Installation Position

If only the RRU is installed, the waterproof DB9 connector is linked to the RET/PWR_SRXU
port at the bottom of the RRU, and the standard AISG female connector is linked to the
corresponding connector on the RCU or to the AISG extension cable.

If both the RRU and the SRXU are installed, the waterproof DB9 connector is linked to the RET
port at the bottom of the SRXU, and the standard AISG female connector is linked to the
corresponding connector on the RCU or to the AISG extension cable.

2.4.4 AISG Extension Cable of the RRU/SRXU

When the distance between the RCU and the RRU/SRXU is longer than 5 m, the AISG multi-
wire cable is not long enough to cover the distance. In this case, the AISG extension cable is
used. The AISG extension cable is 15 m long.

Appearance

The cable has a standard AISG male connector at one end and a standard AISG female connector
at the other end, as shown in

Figure 2-18
