Installing a pRRU on a keel



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.

Step 6 Optional: Use T20 with hole screwdriver to lock the protection screw on the attachment plate.

The protection screw protects the pRRU from being removed and must be locked if required.
