1. 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 Dialogic® Station Interface Box (“SIB”) according to the following steps:

1.Prepare a static-safeguarded work area.

2.Carefully remove the SIB from the shipping carton and anti-static packaging. Handle the SIB by the edges and avoid touching the components.

3.Lay the SIB on the static-dissipative work surface.

Note: Place the SIB in static-shielding bags when carrying from station to station.

CAUTION: Do not remove the SIB from the anti-static packaging until you are ready to install it. Observe proper anti-static precautions at all times.

2. Upgrading the Station Interface Box

The Dialogic® Station Interface Box (“SIB”) is a single unit that supports 48 stations in the base model configuration. However, the SIB is a modular unit that is designed to accommodate 72, 96, and 120 stations.

Configuring the Station Density

To support 72 stations, install one SI/240 board at the location designated STA 49-72on the SIB rear panel. To support 96 stations, install two SI/240 boards; one daughter board at the location designated STA 49-72and the other daughter board at the location designated STA 73-96on the SIB rear panel. To support 120 stations, install three SI/240 boards; the first daughter board at the location designated STA 49-72, the second daughter board at the location designated STA 73-96, and the last daughter board at the location designated

STA 97-120on the SIB rear panel.

SIB Station Density Table

Use the following table to determine the correct location for installing the SI/240 boards in your SIB.

Caution! The SIB will fail to function properly unless you install the SI/240 boards in the correct locations on the SIB base board. The P3, P4, and P5 connector designations are silk screened on the base board to help you correctly install the SI/240 boards. (For reference, base board connector P3 is located nearest the power supply fan.)

3. Warnings

Warning! These procedures assume familiarity with the general terminology associated with electronic equipment and with the safety practices and regulatory compliance required for using and modifying electronic equipment.

Warning! These procedures should be performed only by qualified technical personnel. Unplug the SIB power cord before performing the procedures described here. Failure to disconnect the power before you open the chassis can result in personal injury or equipment damage.

Warning! The power supply in the Dialogic® Station Interface Box contains no user-serviceable parts. Refer servicing only to qualified technical personnel.

Warning! 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.

Advertissement! Assurez vous que le système soit débranché de son alimentation ainsi que de toutes les liaisons de télécommunication, des réseaux, et des lignes de modem avant d’enlever le capot. Ne pas utiliser le système quand le capot est enlevé.

Warnug! Das System darf weder an eine Stromquelle angeschlossen sein noch eine Verbindung mit einer Telekommunikationseinrichtung, einem Netzwerk oder einer Modem-Leitung haben, wenn die Gehäuseabdeckung entfernt wird. Nehmen Sie das System nicht ohne die Abdeckung in Betrieb.

Avvertenza! Prima di rimuovere il coperchio del telaio, assicurarsi che il sistema sia scollegato dall’alimentazione, da tutti I collegamenti di comunicazione, reti o linee di modem. Non avviare il sistema senza aver prima messo a posto il coperchio.

Advertencias! Asegúrese de que cada vez que se quite la cubierta del chasis, el sistema haya sido desconectado de la red de alimentación y de todos lo enlaces de telecomunicaciones, de red y de líneas de módem. No ponga en funcionamiento el sistema mientras la cubierta esté quitada.
