server board How Boot A Singal Node Compuer?

[Visirs]

Hi,linus and other netfriends,

 

  Im a fan of LTT for a long time,now I have joined the LTT forums ,finally!

  May two months ago ,I  got a HNS7200AP Compute Node

  But now,I have many problems on this compute node.

 

FIRST: The motherboard used a power docking board from PSU to catch the power,with a 16pin Molex adapter,input 12V voltage to the motherboard.

 

  This is the PSU controler chip.

 

 

SECOND: After I checked the define of power docking board,I found that it have no any 12V standby input and no any PSU control signal input.However,the fan controler adapter have a PSU-OK signal output!It's really strange!Becaues the PSU-OK signal should output from the PSU itself!Also,the PSU only output the 12V stby,well,ok,but from the define tabel,the motherboard seems only allowed 3.3Vstby and 5Vstby input only.How?Why?

 

So,I guess it must had some other connect from PSU to the board.I found the FrontPanel connecter to the board,Intel called it Bridge Board.Wow,there are many normally adapter like 4xSATA(from SAS),power LED,HDD LED,IPMB,5V AUX,even USB2.0 and more.The most important: the PMBus --- PSU controler.

 

The bridge board's pin define as:

 

 

Here are another photos:

4.The only I have,is a single node like this:

 

 

Now，dear of my friends:

How I boot the computer rightly if I had these problems following?

1.I have no the chassis called H2000G,but the front panel on it.

2.I still can not understand how 12V stby becomes 5Vstby and 3.3V's,by some kind of DC-DC transformer?

3.I can connect the PSU with Power docking board ,it just need some wires,but which other pins must I connected them?

 

Thanks for your reading and reply(hope you can!),no matter it helps me or not!

As wee know,the intel xeon phi 7255 support the virtualization(including vt-x,vt-d),so,a 272 threads processor is fit for this

I just got given a couple of xeon phi cpus and so now I’m looking at getting them setup. Did you ended up booting this node without the main chassis? If so how or do you just have it just collecting dust?
