Installation and maintain
1) Installation
1. The power supply should be installed in a place with good ventilation, shade and good heat dissipation;
2. Keep a certain distance between the power supply and other equipment for heat dissipation;
3. Fix the attached mounting bracket or hoop on the micro power supply device.
4. Fix it on the utility pole or base station bracket by wall hanging, pole holding, flag installation and other installation methods (when installing, the incoming and outgoing wires should be facing down to better waterproof), and tighten the fixing bolts.
2) Maintain
| No. | Symptom | Cause Analysis | Approach |
| 1 | Voltage does not work after power on | Whether the input air switch or terminal has voltage coming in, and whether the voltage value is within the normal range | Check if the voltage at the incoming line is normal, confirm that the air switch is closed |
| 2 | Keep restarting after power on | The rear stage load is too large | Whether the output is normal under the no-load test, if the load is too large, some devices should be removed |
| 3 | Communication equipment does not work after power on | Communication equipment such as RRU is powered by -48V and must have correct polarity to work properly | Reverse output cable polarity |
