7.3 Installing the RRU on U-steel
This section describes the procedure and precautions for installing the RRU on U-steel. U-steel
can be installed either on the ground or a tower and only one RRU can be installed on a piece
of U-steel. An RRU on U-steel is installed in standard mode by default.
Prerequisites
Before you install an RRU on a tower, the RRU and mounting brackets are hoisted onto the
tower. For details, see
6.1 Hoisting an RRU onto a Tower
The hoist clamp on the main bracket is secured properly.
NOTICE
l
Do not stand the RRU upright because the RF ports cannot support the weight of the RRU.
l
Place a foam pad or cardboard under the RRU to protect the RRU housing from damage
during the installation.
