Connecting the DCP Cord Attach the DCP type D8W telephone cord as follows:

1.Insert either end of the telephone cord into the connector on the rear panel of the Data Module labeled LINE.

2.Insert the other end of the telephone cord into the PBX wall jack.

3.If you are using the with-phone option of the 7400B Data Module (voice and data), install the second D8W telephone cord as follows:

a.Insert one end of the second D8W cord into the jack on your 7400-series DCP voice terminal.

b.Insert the other end of the second D8W cord into the jack on the rear panel of the Data Module labeled PHONE.

Note: An internal DIP-switch must be set correctly for this option to work (see "Setting the Hardware Option Switches" in this chapter). Also, if your voice terminal has data capabilities, the data features of the voice terminal are not supported while it is connected to the 7400B Data Module.

Connecting the Power

Connect the separate power supply unit to the 7400B Data Module as

supply

follows:

 

 

1. Insert the output connector of the power supply into the connector

 

on the rear panel of the Data Module labeled “POWER.”

 

Caution: Be sure that the side of the power supply cable

 

 

connector labeled “TOP” is facing upward before

 

 

inserting the connector.

 

2. Insert the AC connector of the power supply unit into an

 

appropriate AC outlet.

 

Note:

Since the 7400B Data Module does not have a power

 

 

on/off switch, the unit will power on as soon as the

 

 

power supply is connected to an active AC line.

 

Caution:

Make certain that the AC outlet to which you connect the

 

 

power supply is unswitched (for example, not controlled

 

 

by a wall switch or light dimmer).
