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.
