You may have an oem board in this case? you may need something to direct program like a CH341A

bought a new backplane from eBay, replaced and everything works now! Must be some part of the power control circuitry damaged somehow.

LOL, I'd have to refuse the replacement then! I'd consider this is the early Christmas gift then.

Just power it on, it also comes with 2x4210R, 408i controller and sas expander. I wonder if shall just happily accept without asking more and leave 5 star review?

Package arrived, I received DL380 Gen10 SSF without any drives!!! what shall I do???

Just tested on 847, funny enough this time 5V light up and 12V missing. I think definitely something wrong with the backplane power circuitry! Time to spend some money!

I think you probably right. I opened up one PSU and also see no visual damage. And how the motherboard still power on normally if missing 5V power. IPMI shows no error except the SAS controller complaining no drives. Just checked a used backplane is about $60. I might just get one once I...

Yes, the backplane is powered by 3 Molex via a special supermicro cable connect to the motherboard. I believe it's due to the backplane is also used in CSE-826 which does use a lot of molex for power. I do have a 847 currently running which is my main server. Just a bit hesitated to try it on...

I never know that. Let me try the backplane on another chassis with standard Molex.

Used multimeter tested power output from the motherboard without backplane connected. Can see 12V output but no 5V..... I need test more.....

U series direct attach to power supply. But both power supply failed at the same time is still suspicious.... X11DPU | Motherboards | Products | Supermicro

Just put my old x10DRU back on and still no 5V, started wondering it's power supply....

Just measured the board, the x11DPU mother board missing 5V output!!!! This is going to be expensive..... Edit: Just put my old x10DRU back on and still no 5V, started wondering it's power supply....

That's great info! This is my backup server and most of the time it's off. I'll check! Thanks again!

Thanks! I did take it off yesterday and with my old eyes I could not see any visual burn. I also replaced the SAS controller yesterday evening to see if it's due to the controller and seems the same. So far seems the backplane is dead. I'll measure input voltage later today and see if the power...

Hello, My 829U server suddenly stopped working today due to not able to detect any drives. No drives has any LED and the J29 heartbeat LED on the backplane (SAS3-826EL) remains on. According to the manual the normal state of the LED shall be blinking and steady on or off state means something...

Yeah, I guess so. I'm currently running 3 LFF servers and I always want a SFF. I have a DL380 G9 with 2x2690V4 and running my database services. I'm thinking of selling the 380 and moving the services to this SFF. It may improve the database performance in the future. Someone took the other 3...

That's an issue to be solved in the future :D

For myself I'm not flipping hardware. I'm trying to get a sff server with many ssds. I guess in this case I may be able to have a free chassis (by gutting out the drives). And I might sell my DL380 G9 LFF later.
