Installing the multiple administration terminals

Installing MATs

Each EC11 installation includes a primary administration

terminal. In addition, optional multiple administration

terminals (MATs) can be used for non-critical administration

functions such as adding customers or configuring customer

options. You may install no more than one MAT per node.

Note: You must have the multiple administration terminals

feature installed.

To install a MAT, follow these steps.

The original installer or supplier of the installation software

should have configured a port for each MAT.

Step Action

1 Place the multiple administration terminal in a

suitable location.

The terminal should be installed within 15 m (50 ft.)

of the EC 11 system. If the distance is greater than

15 m (50 ft.), asynchronous limited distance

modems must be used.

2 Connect the keyboard and power cord to the

terminal.

3 Connect one end of a straight-through RS-232 cable

(NTND91AA/AB) to a null modem adapter

(NTND93AA). Connect the other end of the adapter

to the serial COMM or COMM1 connector on the

terminal. Use a gender changer as necessary

(A0351509).

4 Connect the free end of the cable to an RS-232 port

on the EC 11 that has already been configured for a

MAT. This could be a port on a utility card in either

node (on one of the 4-port fanout cable connectors),

or a port on the node 2 Enhanced MMP40 or

MMP40 card.

5 Plug the terminal cord into an AC receptacle, and

power on the terminal.

6 Configure the terminal as described in “Configuring

the administration terminal” on page 8-40.
