Refer to the Release Guide and the online Release Update for your Dialogic system software release to verify that the DISI is 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 DISI board contains safety warnings and national requirements for proper operation of telecommunications equipment.

WARNING! This analog station interface product is designed to be used only within the walls of a single stand-alone building or structure (i.e., on-premise). It is not designed to sustain electrical overstress from external sources and factors such as severe weather conditions. Severe electrical overstress caused by misuse of this interface product with cables extending outside of the walls of a single stand- alone building or structure could cause property damage and/or personal injury and/or death. Such misuse voids the warranty for this interface product.

2. Before You Begin

Protecting the Board from Damage

CAUTION: All computer boards are sensitive to electrostatic discharge. 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

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, leave SW100 set to the 0 position (the factory default setting) on all Dialogic telecom boards. This setting causes the system software to assign instance numbers geographically, based on the bus and slot numbers. Note that 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.

You can read the ID numbers assigned to the boards in the Configuration Manager tool after you start the system.

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 in your System Software documentation for further information about the board ID numbers.

4. Choosing a Slot

The DISI 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
