Steps 1. Before the equipment is powered on, make sure that the powersupply's voltage is normal and the electrodes are correct.

2. Check whether the switch of the equipment's power supply isin OFF status.

3. Check whether the antenna feeder is installed correctly.

4. Check whether the cabinet, the antenna feeder, and the light-ning protector are grounded correctly.

5. Make the equipment power on: Firstly, make sure that thepower supply of all modules are turned off; secondly, put thepower supply's switch of the power supply cabinet to "ON", andput the power supply's switch of IDU to "ON".

6. Check the power supply of IDU: After the equipment is poweredon, check the power supply of IDU by observing whether IDU'spower supply indicator is in normal working status (i.e. greenand constantly ON).

7. Check the power supply of fan module: After the equipment ispowered on, the fan module of IDU should automatically start.



Put a small strip of paper at the fan's wind outlet. If the paperflaps, it indicates that the fan is working normally.

END OF STEPS

Logging in to WEB CITPrerequisites The equipment is powered on.

Context The notebook PC is accessed to WEB CIT through Ethernet cable.Check whether the notebook PC can be accessed to WEB CIT nor-mally. Such checking guarantees subsequent data configurationand other commissioning items that use WEB CIT.

Adjusting Antennas at BothEnds

Short Description Adjusting antennas at both ends is the most important testing itemin inter-site commissioning. This adjustment directly influencesthe microwave link's performance.

Prerequisites � The single site commissioning for microwave equipments atboth ends of the microwave link has been completed.

� During the commissioning process, the weather is fine betweenthe two sites, without rain, snow, or fog.

� The actual conditions and antenna commissioning personnel allsatisfy the requirement for working at high altitudes.

Steps 1. If the distance between the two sites is long (larger than 2km), then set antennas at both ends horizontally. If the dis-tance between the two sites is short, then adjust the antenna'sdowntilt within a small range according to actual condition.

2. Connect the multimeter with the local ODU's BNC port cor-rectly.

3. Adjust the antenna's horizontal position: Fix the remote an-tenna, measure the voltage at BNC port with the multimeter;rotate the antenna within a large range in horizontal direc-tion, and make sure that at least three peak signals of BNC arescanned within the rotating range, of which the middle one hasthe highest voltage.



4. Adjust the antenna's downtilt: Adjust the antenna's downtilt ateach position when BNC port has the peak volage to make thevoltage at BNC port reach the highest value within the scanningrange. Adjust the antenna to the position when BNC port hasthe highest voltage, and fix the local antenna. When tighteningthe antenna, keep the voltage at BNC port to be the highestvalue.

5. Adjust the remote antenna. Make the receiving level at theremote end to have the largest value, and fix the remote an-tenna.

6. Repeat the above steps for 2 ~ 4 times to make the receivinglevel at both the local end and the remote end have the largestvalue. Fix antennas at both ends.

7. Use the multimeter to test voltage at BNC port at both ends.Read the current receiving power according to voltage at BNCport of ODU at both ends and the Received Signal Level (RS)curve.

8. Fasten all screws of the antenna.

END OF STEPS
