You are in the wrong forum but i can help you
What you need to do is using the blue cable that came with the module !
Connect it to a free expansion port on the back of the ip500
check if you have a license called upgrade from standard to professional
Without it the module does not work !!!
Power down the ipoffice
Power up the module and then power uo the ipoffice
Change the working directory to the 3.2.999 folder
Upgrade the DS30
It needs the 3.2.999 bin file first
Then change your working directoy back to the manager folder
Then upgrade it to your 4.x version (4.2.14 is current)
Then there should be 30 more extension and users and you only need to configure them
