Determine a position for installing the pRRU. Then, place the separate mounting kit onto
the pole, thread the hose clamp through the mounting kit, and encircle the pole with the
hose clamp, as shown by illustrations a, b, and c in Figure 8-16.
Use an M6 inner hexagon screwdriver to tighten the bolt on each hose clamp to 5 N· m to
secure the mounting kit, as shown by illustration d in Figure 8-16.
It is good practice to connect one end of an Ethernet cable to the CPRI_E0 port on the pRRU before
the pRRU is installed.
It is good practice to perform the installation from the side view to promptly align the hooks with the
mounting holes.
