Problems using the Rode NTG 3

I just acquired a Rode NTG-3 microphone to use with a Zoom H4n for an upcoming project. However I cannot seem to get the Mic to work. I have the Zoom set to 48v phantom power but the mic simply isn't registering. Is there something ive missed? Is there a way to check if the mic is faulty? Any help on this would be greatly appreciated, thank you.

Im using an XLR

Ah, I have it working now! I believe it was the cable that I was using that was the issue. Thank you very much for your help!
