There was some headache from mushy tiny battery positive terminals. To get the little new battery going, I had to slide in some wires under them and press them down with a tiny piece of electrical tape. I could be useful for somebody else in these situations, so I took pictures with my phone. Wire thickness must be right, and no aluminium foil did not work, in my case at least.

However "poweron"-"poweroff" problem is the same. Still thinks systems is not powered and break command does not work. DVR-ROM Still does not power up or respond to front keypress. I tried the USB ports with a brand new Sandisk memory stick, tested on 2 machines. Both plugging during operation and plugging before power up did not make it show on FRU list with "showfru" command.

Which brings us to motherboard jumper situation. Below are the info available in the manual about Netra240 motherboard jumpers:
Help with Reviving a NETRA240 Pls?-netra240-board-jumpers-01jpg

Code:
JP1[1]
-------------
1-2 Fitted
3-4 Fitted
5-6 Not fitted
7-8 Not fitted
9-10 Fitted
Processor core voltage. Do not alter this jumper setting. Changing the setting for JP1 could cause damage to the server.


JP2
-------------
1-2 Not fitted
ALOM Flash ROM swap halves. Only service personnel should modify this setting. Fitting a jumper affects the swap.


JP3
-------------
1-2 Not fitted
ALOM reset. Used only for testing the system.


JP4
-------------
1-2 Fitted
3-4 Fitted
5-6 Not fitted
7-8 Not fitted
9-10 Not fitted
System configuration. Do not alter this jumper setting.


JP5
-------------
1-2 Not fitted
Only service personnel should modify this setting. Do not change the settings for the JP5 jumper. Only service personnel should modify the settings for this jumper.


JP6
-------------
1-2 Fitted (this is a non-functional setting)
2-3 Not fitted
ROMBO enable. Only service personnel should modify this setting. Fit jumper to 2-3 to enable ROMBO.


JP8
-------------
1-2 Fitted
Clear CMOS. Only service personnel should modify this setting. Fit jumper to 2-3 to clear CMOS.


JP10
-------------
1-2 Not fitted
Override PSON#. Only service personnel should modify this setting.


JP11
-------------
1-2 Not fitted
ROM write-protect. Only service personnel should modify this setting.


JP12
-------------
1-2 Not fitted
ALOM console bypass. Only service personnel should modify this setting.


JP13
-------------
1-2 Fitted (this is a non-functional setting)
2-3 Not fitted
OpenBoot PROM Flash ROM swap halves. Only service personnel should modify this setting. Fit jumper to 2-3 to affect swap.


JP14
-------------
1-2 Not fitted
ALOM AFT mode. Used for testing the system only.

Here is an overall picture of the board with current jumper positions:

I will follow with an ordered picture gallery of jumpers taking care to show jumper number and whether they are set or not.

Soon.

Found this:

Netra T1 AC200 ignoring all serial LOM commands - Servers General Discussion

so it seems like your problem is not unique.

At this point I wouldn't be changing mobo jumpers though.

How About the Power we Supply to Her? :)
That link was great tried a few things they suggested. This may have various reasons, but they all related to some hardware connection it seems. Speaking of that, I was kinda suspicious of the dinky power connection I concocted here. Sun in all its wisdom made a special DC power connector it seems from this manual they have for that esteemed "product" design:

Code:
https://docs.oracle.com/cd/E19256-01/806-2073-10/806-2073-10.pdf

That is exactly what we have here:
Help with Reviving a NETRA240 Pls?-wp_20181103_001jpg


And I do not even have space to make a ground connection.

Help with Reviving a NETRA240 Pls?-netra_001jpg

Following the + / - signs, I just connected +48V to the + terminal, power return to the - terminal, that's it. Could it be that the curiously hunky DC-2-DC power converter we slide in is testing whether we have a legitimate Sun AC-2-DC power supply connected to it? Could this be why its refusing to admit that it in fact has power supplied to it??

That's what? Are you saying it's working?

My apologies Hicks, no its not working, still the same. Since this is a hardware problem, I was simply saying maybe my issue here is the most basic one, my power connection. What I made is a 2-wire connection to a 3-wire socket. I will try correcting that ny replacing the unique plastic connector Sun used with a good quality, market standard metal sleeved 3-wire connector. See if that makes a difference. I am not touching the mobo jumpers per your suggestion.

You could be looking for a poor power connection to the mobo somewhere. I would be reseating all power cables, edge connectors, etc. When you 'poweron' do the CPU fans start? (although I can't remember, I assume that they plug into the mobo). Could, of course, also be a dry joint somewhere.

Earthing question is crossed off.
Correct, Hicks. Thanks. I will do that whenever I have a chance to sit down on it again. Meanwhile I had crossed off the grounding question. Problem is not that.

And I tried both "bootmode diag" command, which does nothing in terms of additonal info, and taking out the cracked front switch bezel and turning the knob shaft with small pliers to Diagnostic position. The flat part of the shaft aligns with the arrow on the cracked blue bezel. I am not sure was really done, as it did not do anything different during SC boot. Maybe the plastic knob shaft is also loose working intermitently. However, it did worked fine and recognized position of the front switch when I turned it leftmost, to "permanent standby" and SC did not even allow me use the "poweron" command. So we can assume the front system switch does indeed function as long as I can put it in required position. Didn't want to jam pliers in any more for fear of breaking that knob shaft too.

Having some diagnostics would sure be useful. Will work more on restoring that too.
