SOME IMPORTANT POINTS TO REMEMBER ABOUT SETUP• When you have more than one work station (display station or a printer) to
set up in a line and they will be connected together, always begin with thework station. that will be connected directly to the system or 5251 Model 2
or 12.

Set up this work
station last.

Set up this work
station first.

•

station second.

Do not attempt to set up more than one display station at a time, eventhough they look alike.

• When you start the setup procedure, read each step slowly and carefully.
Be sure that you understand each step before completing it.
• It is unlikely that you will encounter any problems; but if you do, contact
your planner. If you are the planner, contact your IBM sales or service
