Troubleshooting terminal problems

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Determining a problem

with terminal cables

and setup

To determine if the problem with the terminal involves the

terminal cables and setup, follow these steps.

4 If the hexadecimal display increments past .3 but the screen

remains blank, there may be a problem with the Enhanced

MMP40 (or MMP40) card. Replace the card and return to

step 1.

5 If none of these steps succeeds in solving the problem, contact

your Nortel Networks support organization.

Step Action

1 Make sure the terminal is installed and configured as described

in Appendix A, “Terminal configuration.”

2 If the terminal was working previously, enter terminal setup and

perform “Clear communications,” then reset the terminal.

3 If the terminal was working previously and the printer is printing

SEER reports, enter terminal setup and verify that the terminal

is not in controller print mode. The print mode should be

Normal Print Mode for all terminals, except the HP700/32. For

the HP700/32, enter terminal setup and set the user Aux Mode

to OFF.

4 Verify that the “Hold screen” key is not on. If the terminal

indicates “Hold” (status area at bottom of screen, or LED on

keyboard), press F1 to release the hold.

5 Check all the cable connections to the terminal.

6 Replace the cables and adapters one at a time.

7 Check the printer setup and status.

Refer to Chapter 10, “Installing, cabling, and configuring

peripheral devices” for the correct printer setup.

8 Clear any printer faults (out of paper, paper jam) and put the

printer online.

9 To make sure the terminal is functional, enter setup mode.

10 Change the terminal setup to enable LOCAL ECHO, and, with

the printer attached, enter text from the terminal keyboard.

Result:

The text you enter from the keyboard should echo on

the terminal screen.
