Figure 8-26 Installing a pRRU on a plate
Before installing the pRRU, connect one end of the Ethernet cable to the CPRI_E0 port on pRRU.
It is good practice to perform the installation from the side view to promptly align the hooks with the
rotation axis.
g. Use T20 with hole screwdriver to lock the protection screw on the attachment plate.
See Figure 8-27.
The protection screw protects the pRRU from being removed and must be locked if
required.
