Equipment power supply

• MU and HUB require 110V AC power supply, and the preferred power supply method is to use the power line cut off method. This power supply method requires single-phase electricity (110V AC) to be extracted from the three-phase electricity in the distribution cabinet.
• If there is no power cord cutting method available on site, use a socket to take 110V AC power. The power socket must be at a height that is not easily accessible by ordinary people to prevent manual unplugging of the base station power plug.

Equipment grounding

1. Use the resistance range of a multimeter, with one probe connected to the device’s casing screw and one probe connected to the ground wire of the power socket. If the measured resistance value is relatively small (less than 10 Ω), it is considered that the device has good grounding performance. If the resistance value is too large, it can be investigated from the following aspects：
   • Eliminate the problem with the multimeter itself: short circuit the two probes of the multimeter and observe if the resistance value is zero; The resistance value is zero, and the multimeter is normal; Not zero, abnormal multimeter.
   • Is the screw for equipment grounding tightened.
   • Is the grounding wire broken.
2. Touch the device casing with an electric pen. If the electric pen light is on, it indicates that there is current in the equipment casing and there is a leakage situation. Need to check if the equipment grounding is standard.

Cable connection

• The fiber length insertion loss between MU and HUB shall not exceed 8dBo, and the 5D cable insertion loss between HUB and the farthest ARU shall not exceed 45dB.
• After the installation of MU, HUB, and ARU is completed, the installation interface needs to be connected and checked for accuracy before turning on the power and working normally.

Device identification

• Each device, as well as wall mounted boxes and meter boxes, should be labeled clearly for future management and maintenance. The labels should be pasted in a visible area on the front of the equipment and equipment. The labels for each cable (such as 5D cable, power cord, tail fiber, etc.) are affixed at 20mm away from the wire head at both ends for easy reading and future management and maintenance. The labeling should be neat and clear.
• The label of the device should be prominently placed on the device and not affect the overall harmony of the environment to maintain overall aesthetics. Warning signs must be attached to the host and power supply.
• When there are multiple devices or lines running side by side, the labels must be placed on the same horizontal line

Power on inspection

• After powering on, it is possible to observe whether the power supply, optical fiber, etc. are connected properly, and whether the optical fiber and 5D cable are normal can be confirmed through the device indicator light.

Routine inspection

• Equipment installation: Check whether the installation position of the equipment matches the design, and whether the installation is firm;
• Power supply installation: Check whether the power supply is normal and whether the installation process of the power cord is qualified;
• Site labels: Check if the equipment, power supply, and other labels are complete and labeled in a standardized manner;
• Cable continuity: Use an optometry pen to test whether the physical link of the tail fiber is normal;
• Equipment grounding integrity: Use a multimeter to test the resistance of the grounding wire to ground, etc.
• Other: After powering on, check if the relevant indicator lights are on, etc
