Checkups before Power-on Purpose After installation, microwave equipment must be checked again (after installation acceptance) before power-on.

Preparation Commissioning preparations are complete.

Step Figure 3-1 shows the checks before power-on.

Figure 3-1

1. i.

Checkups before Power-on

Power supply check Before the measurement, ensure that switches of the power module and the fan module are all OFF.



6



ii.

Measure input polarity of power supply to ensure that there is no short circuit. Marks of the power terminals should be proper without mistake. Protective grounding should be connected properly. Switch on the power supply after all checks above are passed.

iii.

Measure voltage of power supply, check polarity correct and power supply located in the permitted range or not (DC nominal voltage is -48V, and the permitted range is located in -40V - -58V).

During the test process above, in case of any abnormity, cut off the power supply immediately and find out the fault causes.

Note: All operations that related equipment must be perform with antistatic wrist strap. Grounding should be well done. When inspect all kinds of power supply, pay attention to the on-off status of every switch and circuit breaker to avoid electric shock. 2.

Hardware installation check i.

Rack installation check

−

Check whether installation of rack and modules looks good and neat.

−

Check whether all screw of every modules are tightened.

−

Check whether cables are lined following the specifications.

−

Check whether labels are unified and clear, and are easily identified.

ii.

IDU and boards installation check

−

IDU installation check Check whether IDUs are installed in the correct positions and whether screws are tightened.

−

Boards installation check Usually, boards of ZXMW NR8250 (V2.03.02) IDU have been installed and debugged before delivery, so there is no need to operate on site. During field commissioning, check boards category, quantity and position in the IDU.

iii.

Antenna and feeder installation check Check whether antennas and feeders are matched. Ensure the installation is proper and antennas work correctly.



7


−

Installation of antennas and feeder cables are complete.

−

Check antenna and feeder connection.


Check whether feeder cables and connecters are damaged. Check the connecters. Check antennas direction. Check connection between antenna and feeder cables. −

Test procedure should be arranged compactly to avoid repeated connection and disconnection of connectors and other sealed parts. Sealing tape should not be used on connectors until test is completely finished. As electromagnetic emission exists in running equipment, do not stand close to the running antenna. Equipment can be only installed and maintained by specially trained personnel.

Warning: When operating on equipment with high-intensity RF (radiated frequency) signals, pay attention to the high-intensity microwave impact on human body. 3.

Cables installation check Cables include power supply cables, grounding cables, E1 cables, IF (intermediate frequency) cables and low loss cables. Each cable’s checkup should follow the requirements below: i.

Power supply cables Check whether power supply cables are connected stably with correct polarity.

ii.

IF cables

−

Check if there is open or short circuit in IF cables.

−

Check if IF connecters are made properly.

−

Check if the IF cable is properly connected to ODUs and IDUs.

−

Check if the outdoor IF cable connectors are well waterproofed.

iii.

Grounding cables



8


4.


−

Check whether racks grounding cables are installed correctly.

−

Check whether IDUs grounding cables are installed correctly.

−

Check whether ODUs grounding cables are installed correctly.

−

Check whether IF cables grounding cables are installed correctly.

iv.

Services cables

−

Check whether services cables are connected to the correct ports according to the engineering design.

−

Check whether services cables are lined correctly according to installation specifications.

−

Check whether labels on services cables are correct.

Check list before power-on Check results should be recorded into the table as shown in Table 3-1.

Checkups after Power-on Purpose After checkups before power on, follow the correct order to power on microwave equipment. In this step, parameters and settings are not configured. Therefore, checkups after power-on mainly focus on power supply status of IDU and the fan unit operation.

Preparation Power-on sequence of ZXMW NR8250 (V2.03.02) equipment: 1.

heck and ensure power switches of all modules are on the OFF position.

2.

Turn on the power switch of the power cabinet.

3.

Plug the power cables in to the power ports of the IDU.

Step After equipment power-on, check power supply status of the IDU. RUN LED of IDU boards should blink slowly. Check results should be recorded into the table as shown in Table 4-1.

Step Main lobe of microwave antenna is rather narrow. It is normally from 0.6 degree to 3.7 degree. For example a 1.2 m diameter 23 GHz microwave antenna, there is only 0.9 degree from signal peak to zero. During antenna adjustment, we need only to adjust slightly when signal is found. Main lobe and side lobe are shown as in Figure 7-3. We can decide whether main lobes of antennas are aligned properly by comparing the RSL peak value. Normally RSL peak value of the main lobe is 20 dB - 25 dB higher than that of the 1st side lobe. If main lobes of both ends are captured by the opposite end simultaneously, an error within 2 dB is acceptable.

Figure 7-3

Main Lobe and Side Lobe

If 1+1 HSB / FD protection and one antenna are adopted, shut down standby ODUs of both ends first and power on them after antenna adjustment is done. If 1+1 SD protection is adopted, antennas shall be adjusted as following steps.

−

Power on master ODUs of both ends and keep them active through the adjustment process.

−

Shut down standby ODUs of both ends and adjust master antennas.

−

Power on local standby ODU, keep the remote master antenna fixed and adjust local diversity antenna.

v.

Repeat operations mentioned in Step 2 to Step 4 for two to four times. Fix antennas of both ends when ODU voltage of both local and remote ends reach the highest value.

vi.

Measure ODUs voltage with the multimeter. Calculate the current RSL according to RSL and ODU voltage curve is shown as in Figure 7-4. This figure is for A400 ODU, and different ODU maybe with different curve, please refer to the product description of the actual installed ODU.
