epmp4500L faulty chain?

Hello,

We are experiencing the following issue with a 4500L unit:
On one of the chains, the transmit power has decreased (ceased entirely).

We tried swapping the cables and also cross-connecting them. Swapping had no effect, but after cross-connecting, the signal levels on the customer side switched places.

Do you guys perhaps have any idea what might be causing the issue (hopefully it’s not a radio problem, as replacing it would be quite cumbersome)?

Thanks

Hi @creed23 ,

unfortunately it sounds like a HW issue.
Could you Raise Ticket in the top right corner of this page and PM me the ID?
We will RMA this unit.
