Figure 3-18 Cable connections of one RRU without the SRXU
NOTE
l When one RRU is installed, the PGND cable is connected to the grounding bolt on the RRU module.
l The AISG multi-wire cable connects the RRU to the RCU. When the distance between the RRU and
the RCU is too long, the AISG extension cable is used between the AISG multi-wire cable and the
RCU.
l The antenna jumper directly connects the RRU to the antenna. When the distance between the RRU
and the antenna is longer than 14 m, the feeder is required.
