Installation Installation Material In addition to industry standard tools, you will need the materials described in Table 2-1 during the installation. Item Description Table 2-1 Support Materials DC cord The diameter of DC power cable must be AWG14 or greater
(such as AWG13) with two cores. Ethernet cable Outdoor CAT6, shorter than 100 meters (~109 yards) Optical fiber Ground cable Optical fiber (armor) It is suggested that the diameter of the cable is 71mm. The diameter of grounding cable must be 10mm2 or greater. 5 Installation Tool Leveling instrument Marker pen Percussion drill hammer Knife Vise Wrench Cross screw Cable vice Tape measure driver NOTE: Other accessories have been packed in the packing box. Install GPS Antenna Read the following GPS antenna installation requirements before installing it on the base station. No major blocking from buildings in the vicinity. Make sure the space atop is at least 45 degrees unblocked by any buildings. Avoid installing the GPS antenna in the vicinity of any other transmitting and receiving devices, to avoid interference. The GPS antenna should be installed within 45 degrees to the lightning rod. The GPS antenna system is assembled in manufacturing before packing. The only installation step is to fix the GPS mounting bracket on the base station with the M4*14 screws. NOTE: The base station may adopt different models of GPS antenna, so the GPS antenna may not the same as above figure. But the installation steps that fix it on the base station is the same. Weatherproofing To protect the connection points from weather and climate, clean each connection point before installing cold shrink tubes, per the following figure. 1. Insert the cable into the cold shrink tube. 6 2. Tighten the connector. 3. Push the cold shrink tube to the top joint, and pull out the strip. 4. Ensure the cold shrink tube is tightly fitted with the connection. Pole Mounting Check to ensure the diameter of the pole is in the range of 1.6 inches to 2.8 inches (40mm to 70 mm). The position of the gNB on the pole should be at least 47 inches (120 cm) in height. The brackets have been pre-assembled in manufacturing before packing. It includes two parts, one is pre-assembled on the back of device. The other is for pole mounting or wall mounting, as shown in Figure 2-1. Figure 2-1 Pre-assembled Device Following will introduce how to fix the pre-assembled gNB on a pole. 7 After mounting, adjust the gNB to a proper angle by adjusting the adjustable bracket. Wall Mounting NOTE: The wall must bear at least 4 times the weight of the gNB. Take apart assembly bracket first, only remains the wall bracket, as shown in Figure 2-2. Figure 2-2 Wall Bracket Following steps introduce how to fix the pre-assembled gNB on a wall. 8 Connect Cables Power ON Power on the gNB, and wait a few minutes while the gNB boots up. Per the previous indicator description in 1 Appearance, check that the LED indicators are lighting as expected. 9
