CHAPTER 2: INSTALLATION 19
Installing a Cascaded Paragon System
Paragon II’s channel port capacity can be expanded by installing a cascade of matrix switches
(Main Switching Units). In a “two-tiered” cascaded system, one or more subsidiary matrix
switches are connected to the channel ports of a Base Unit (first tier -- Master matrix switch). If
you fully populate a second tier, you can add a third tier by connecting additional subsidiary
matrix switches to the channel ports of matrix switches in the second tier. Three tiers is the
maximum depth of a cascaded system; only CIMs may be attached to the channel ports of matrix
switches 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
c
Power on the THIRD TIER switches (if a third tier
exists), then
d
Power on the SECOND TIER switches, and
e
Power on the Paragon II BASE TIER.
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
c
Power on the BASE TIER, then
d
Power on the SECOND TIER, and
e
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.
Figure 25 Sample Cascaded System
1. Connect one end of a CAT5 UTP cable to user port #1 on the back of the Master matrix
switch (Base Unit). Connect the other end of the cable to the RJ45 CAT5 port on the back of
the User Station. Connect a keyboard, a mouse, and a monitor to the User Station. Do not
plug in or turn on the User Stations or monitors yet. (Do not attach anything to the matrix
switch’s channel ports and do not plug it in or turn it on yet.)
2. For each subsidiary matrix switch you want to attach directly to the Master, run CAT5 UTP
cables from consecutive channel ports on the Master matrix switch to the subsidiary matrix
switch’s user ports.
3. If you are installing a third tier: Run CAT5 UTP cables from consecutive channel ports on a
second-tier matrix switch to the user ports on a third-tier matrix switch. Repeat for all other
subsidiary matrix switches in the third tier.
4. Follow step 5 of Installing a Paragon System with a Single Matrix Switch to attach CIMs
and servers to the free channel ports on the third-tier matrix switches, on the second-tier
matrix switches, and on your Master matrix switch.
