Installing a Cascaded Paragon System
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.

Note: When powering ON existing stable configurations (i.e., if you are NOT replacing or adding
switches and NOT swapping the order of switches) or when you are Power Cycling a cascaded
configuration, Raritan recommends that you 1) Power ON the third tier switches (if a third tier
exists), then 2) Power ON the second tier switches, and 3) Power ON the Paragon II base unit.
User Stations can be powered ON and OFF at any time as needed.

Please note that this order is the reverse of upgrading a cascaded configuration: when
upgrading, first 1) Power ON the base tier, then 2) Power ON the second tier, and 3) Power ON
the third tier (if a third tier exists).

For configurations where switches are added, replaced, or swapped (in order), we recommend
Powering ON starting from the third tier, moving to the second, tier, and then the base tier, and
in addition, performing a partial reset of the database.

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 RJ45 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.

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.
