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.
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 36 for correct card placement. Table 9 describes the name of each type of card in the
Digital shelf.
Tighten the screws to secure the RF/PA’s 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 43 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.
