On-Site Programming Maintenance

On-Site Programming Maintenance
You can perform on-site maintenance with an MLX-20L console or a PC with
SPM software. This book provides maintenance instructions from the console. If
you are using a PC, refer to System Programming and Maintenance (SPM) for
details. If you use the UNIX System, see the documentation for Integrated
Solution Ill (IS III).
Setting Up the MLX-20L Console
To connect an MLX-20L console to the control unit, follow the steps below.
Refer to Figure
Plug one end of a D8W-87 cord into one of the first five jacks on the

leftmost 008 MLX module or 408 GS/LS-MLX module.
The first MLX jack is the default. If it is already being used for the
attendant console, choose another jack. If one of the jacks is already
being used for system programming or maintenance, use that jack. Only
one jack at a time can be used for system programming or maintenance.
Plug the other end of the D8W-87 cord into the LINE jack on the

underside of the MLX-20L console.
MLX-20L Failure
If the MLX-20L console does not work, follow the steps below.
Replace the MLX-20L console with one that is known to be working

(if available).
If the failure persists, or if a working MLX-20L console is not

available, connect the original MLX-20L console directly into the
appropriate MLX jack on the control unit using a cord that is known
to be working.
