the logical bridge between the
interface cards and the console-
generated commands. Order the
SM902C card for the SM900A
chassis and the SM904C card for
the SM901A chassis.
The Management Control Card
supports console-controlled data-
circuit alarming and includes a full
array of LED signal-status
indicators and voltage-test points.
With the card, switching
commands are received from
the PSSII and relayed to the
appropriate rackmounted circuit
cards. These commands can be for
individual circuits, all circuits within
a rack, or specific circuits that are
part of a user-defined circuit group,
whether they originate from a real-
time console entry or they’re
generated automatically when
an alarm occurs.
If you’re looking to configure
the chassis from various locations
while using an attached ASCII
terminal, you’ll need the Terminal
Display Card, available for the
RS-232, RS-530, X.21, V.35 chassis
(SM903C) or V.35-only chassis
(SM905C). With this card, you can
program the system to switch
circuits at a specified time—
automatically. This is a particularly
useful capability when, for
example, you need to redirect
incoming calls at the office at
a certain time of the day. You can
also use the Terminal Display Card
to control a group of the circuit
cards in a gang-switch capacity.
The Terminal Display Card
package includes the DB25 to
RJ-45 card, an RJ-45 to RJ-45
cable, and a DB25 to RJ-45 adapter.
Management software.
The Management Control
Software enables the PSSII to be
configured to place outgoing calls
and receive incoming calls from
sites equipped with one or more
PSSII chassis.
What’s more, the software
provides you with the ability to
examine any portion of your
enterprise network at any desired
level of detail. In addition, the
utility advises you of any major
occurrence anywhere within the
network.
The software’s interface
displays on-screen alarm
conditions with a date and time
stamp. A color-coded signal also
shows the status of any circuit in
the network, and you can view
signal status for an entire chassis.
The software’s Circuit
Configuration menu is the way you
assign circuits to and from
a ”group,“ which is defined as a
logical collection of circuits without
regard to their location within the
Pro Switching System II. All
switchable circuits within a
specific group can be switched
by either console command or
automatically upon alarm.
Manual Contact Closure Card
To provide both manual and
contact closure gang-switching
capabilities to your system, order
the Manual Contact Closure Card
(SM916C). This card enables you
to patch a programmable logic
controller (PLC) to the straight-
through Monitor interface
connector on the chassis. The PLC ,
in turn, is used to switch all circuits
in the chassis from A to B and back
again automatically.
Not only can you use the card
with a PLC to close contacts, but
you can disable specific cards
seated in the chassis using the
card’s DIP switches. To manually
reverse all switch positions in the
master chassis, you need only to
press a lamp-test button at the top
of the card.
Unlike other cards designed
for the PSSII, the Manual Contact
Closure Card does not support
terminal or PC management. It
has a signal-status LED display
and two patch cavities. The upper
cavity provides a straight-through
connection to the LED display and
to a DB25 I/A interface on the
chassis, while the other provides
a straight-through connection to
the Monitor interface connector.
Other PSSII components
For using external test
equipment with your Pro Switching
System II, order an optional 6-foot
(1.8-m) Test Cord. The RS-232
version (SM917) attaches the
system to RS-232 or RS-530
equipment, while the V.35 model
(SM918) attaches the system to
V.35 equipment.
For standard nonintrusive
testing, you would run the cord
from the bottom Monitor port patch
cavity on a PSSII chassis to the
DB25 or M/34 connector on your
test equipment. You can also use
the Test Cords for intrusive testing
that breaks the normal signal paths
and routes the Port A or B or
modem port signals to the external
equipment.
You’ll also need to equip your
chassis with one or two Power
Supply Modules (SM950A or
SM950A-220). Using two supplies
makes your system more reliable: if
one module fails, the other kicks
in to keep the PSSII operating as
normal. Failure of either Power
Supply Module will trigger a
console alert, although one module
can provide enough power to a full
chassis.
If you choose to use only one
Power Supply Module, be sure to
order a Blank Cover for an Unused
Power Supply Slot (SM911C). This
is a protective metal strip that fits
over the empty slot at the rack’s
rear and helps keep the chassis
internal parts free of dust and other
particles.
We also offer covers for
unused circuit card slots in the
rack. As with the SM911C, the
Blank Cover for an Unused
Interface Slot (SM910C) includes
screws for securing it to the
chassis. All empty module slots
on the chassis should be filled with
these blank panels. Doing this will
help to prevent damage from
occurring to the installed modules
and the chassis components.
