7.2.2.7.3 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 or reverse 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 Hoisting an RRU onto a Tower.
• The hoist clamp on the main bracket is secured properly.
NOTICE:
• Do not stand an RRU upright because the RF ports cannot support the weight of the RRU.
• Place a foam pad or cardboard under an RRU to protect the RRU housing from damage during
the installation.
Context
Figure 1 shows the top view of an RRU installed on U-steel.
NOTICE:
When the width of the narrower edges of the U-steel is less than 40 mm (1.57 in.), only the a and b
modes are supported.
