DA-15

V89 Cascade module BNC

V93A Host module: V.32bis modem RJ-11

M03* Memory module: Expandable up to 16MB N/A

* - The M03 memory module occupies one module slot thereby reducing the maximum number

of host or I/O modules the can be installed by one

IMPORTANT: The first module slot (Module 1) of a M8 or M16 with a

LCD display must be occupied by a host module.

You will need a straight-slot screwdriver to perform the installation.

1. IMPORTANT: Remove power from the unit by depressing the power

switch on the front of the unit to OFF and also remove the power cord from

the socket.

2. Determine which module slot the module will install into. Modules are

typically installed in sequence from left to right (facing rear of unit). The

module slots are labeled on the top panel as "1", "2", ..., "16". If you need to

upgrade the memory on the M03 memory module, please refer to Appendix

B.4 before installing the module into the base unit.

3. Remove the flat aluminum plate covering the slot into which the new module

will be installed by loosening the 2 straight slot screws and then removing

the plate from the rear panel. Save the aluminum plate in the event you have

to remove the module in the future.

4. Install the new module by sliding the horizontal card edges along the

grooves inside the module slot. Each module has a card-edge connector that

fits into a receptacle inside the base unit. Apply a moderate amount of

pressure to the connector board of the module until you feel the card edge

connector slip into the receptacle inside. You will not be able to mount the

back plate of the module to the chassis if the module is not installed all the

way.

5. Mount the back plate of the module to the M Series chassis by tightening the

2 straight slot screws on the back plate.
