RUN Green Blinking (ON for 1s andOFF for 1s)

The PMU is functional, and thecommunication with the main control unit isnormal.

Blinking (ON for0.125s and OFF for0.125s)

The PMU is functional, but thecommunication with the main control unitfails. If the PMU does not communicate withthe main control unit for one minute, thecommunication fails.

ON or OFF The PMU is faulty (not in the power-on self-check state).

ALM Red ON The base station reports at least one of thefollowing alarms:l Mains overvoltage or undervoltage alarm

l Busbar overvoltage or undervoltage alarm

l Power module alarm

l Load shutdown alarm

OFF No alarm is reported.

NOTE

In 3s to 5s after the PMU is powered on, the ALM and RUN LEDs are simultaneously ON for about 3s.

DIP SwitchThe DIP switch is positioned on the right panel of the PMU. The DIP switch has eight bits, whichare set to OFF before delivery. Figure 5-4 shows the DIP switch.



5-9

Figure 5-4 DIP switch on right panel of the PMU

The bits of the DIP switch are in binary format. The four least significant bits (1, 2, 3, and 4) ofthe DIP switch define the secondary node address of the PMU. The four most significant bits(5, 6, 7, and 8) are not defined, and they are reserved for future use.

You can set the monitoring address by setting the four least significant bits of the DIP switch.The first bit corresponds to BIT0, and the fourth bit corresponds to BIT3.

NOTE

l When the BBU3900 is installed in the APM30, the monitoring address of the PMU must be set to 3,that is, the four least significant bits of the DIP switch must be set to 1100.

l When the BBU3806 is installed in the APM30, the monitoring address of the PMU must be set to 9,that is, the four least significant bits of the DIP switch must be set to 1001.

l Value 1 indicates that the bit of the DIP switch is set to ON, and value 0 indicates that the bit of theDIP switch is set to OFF.
