This guide divides the installation procedure of each multiplexer into tabbed sections (see
). Follow the
procedures listed only within this tabbed section of the guide.
Figure 20.
Selecting the Proper Tabbed Section for Your Multiplexer
Before installing a multiplexer, verify that there are no cables plugged into P15 and P16 (Port 1)
at the rear of the chassis. If there are cables connected to P15 and P16 and they are not in use,
remove them. If the cables are in use, take them out of service and then remove them.
Leaving cables attached to P15 and P16 (Port 1) double terminates the DSX-1 interface and
causes it to malfunction.
