CAUTION:
Should you ever need to open a module and handle the circuit board, use
the wrist strap to connect your wrist to a suitable ground first. Electrostatic
discharge can destroy or severely damage the integrated circuits in the
power supply, processor, and modules.
On-Site Programming Maintenance
You can perform onsite 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 1–1 on page 1–5.
!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.
