technical specifications.
Refer to the Release Guide and the online Release
Update for your Dialogic
®
system release software
to verify that the Dialogic
®

supported in the release and for information on any
new features or issues that may relate to it.
The Regulatory Notices document that is packed
with each Dialogic
®
D/120JCT-LS-EW board
contains safety warnings and national
requirements for proper operation of
telecommunications equipment.
2. Before You Begin
Protecting the Board from Damage
CAUTION:
All computer boards are sensitive to
electrostatic discharge (ESD). Handle all static-
sensitive boards and components at a static-safe
work area, and observe anti-static precautions at
all times.
If you are not familiar with ESD safety precautions,
visit http://www.dialogic.com/support/hwinstall to
learn more.
Unpacking the Board
Unpack the board according to the following steps:
1. Prepare a static-safeguarded work area.
2. Carefully remove the board from the shipping
carton and static-shielding bag. Handle the
board by the edges and avoid touching the
board's components.
3. Lay the board on the static-dissipative work
surface.
Note:
Place boards in static-shielding bags when
carrying boards from station to station.
CAUTION:
Do not remove the board from the
anti-static packaging until you are ready to install
it. Observe proper anti-static precautions at all
times.
3. Configuring the Board
The Dialogic
®
D/120JCT-LS-EW board uses Plug
and Play technology to simplify installation. No user
configuration is required for IRQ or memory
address.
The Dialogic
®
D/120JCT-LS-EW board has the
following manually configurable options:
■
Board ID
■
Hook-switch state during start-up
■
Power budgeting (see Choosing a Slot section
below)
Setting the Board ID
When the system is started, each Dialogic
®
telecom board is assigned a board instance ID
number that programs can use to identify
individual boards in a multi-board system. The
setting of SW100 controls the generation of the
instance numbers.
Windows Systems:
In a Windows system, leaving
SW100 set to the 0 position (the factory default
setting) on all Dialogic
®
telecom boards causes
the system release software to assign instance
numbers geographically, based on the bus and
slot numbers. Note that when using this method,
there is no way to know what the instance
numbers will be until the system is started and
configured, and the instance number for any
given board is likely to change when there is any
change in the number or arrangement of boards
in the system.
As an alternative, you may set SW100 on each
board to a different position (0-9 or A-F) to
explicitly assign specific ID numbers to the
boards. Note that each board must be set to a
different ID number.
In either case, you can read the ID numbers
assigned to the boards in the Dialogic
Configuration Manager (DCM) after you start the
system and invoke that tool.
Linux Systems:
In a Linux system, you must
explicitly specify the board ID numbers by
setting SW100 on each board to a different
position (0-9 or A-F). Refer to the Configuration
Guide for Springware architecture products in
your Dialogic system release software
documentation for further information about the
board ID numbers.
Setting the Hook-Switch State for Start-
up
Slide switch SW1 determines how the Dialogic
®
D/120JCT-LS-EW board responds to an incoming
call when the PC power is on, but the board is not
yet initialized.
When the SW1 slider is positioned away from the
board’s bracket, the Dialogic
®
D/120JCT-LS-EW
board responds as on-hook while uninitialized.
With the SW1 slider positioned closer to the
bracket, the board responds as off-hook during
start-up.
The factory default setting for SW1 is on-hook.
4. Choosing a Slot
The Dialogic
®
D/120JCT-LS-EW board is a full
length x1 form factor PCI Express board that
requires 25W of power. The following explanation
and guidelines are provided to ensure proper
configuration of the product.
Power Budgeting is a new feature, introduced in
the PCI Express Specification, that provides a
mechanism to enable a system to negotiate power
consumption requirements for add-in devices.
Per PCI Express Card Electromechanical
Specification Revision 1.0a or higher, a x1 add-in
card can draw no more than 10W in a x1 slot
unless the board’s required power is successfully
negotiated and allocated by the system (power
budgeting). However, implementation of power
budgeting by a vendor's system is not a compliance
requirement per the PCI Express Card
Electromechanical Specification Revision 1.0a or
higher. Therefore, some chassis may not support
this feature. Power Budgeting jumper P3 is
designed to ensure proper configuration of the
product.
The Dialogic
®
D/120JCT-LS-EW board must be
installed in a slot that can be allocated 25W.
If Power Budgeting is
not
implemented by a
vendor's system, the Dialogic
®
D/120JCT-LS-EW
board
must
be plugged into a x4 or higher slot
with the P3 jumper in position 1-2 (power
budgeting ignored). This is allowed per PCI Express
Card Electromechanical Specification Revision 1.0a
or higher because a x4 or greater slot must be able
to support a minimum of 25W.
If Power Budgeting is implemented by a vendor's
system, the Dialogic
®
D/120JCT-LS-EW board
can
be plugged into a x1 slot but the P3 jumper must
be in position pins 2-3 (power budgeting adhered
to).
WARNING! Installing the Dialogic
®
D/120JCT-LS-EW board in a x1 slot with the
P3 jumper in position 1-2 will void the
warranty of the D/120JCT-LS-EW board.
If the Dialogic
®
D/120JCT-LS-EW will be connected
to other telephony boards via a CT Bus cable, you
should install the boards to minimize unused
connectors on the CT Bus cable (in addition to
ensuring that the power requirements are met):
■
Install boards in adjacent slots whenever
possible.
■
If the Dialogic
®
D/120JCT-LS-EW board will be
connected to one or more PCI boards, use the
PCI Express slot(s) closest to the PCI slots.
5. Installing the Board
WARNING! Unplug the equipment before
performing the procedures described here.
Failure to disconnect the power before you
open the chassis can result in personal injury.
Ensure that the system is disconnected from
its power source and from all
telecommunications links, networks, or
modem lines whenever the chassis cover is
removed. Do not operate the system with the
cover removed.
CAUTION:
To avoid possible damage to the board,
remove power from the computer before beginning
installation. Observe proper anti-static precautions
at all times while handling and installing the board.
To install the Dialogic
®
D/120JCT-LS-EW board,
perform the following steps:
1. Turn off all power to the system and disconnect
the system’s power cords.
2. Remove the computer’s cover.
3. Choose an empty PCI Express expansion slot
and remove the slot’s retaining screw and
access cover plate.
