The ALD link is broken - PROBLEM

[sonerss]

Hi

I have got a problem with RCUs, We use Huawei 3g RAN12 and use DBS3900 cabinets. And use Kathrein and Powerwave antennas. But some of the NodeBs have got "The ALD link is broken" alarm. We have done physicaly check the ALD link and nothing found. Have you got an experinces about this problem...

First check what did you enter on the SET ALDPWRSYSCFG command. When you enable the switches set the TMA or in case you don't have a TMA then use multicore (directly on teh RRU). If you power it corectly it should work.
SCN ALD to get the serial

When you add the ALD device use sector splitting for powerwave antennas and use the serial numbers.
On kathrein it can work without the serials too.

If you need more explanation tell me.
