Installing the RSM Breakout Assembly (NTAK18AA/BA)

The RSM Breakout Assembly is a small circuit board that sits in the cavity

beneath the three Meridian Mail cards and is connected to connector J10, the

rightmost of the 25-pair connectors that run the length of the Meridian 1 cab-

inet. An MDF cable is attached to this assembly and allows the customer to

connect other RS-232 devices to Meridian Mail, most notably for the Merid-

ian Mail Hospitality Voice Services system and for networking.

The RSM Breakout Assembly is available in two varieties: NTAK18BA

should be installed in areas requiring enhanced protection from electromag-

netic interference, NTAK18AA can be used in all other situations. Apart from

this difference, the two cards are installed in exactly the same way and func-

tion identically.

If you are installing a new Meridian Mail system, install the RSM Breakout

Assembly before any of the other cards.

If you are adding an RSM Breakout Assembly to an existing system:

a. Courtesy down Meridian Mail and turn it off. (Refer to page 4-5.)

b. Grasping the top three lock latches with one hand and the bottom

three latches with the other, unlock all three cards simultaneously

and pull the assembly out slowly until the 68k Card comes un-

plugged from the back of the cabinet. There is no need to remove

it completely.

2 Remove the cable restraining bar.

3 Plug the end of the MDF cable equipped with a cubic ferrite ring into the

RSM Breakout Assembly.

4 Move the small switch on the RSM Breakout Assembly to the “Normal”

position as indicated on the Assembly.

DANGER

Shock hazard

Before installing the RSM Breakout Assembly, ensure

that the 68k Card is not plugged into the back of the

Meridian 1 cabinet. Turning off Meridian Mail is not

enough.
