PX-2300R Side View

 

 

 

PX-2300R modem has front-panel mounted RJ45 and USB for connection to the computer for 
SpectraSmart diagnostics and an RJ45 connector for the RS-485 interface to other PX-2300R modems.   
 
There are two different methods for interconnecting the diagnostics of more than one master PX-2300R 
modem.  Figure 7-3 illustrates how the diagnostics from each modem are connected together.  If the only 
diagnostic card is the PX-2300R, this figure illustrates how to connect the diagnostics back to the 
computer (either via the RS-232 or USB ports).  If more than one master PX-2300R modem is housed in 
the same chassis, the diagnostic information communicates with each of the modems via the chassis 
backplane.  No other interconnect cables are required.   
 
If additional PX-2300R master modems are installed in expansion chassis, a cable as shown in Figure 6-
23 must be connected between one of the master modems in the master chassis (subrack) and one in 
the expansion chassis (subrack) (Cable type #2).  This cable acts serves to communicate the diagnostic 
information for each of the master PX-2300R modems with that in the master chassis (SR-2000/S1-PC).  
Also, since these modems are configured as master modems, jumpers 25-28 on each of the modems 
must be installed.
