NOTE
l Place a foam pad or cardboard under an RRU to protect the RRU housing from damage during the
installation.
l Do not stand the RRU upright because the RF ports cannot support the weight of the RRU.
l The bolts used for installing an attachment plate on one side of an RRU are the bolts removed from
the attachment plate at the rear of the RRU.
Use a hex key wrench to remove the attachment plate from the rear of the RRU.
Optional: Remove the cover plate from one side of the RRU, and use a Phillips screwdriver
to remove the plastic screws from the RRU.
NOTE
The plastic screws of some RRUs do not need to be removed.
