Do not stand the RRU upright because the RF ports cannot support the weight of the RRU.
Place a foam pad or cardboard under the RRU to protect the RRU housing from damage
during the installation.
A maximum of two, three, four, or six RRUs can be installed on a pole. When four or
more than four RRUs are added on a pole, the RRUs are installed vertically at different
levels and in different directions, and the length of the pole must be greater than or equal
to 1.5 m (4.92 ft).
Install RRUs with the same exterior by referring to the section "Installing Three or More
RRUs"in a related RRU installation guide.
This chapter describes the procedure for adding RRUs with different exteriors and uses
the procedure for adding five blade RRUs to a non-blade RRU in a live network as an
example.
Instruct the network management system (M2000/U2000) administrator to block the
RRUs.
On the UMTS side, log in to the LMT and run the BLK BRD command to block the
RRUs.
On the LTE side, log in to the LMT and run the BLK BRD command to block the RRUs.
