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

Procedure
l Side-mounted installation
CAUTION
To ensure that the cabling cavities of the modules face outwards, the module on the left must be installed in reverse mode while the one on the right must be in ordinary mode.
1. Remove the plastic housing of the RRU3804 that needs to be installed in reverse mode, as shown in Figure 3-36.
Figure 3-36 Removing the plastic housing
CAUTION
If you need to put the plastic housing face down, lay cardboards or packing bags on the ground first to prevent the plastic housing from being scratched.
2. Turn the module over, and then fix the housing to the module, as shown in Figure
3-37.
