8-6 Cabling, installing, and configuring the peripheral devices

Installing the primary administration terminal

Standard 1.0 Option 11 EC Installation and Maintenance Guide November 1999

Installing an A/B

switchbox

The installation requires an A/B switchbox for remote

support. Place the switch into the “A” position to connect the

EC 11 to the local administration terminal. Place the switch

into the “B” position to connect the EC 11 to a modem which

can be dialed up by a remote maintenance terminal and

remote modem (usually at Nortel).

To install the A/B switchbox, follow these steps.

5 Plug the terminal’s AC 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.

Step Action

1 Place the A/B switchbox in a suitable location within

4.5 m (15 ft.) of the EC 11.

Although the switchbox may vary from the one

shown on the next page, the installation is the same.

See the instructions provided with the switchbox for

specific details.

2 Set the switch on the front of the A/B switchbox to

the A position.

a. Label the A switch position “Local.”

b. Label the B switch position “Remote.”

3 If there is an administration terminal already

connected directly to the EC 11, disconnect the

cable from the EC 11. Leave the cable attached to

the administration terminal.

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

(NTND91AA/AB) to the connector on the EC 11

labeled “Console.”

5 Connect the other end of the straight-through cable

to the common connector (usually marked C) on the

A/B switchbox.

6 If you have disconnected the administration terminal

in step 3, connect it now through its cable and null

modem adapter to the connector marked A on the

A/B switchbox.

If you have not yet installed the administration

terminal, see the “Installing the primary

administration terminal to an A/B switchbox”

procedure on the following page.
