Chapter 7. Using the System Verification Procedure
Use the system verification procedure to check the system for correct operation.
If you are analyzing a hardware problem, see Chapter 8, “Hardware Problem
Determination” on page 155.
Step 1. Considerations before Running This Procedure
Notes:
1. If this system unit is directly attached to another system unit or attached to a
network, make sure that communications with the other system unit are stopped.
2. This procedure requires use of all of the system resources. No other activity can
be running on the system while you are doing this procedure.
Read the following before using this procedure:
This procedure requires a display connected to the video port or an ASCII
terminal attached to the S1 port.
Before starting this procedure, stop all programs and the operating system.
This procedure runs the Online Diagnostics in Service mode or Standalone
Diagnostics. If the Online Diagnostics are installed, they should be run. See the
operator manual for your type of ASCII terminal to find the key sequences you
need in order to respond to the diagnostics.
For additional information about diagnostics, see Chapter 5, “Using the Online
and Standalone Diagnostics” on page 95.
If a console display is not selected, the diagnostics stop. The instructions for
selecting a console display are displayed on all of the graphic displays and any
terminal attached to the S1 port. Follow the displayed instructions to select a
console display.
Go to Step 2.
