Chapter 8. Using the System Verification Procedure
The system verification procedure is used to check the system for correct operation.
When you are analyzing a hardware problem, see Chapter 9 on page 9-1.

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, be sure communications with the other system unit is 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 ter-
minal attached to the S1 port.
Before starting this procedure, you should stop all programs and the operating
system.
This procedure runs the Online Diagnostics in Service mode or Standalone Diag-
nostics. If the Online Diagnostics are installed, they should be run. See the oper-
ator 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 6 on page 6-1.
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.
ISA adapters cannot be detected by the system. The ISA adapter Configuration
Service Aid allows the identification and configuration of ISA adapters when
running standalone diagnostics.
Go to Step 2.
