7.3 Installing an RRU on U-steel

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