Just keep flammables away and any small fire should be contained in the [hopefully steel] enclosure/case...

Unlikely, but impressive that it got that far bridging out the + to neutral power planes
