Paragon II’s channel port capacity can be expanded by installing a cascade of Base Units.  In a “two-tiered” 
cascaded system, one or more subsidiary Base Units are connected to the channel ports of a master Base 
Unit. If you fully populate a second tier, you can add a third tier by connecting additional subsidiary Base 
Units to the channel ports of Base Units in the second tier. Three tiers is the maximum depth of a cascaded 
system; only CIMs may be attached to the channel ports of Base Units in the third tier. A three-tier system 
can accommodate up to 2048 CPUs. 

 

1.  Connect one end of a CAT5 UTP cable to user port #1 on the back of the master Base Unit. Connect 

the other end of the cable to the RJ-45 CAT5 port on the back of the User Station. Connect a PS/2 
keyboard, PS/2 mouse, and VGA monitor to the User Station. Do not plug in or turn on the User 
Stations or monitors yet. (Do not attach anything to the Base Unit’s channel ports and do not plug it in 
or turn it on yet.) 

2.  For each subsidiary Base Unit you want to attach directly to the master, run CAT5 UTP cables from 

consecutive channel ports on the master Base Unit to the subsidiary Base Unit’s user ports. 

3.  If you are installing a third tier: Run CAT5 UTP cables from consecutive channel ports on a second-

tier Base Unit to the user ports on a third-tier Base Unit. Repeat for all other subsidiary Base Units in 
the third tier. 

4.  Follow step 5 of Installing a Paragon System with a Single Base Unit to attach CIMs and CPUs to 

the channel ports of any third-tier Base Units, any free channel ports on your second-tier Base Units, 
and any free channel ports on your master Base Unit. 

5.  Following step 1 of Installing a Paragon System with a Single Base Unit, plug in and power ON any 

third-tier Base Units, then plug in and power ON second-tier Base Units, then plug in and power ON 
your master Base Unit. Following steps 2b, 2c, and 2e of Installing a Paragon System with a Single 
Base Unit, plug in and power ON your User Stations and monitors. The master Base Unit should 
automatically recognize the connected subsidiary Base Units and update its configuration. All monitors 
should display the Login Menu. If any monitors instead display a “.....No connection to Paragon.....” 
message, the User Station they are attached to is not properly connected to the master Base Unit. 
Check for loose connections and make sure you are using good, intact CAT5 cables. (See Appendix A: 
Specifications for UTP-cabling information.)
