Whats the best way to resolve this alarm "RF UNIT RX CHANNEL RTWP/RSSI Unbalanced "
In most cases we dont see any corresponding degradation in site performance but this alarm regularly pops up.

Try to change RRU

How about RTWP performance?
If RTWP high this alarm can rise.
However you can check RTWP alarm threshold in M2000

Simply change the jumpers they are faulty...

Hi, probably you have jumpers crossed between the main and diversity, open the LMT and then go to the monitor tab, and find an option that is called Board RTWP, find the RRU board number and then yo can see if the rtwp between both ports is unbalanced. if the difference is too much you have your jumpers crossed, try discarding first the jumpers coming from antenna , later the filter (if you have) and finally the RRU.
cheers

We have experience this before, found out to be cross jumper installation during cable regrooming activity
