eRRU Installation Modes
a
Common Requirements
CAUTION
• In all scenarios, the eRRU must be installed vertically.
• Do not stand the eRRU upright because the load-bearing capacity of the RF ports at the bottom of the eRRU is low.
• Place a foam pad or cardboard on the ground to protect the housing of the eRRU from damage before the binding.

Installing the Mounting Kits on the Wall
NOTE
• For a single RRU, the wall can bear four
times of the weight of an RRU.
• Expansion bolts must be tightened to 30 N· m
to ensure that the bolts work properly and the
wall remains intact without cracks in it.
