Connect RF Cables & Alarms to BTS
Connect all of the cables to the BTS. The connection points are shown in Figures 39, 40, 41, and
42. Torque the cable connectors to 20-24 inch-pounds. If applicable, connect the cabinet alarm
connector and Battery Backup connector (Cabinet Alarm and BBU) to the back of the chassis.
More information on connecting alarms, rectifiers, and battery backup equipment are provided in
Appendix P and Appendix J, respectively.

Omni Antenna
The RFS Omni antenna is installed on a structure, such as a tower or a pole, which is defined in
the site survey and design. Following are the steps to complete the installation of the panel
antenna. Refer to the Regulatory Information in Chapter 1, Page 8 prior to installing.
Assemble the Antenna Mount per the instructions that come with it (Figure 43). Use a compass
to determine which direction is true East (incorporating declination angle - see Figure 31).
Figure 43: Omni Antenna Mount
Mounting Hole Pin
Position the Antenna Mount in a direction to provide accessibility to the RFS after it is installed.
Position and install the Antenna Mount on the mounting structure so that any one of the eight
mounting hole pins is facing East. Tighten the Antenna Mount hardware to secure it to the
structure (Figure 44).

Sweep the RFS antenna inputs for dB loss. Record all results for later calculations. Position the
RFS on the Antenna Mount, ensuring that the arrow on the bottom of the Antenna Mount faces
true East. Secure the RFS antenna to the Antenna Mount (Figure 45). Install surge protectors on
the 8 antenna and 1 cal connectors.
Figure 45: Omni Ground Stud
Ground Stub
Connect the eight antenna cables, cal cable, and Data/Power cable to the RFS antenna. Attach the
ground wire to the ground stud. Install grounding kits from RF cables to buss bars. Sweep the
antenna and cables from the RF cable connectors that attach to the BTS. Record all
measurements. Weatherize all connections (Figure 46).

Verify Installed Circuit Cards
WARNING! Ensure that power to the BTS chassis is off before installing the
circuit cards or any of the RF Power Amplifiers in the chassis.
FUSES ARE NOT FIELD-REPLACEABLE. In case of need to replace a fuse on a CHP (F1),
CC (F33, F17-32), SYN (F3), MDM (F1) or PA (F1) contact Navini Networks Technical
Support
CAUTION! For continued protection against risk of fire, replace only with the
same type and rating of fuse.
ATTENTION! Pour ne pas compromettre la protection contre les risques
d’incendie, remplacer par un fusible du même type et des mêmes caractéristiques
nominales.
CAUTION! - Please contact Navini Technical support before attempting to
exchange cards between chassis of different type and frequency to verify
compatibility.
The circuit cards, including the RF/PA cards, normally come seated in the BTS chassis. If they
are already installed, verify that the correct cards are placed and seated properly. The RF/PA
modules may be installed in any position on the top (RF) shelf. For the Digital shelf, refer to
Figure 47 for correct card placement. Table 4 describes the name of each type of card in the
Digital shelf.
Tighten the screws to secure the RF/PAs into the RF shelf. For the circuit cards, follow the
markings on the backplane for the position of each card in the Digital shelf. Make sure the
ejectors on all cards are engaged in the chassis. Figure 46 represents a fully populated Digital
shelf. If the BTS is not fully populated, blank panels are installed to fill in the empty card space.
They are also used to fill in the empty space between the circuit cards and the end of the cabinet.

Base Station Installation Certification
When the installation of the equipment is complete, the Base Station Installation Certification
form needs to be completed and signed off by both the installer and the customer. A copy of this
form may be found in Appendix T.
