to retain all user and system profiles, and to auto-detect the current
status of its channel ports and user ports. Follow the installation
steps in this section to install the new cascade, but when you turn
on each switch (which must be done in proper tier order, from
upper tier to base tier), press FUNC on the unit's front panel until
"Clear Database Hit Ent/ESC?" appears on the LCD panel. Press the
ENT and the ESC buttons sequentially to execute a partial reset on
the database. For information on partial reset, see
Reset Unit
(on
page 44).
Guideline for Turning On a Cascaded System
When turning ON existing stable configurations (that is, if you are
NOT replacing or adding Paragon switches and NOT swapping their
order), or when you are power cycling a cascaded configuration,
follow this sequence:
1. Turn ON the third tier (if a third tier exists).
2. Turn ON the second tier.
3. Turn ON the base tier (first tier).
For configurations where Paragon switches are added, replaced, or
swapped (in order), follow this sequence:
1. Turn ON the third tier (if a third tier exists).
2. Turn ON the second tier.
3. Turn ON the base tier (first tier).
4. Perform a partial reset of the database on impacted Paragon
switches. For example, if you swap the switches connected to
the base tier, perform the partial reset on the base tier. If you
swap the switches connected to the second tier, perform the
partial reset from the second tier to the base tier. For information
on partial reset, see Reset Unit (on page 44).

Installing a P2-UMT832S Stacking Unit
1. Turn OFF all Paragon switches, including the Main Unit and Stacking
Unit.
2. Connect a power cord to a Stacking Unit.
3. Connect one end of a stacking cable to "Expansion Port Out" on the
back of the Stacking Unit. Connect the other end of the cable to
"Expansion Port" on the Main Unit.
4. (Optional) To cascade more than one Stacking Unit, connect one
end of another stacking cable to "Expansion Port In" on the back of
the Stacking Unit and the other end of the cable to "Expansion Port
Out" of another Stacking Unit. For P2-UMT832M, up to 3 Stacking
Units can be cascaded.
