RNR-12A (RN4220s) hardware problem
Hi, I have RNR-12A (RN4220s) without power supplies. Unit from decomission. So, I was trying to bring 2nd live to this unit, but I am not sure what is wrong with it. All hardware is present ( exce...
Hello Alein,
The troubleshooting and isolation steps you are doing is beyond the troubleshooting we do and recommend. If we find the device is faulty and it is under it's warranties we recommend to have it replace. We can wait for any recommendations from someone from community that may have encountered the same problem.

I am not familiar with who makes the 4220 motherboard (assuming, like the 4200, it's OEM from another company). You may have more luck going to a forum that supports that motherboard.
In both of your movies, there is no RAM installed. You aren't going to get very far that way.
There are both RAMs :) as in oryginal.
Mother board seems to be Netgear, not OEM from different company.
I was able to find only on this site some information.

I ask them if there is any documentaion to this MOBO, but without respond yet
It seems that 4200 is much better is cause of hardware problem. 4220 is almost impossbile to fix, and I am not sure if there is difference in performance. There is no benchmark of 4220 available.
Currntly I am still looking for any output from this mobo. There must be something.
PS. I am 2nd owner, so I do not apply for warranty as I know since I have no idea, when 1st owner bought it.
Ps2.I have no oryginal power supplies :(
The lighting in your movies was very poor, and I could not see the memory. If memory is installed and you know it is compatible memory installed in the proper slots, and you are sure the power supply is good, then the reaction you are getting at power-up and the lack of any video, even from a BIOS, would tend to indicate that your assumption that the motherboard is good is flawed. The fact that you are not using the original redundant power supply is likely not a factor. It could be as simple as a corrupt BIOS, but you'll have no way to fix that.
There is no indication on the motherboard, chassis, or drive backplane that it might be OEM from another company?
But it does appear you have determined where you can buy a replacement if you want to throw more money at it.
RAM is oryginal, and it is fine (tested)
It is possible that BIOS is corrupted, but it is not hardware problem, as long as it is not damaged internal flash.
There is nothing what can suggest that this is OEM from different company. Only two numbers S-36 and 01017WG0B-388-G.
I do not see any reason to inwest more into this NAS. This MOBO is more expensive that NAS cost me.
In the last resort, I can always use different MOBO with SAS controllers, it shoud fit :) or I will sell chassis to be used in such project.
