You need to look at the data sheet, for the connector, and see if there are any directions. The manufacturer could, surely, help you. Feel free to call them. It is typical, for designers to check with them.
An easy method is to put the connector on the Eagle board, where you think it will go, print the board layout, at 100% scale, and match the actual component, to the board. You should do this, as a part of your regular design practice, anyway.
