I think I figured it out.
Probably voids the warranty however :-(
Solution was to replace the 3V CR2032 battery on the cpu board. I don't know if resetting the BIOS or installing a fresh battery was the fix. The original battery had a voltage of 3.07 using my multimeter. I had a new battery on hand, and the fresh one had a V of 3.27. The experiment to do would be to put the original 3.07V batt back in and see what happens.
Had to remove the circuit boards from inside the case since I could not get to the battery otherwise. I removed the sides of the case. There are three boards and the fan assembly. The fan is plugged into what appears to be a system board. The system board has a heat sink over the quad core ARM cpu, and the mount holding the 3V battery. The two SATA data/power connectors are mounted on a small board plugged into a connector on the system board, parallel to the fan assembly. The third board has the DC in, 2x network jacks, 2x USB3, and single eSATA ports, also plugged into the system board, parallel to the fan assembly. I removed the fan assembly, then the SATA board, then the DC power/external connect board, then the system board. I popped out the battery then replaced it. Assembly was in reverse order: system board --> connector board --> SATA deck --> fan assembly. I put the sides back on. Connected the AC adapter then pressed the power button. After the LEDs stopped blinking, both LEDs for for 1 and 2 were lit and steady. I power cycled to confirm all was repeatable. I was unable to log into the admin page, so I did boot menu to the reset to factory default.

I noticed that there are no supported 10TB 5400 rpm drives on the HCL of any vendor.
That shouldn't matter, there are plenty of other sizes that do have 5400 rpm.
I agree the drive ought to work. Please do follow up when you get it sorted.

Wow, I sure hope that it wasn't just the battery that was the issue. If it is, Netgear is going to have a lot of irate customers when batteries on those models start to fail in the future. Your disassembly and reassembly may have fixed a poor connection, too.
I have only seen the battery fail on much older systems. There, the only thing it appeared to affect is that the time was wrong on boot until the synchronization with the time server completed.
Thanks.
That is why I think it was maybe a matter of simply clearing the equivalent of BIOS. The voltage for the installed battery in my RN212 was not optimal though.
Again, the experiment to do would be to put the original battery back in then see what happens.
I have also posted to my support case. If the Netgear phone support lady contacts me, I will inform her also.
Yes, a low batt in a brand new unit has to be rare, but I have seen it happen with PC system boards. One instance I remember was when the vendor my employer was using notified us to change all the CMOS batteries for a certain model of desktops, in the range of serial numbers we had deployed. When the tech opened my PC up, the battery was actually smoking OMG. The source was a bad lot of batteries from the OEM manufacturer. Failures were noticed after the batts left the factory, then traced back by lot numbers.
On a side note, here is the link to a post from another user who had a similar issue, but he solved it in a different manner--
Hey, I found this thread:
Includes a way to reset/clear BIOS and CMOS without any disassembly:

Hi geishaslave , congretulations to solve this tough one. The second reason you now can be happy of is you got the disks for an un<freaking>believable low price.
Kind regards
