Issue Draft B (2018-05-15)
Use an M6 Phillips screwdriver to loosen the screw on the sheet metal tab closer to the
handle of the second RRU. Then, rotate the sheet metal tab to align the vacant hole in the
sheet metal tab with a hole on the top of the first RRU.
Insert the removed screw into the hole on the top of the first RRU and use an M6 torque
screwdriver to tighten the screw to 5 N· m (44.25 lbf· in.).
Do not stand an RRU upright because the RF ports cannot support the weight of the RRU.
Place a foam pad or cardboard under an RRU to protect the RRU housing from damage
during the installation.
