connect them to the RF interfaces on the front panel. However, re-cabling is required
for a base station to be expanded in capacity. Note that the RF cables are attached with
labels at both ends. The details are as follows:
1. The upper end (DIN connector) of the 1/2'' feeder from the RF front end to the
rack top has been installed to the rack top before factory delivery, so the onsite
installation only involves its lower end. During the installation, remove
dustproof cap from the lower end (N-type connector) of the feeder, hold the
lower end and slightly push the middle part of the feeder so that the feeder bends
naturally and its lower port aligns to the ANT port on the front panel of RFE,
and then fasten the screw cap. Please be noted that during the installation you
should align both the port and the screw cap to smoothly screw tight the 1/2''
feeder because it is short and has a certain rigidity.
2. Fig. 7.1-1 shows the structure of the RF connection lines between RFE, HPA
and TRX. The cables have all been deployed for the rack before factory delivery
if the base station is newly built. During the installation, open the baffle of the
cabling slot on the front panel and take out the connectors (SMA) and connect
them to the corresponding positions against the labels on the cables. For the
specific content of these labels, please refer to the information about "End A
Direction" and "End B Direction" given in Table 7.2-1, Table 7.2-2, Table 7.2-3
and Table 7.2-4 concerning the "Front Panel Wiring List" of multiple
configurations. Please also be noted that you should check the connectors
against the cable labels once again after installing them.

3. Some additional RFE, HPA and TRX modules are needed for a base station
requiring capacity expansion. The RF cables connecting them need onsite
connection. To do so, you should select the RF connection cables according to
the configuration requirements of the base station to be expanded, deploy the
feeders tidily and bind them securely inside the cabling troughs in accordance
