Installing the Two RRU3804 Modules
This describes how to install the two RRU3804 modules on a metal pole. The procedures for installing the modules in pole or wall installation mode are the same.
Prerequisite
l The RRU3804 mounting plate is installed.
l If the RRU3804 needs to be installed on a metal pole, the PGND cable of the metal pole is
connected.
Context
Two methods can be used to install the mounting plates on the metal pole. Accordingly, you can also install the two modules by using the following methods. Select a proper method depending on the installation of the mounting plates.
l Side-mounted installation
l Rear-mounted installation
