If RED led is illuminated, it means power supply is available at module. BTW which is controller? Have you check control card? Is the new module OK? Probably new LT module which you used might be defective.

Please check above points. 

 I suggest you replace Control card instead of  power section. control card such as 6SN1118-0DG23-0AA1

the alarm showing the #6 logical drive control card defective --there must be red led on that card

you can exchange 2 control cards in the same parts# for troubleshooting.

Respectively sir 

We have Power module 65N1123-1AA0D-OLA2(old) we replace 65N1123-1AA0D-OLA3 (new) after replace we getting alarm module 6 not found 30006 alarm We we reconnect all control wire but same alarm. Please suggest. And X 34 Red light on control card.

------------------------------------------------------------------------------------------
Split from 6SN1123-1AA00-0LA2 vs 6SN1123-1AA00-0LA3 .

I suggest you post now topic to SINUMERIK CNC automation branch. Give the detail story of your machine history.

Such as your machine is running good yesterday and you have some alarm , then your replaced drive, and so on

Or you purchase a 2nd hand machine , which coming with fault, you want to fix it , so you replaced everything 

That deepens on you , the more detailed information your giving the better help  will be given

Happy holiday
