Hello Intel,
I used i210 device off function, and look datasheet 6.2.19 bit15 setting to 1b.
So I change value B200 at address 0x1E.
And circuit used jumper JP_LAN2 setting pin.28
Then have two setting
1. 1-2 : Enable Lan i210
2. 2-3 : Disable Lan i210
Test jumper JP_LAN2, and setting 1-2 then power on.
It can see i210 operation under windows 10.
Test finish, shunt down windows.
I will setting 2-3 at JP_LAN2. => Power on => But still can see i210 operation under windows.
I need disable i210 after shunt down windows again.
What does mistake in circut or i210 code ?
Best regards,

Hello, wupatrick:
Thank you for contacting Intel Embedded Community.
In order to be on the same page, could you please tell us if the affected units have been designed by you or a third-party company? By the way, could you please let us know how many units are associated with this condition?
Finally, could you please verify that you have followed the DEV_OFF_N pin guidelines stated in sections 5.2.6.1, 4.4.4, 3.7.8.5.7, 4.4.2, 5.4.3, and 12.8; on pages 162, 144, 124, 143, 165, 836, and 837 of the https://www.intel.com/content/dam/www/public/us/en/documents/datasheets/i210-ethernet-controller-datasheet.pdf Intel(R) Ethernet Controller I210 Datasheet document # 333016?
Waiting for the information that should answer these questions.

Hello Carlos,
Thank you for your information!
I try to complete verification, and followed the guidelines stated of the document # 333016.
Still get same result
But i210 have another problem.
When Power is ON
I setting JP_LAN2 1-2 to 2-3 => shunt down => i210 ensure disable
It needn't shunt down again! (JP_LAN2 2-3 to 1-2 same result).
By the way, the APM Enable (Word 0x24) function. I need setting to 0b, when use Device Off function?
Best regards,

Hello Carlos,
My design source form Intel® Ethernet Controller I210-AT/I211-AT: Schematics. https://www.intel.com.tw/content/www/tw/zh/embedded/products/networking/i210-at-i211-at-1g-base-t-reference-design-schematic.html https://www.intel.com.tw/content/www/tw/zh/embedded/products/networking/i210-at-i211-at-1g-base-t-reference-design-schematic.html
Schematics mostly the same with reference schemaric pdf file.
Only dec_off_n function have used jumper setting to change pull-high or pull-low.
Controller ON or OFF i210-AT device.
I was review i210 datasheet, and found "asynchronous" on table 2-8.
What does this mean?
As stated before, change jumper 1-2 or 2-3 under OS.
Next restart system, then function was normal operation (can enable/disable i210) .
Can tell me this operator was sure?
It dev_off function in connection with intel Management Engine?
Thanks~
