NOVA R9 1W not powering up

Any help?

I did a 375ft power cable run to the NOVA R9 1W, and this think will not power… I change the power supply from 48v to 54v still no luck.

The NOVA R9 1W eNB did power up when I tested it in my office before taking it to the tower.

Any suggestion?

Our one and only current site has a 115’ power run, so the only thing I can offer is that it may involve a climb with a multimeter to inspect the cable and test at the top end. :frowning:

Thanks
