“RF Unit VSWR Threshold Crossed” alarm Troubleshooting in RRU Site

we need to remake the connectors of RRU jumper cable (I connector).If still alarmis not cleared then we need check the VSWR value and DTF (distance to fault) by site master. If problem found in RRU port then we need replace the RRU. For this alarm, the VSWR led will be blinking.

Very important Alarm.
