Figure 3 Installing a downtilt supporting arm onto the lower handle Page 10 Figure 4 Installing the lower main bracket onto the AAU Installation Introduction—Installing a Main Bracket Installing an Upper Main Bracket onto a Pole Procedure Step 1 The installation technician puts the fixed pulley into a tool kit and then climbs up with the tool kit and a lifting sling. The assembled upper main and auxiliary brackets can be carried by the installation technician or be lifted onto a tower, as shown in figure 5. Step 2 Mark the position on the pole for installing the upper main bracket according to installation clearance requirements. Step 3 Adjust the positions of the M10 nuts on the two bolts according to the diameter of the pole, and loosen the bolts. Move the auxiliary bracket, horizontally slide the upper main and auxiliary brackets onto the pole, and partially tighten the bolts of the auxiliary bracket to the main bracket, as shown in figure 6. Figure 5 Binding upper main and auxiliary brackets Step 4 The installation technician standing in a proper position on the ground uses a compass to determine the azimuth (the azimuth is set to 120° as an example in this case), and the climber adjusts the azimuth according to the onsite requirements, as shown in figure 7. Step 5 Use an M10 torque wrench to tighten the two M10 bolts onto the upper main bracket to 40 N·m so that the upper main and auxiliary brackets are secured onto the pole, as shown in figure 8.

HISILICON SEMICONDUCTOR Page 11 Figure 8 Securing the upper main and auxiliary brackets onto the pole Installation Introduction—Lifting an AAU (1) Lifting an Assembled AAU onto a Tower Lifting an AAU onto a Tower/Rooftop Procedure for Binding an AAU Step 1 The installation technician on the ground binds the lifting sling, as shown in figure 9. 1) Wind the end of the lifting sling with the cramp ring round the attachment plate of the upper handle of the AAU. Do not wind the lifting sling round the outer beam of the attachment plate. 2) Open the cramp ring, clasp the lifting sling to the cramp ring, and close the cramp ring. Step 2 The installation technician on the ground uses the traction sling to securely bind the lower handle of the AAU, as shown in figure 10. Figure 9 Binding the lifting sling Figure 10 Binding the traction sling HUAWEI TECHNOLOGIES CO., LTD. HISILICON SEMICONDUCTOR Step 1 Lift the AAU. 1) If a winch is used, installation technician A operates the winch and installation technician B pulls the traction sling outwards to protect the AAU from colliding with the tower, as shown in figure 11. 2) If no winch is used, installation technician C pulls the lifting sling downwards, and installation technician B pulls the traction sling outwards to protect the AAU from colliding with the tower, as shown in figure 12. Step 2 When the cramp ring is close to the fixed pulley, the climber straightens the AAU upright and hooks the AAU downtilt supporting arm into the slots of the upper main bracket, as shown by illustration a in figure 13. Install the bolts on both sides of the upper main bracket into the holes and tighten them to 40 N·m, as shown by illustration b in figure 13.

Step 2 Secure the fiber optic cables vertically onto the tower using cable clips. Note: After climbing up to the tower, installation technician A secures the fixed pulley onto the tower platform support and leads the lifting sling through the fixed pulley. Installation technician B places the cable coiler for coiling fiber optic cables on the fiber spools. Installation technician D leads the lifting sling through the stretch sling of the fiber optic cables and uses the other sling as a traction sling to secure the cables at 4 m away from the lifting sling knot, as shown in figure 19. Step 1 Lift the power cables, as shown in figure 20. Step 2 Secure the power cables onto the tower vertically using cable clips. Note: After climbing up to the tower, installation technician A secures the fixed pulley onto the tower platform support and leads the lifting sling through the fixed pulley. Installation technician B secures three cable ties below the power cable connector to secure the power cable onto the lifting sling, as shown in figure 21. Installation technician B wraps the power cable connector with a layer of PVC insulation tape, as shown in figure 22.

HISILICON SEMICONDUCTOR Page 16 Installation Introduction—Adjusting the Mechanical Downtilt Mechanical Downtilt Adjustment When the downtilt supporting arm is installed onto the upper handle, the adjustable range is 0 to 20 degrees. When the downtilt supporting arm is installed onto the lower handle, the adjustable range is –20 to 0 degrees. The method of adjusting the mechanical downtilt when the downtilt supporting arm is installed onto the upper handle of an AAU is the same as that when the downtilt supporting arm is installed onto the lower handle of the AAU. This section describes the former one. The figure on the right shows a downtilt supporting arm installed on the upper handle of an AAU and a downtilt supporting arm installed on the lower handle of an AAU. Figure 29 Adjusting the mechanical downtilt based on the scale on the support for the downtilt supporting arm Procedures for Adjusting the Mechanical Downtilt by Using the Inclinometer Step 1 Loosen the six bolts on the attachment plate of the downtilt supporting arm and the AAU mounting kits to the adjustable status (Do not remove the bolts), as shown in figure 29 on the right. Step 2 According to the scale plate, adjust the downtilt supporting arm to an angle close to the required angle, as shown in figure 29. Step 3 Place the inclinometer on the AAU and check whether it is adjusted to the required angle. If not, adjust the angle of the AAU until the angle displayed on the inclinometer reaches the required angle. Step 4 After the mechanical downtilt is adjusted, use a torque wrench to tighten the bolts loosened in Step 1 to 40 N·m. Step 5 Remove the inclinometer from the AAU and pack it up.
