Configuration

The following subsections describe your options in preparing the SLW2500 for service in the

distribution system.

Forward Path RF

For forward path operation, the SLW2500 lid motherboard (LIDB) houses a single optical

receiver, SG2-LR, in the receiver A position.

Forward Bandsplit Option

To use the forward bandsplit option, you must purchase an additional SG2-LR optical receiver

module and the SG2-FBS jumper board.

The broadband optical receiver module, SG2-LR, must be installed in the optical receiver A

position. The optional narrowcast optical receiver module, SG2-LR, must be installed in the

receiver B position. A forward bandsplit, SG2-FBS jumper board or JXP must also be plugged

into the LIDB. Figure 3-1 illustrates the location of the two SG2-LR receivers.

The SG2-LIDB distributes an RF signal from the receiver to the RF chassis as illustrated in

Figure 5-4:
