2-2 CHAPTER 2: INSTALLATION AND OPERATION

Installing The Module

Before installing the module, read the Safety Information at the front of this guide.

An AccessBuilder 7000 module consists of two parts; a front card and a back card that both connect to the chassis’ backplane. It is recommended that you install the module’s rear card into the chassis first.

The installation of the Triple Modem Module into the AccessBuilder

7000 chassis takes place in three distinct operations:

■Installing the front card.

■Installing the rear card.

■Connecting cables to the DTE and Line ports. See “Connecting the Cables” on page 2-5for more information about connecting to the ports.

Modules within the AccessBuilder 7000 system are designed to be hot swapable. It is not necessary to turn off the AccessBuilder 7000’s power supply unit to install the Triple Modem Module. The Triple Modem Module can be inserted any slot in the AccessBuilder 7000 chassis.

No connecting cables are supplied with the Triple Modem Module as standard. For each of the three modems you need a PSTN line cable and/or a 2/4-wire private line cable. You also need a cable to connect your computer or DTE equipment to the DTE interface on the modem. The male DTE connector conforms to the electrical characteristics of V.24 as described in Appendix A.

CAUTION: At all times, take care not to touch any of the connectors or components on the cards to avoid damage by static electricity. Handle the cards by the handles or by their edges. Use an anti-static wrist strap during installation if you have one available.
