11. If you loaded the diagnostics from the disk, press the F3 key (from a defined terminal) or
press 99 (for an undefined terminal) to shutdown the diagnostics before turning off the
system unit.
Note: Pressing the F3 key (from a defined terminal) produces a "Confirm Exit" popup menu
which offers two options: continuing with the shutdown by pressing F3; or returning
to diagnostics by pressing Enter.
For undefined terminals, pressing 99 produces a full screen menu which offers two
options: continuing with the shutdown by pressing 99 and then Enter; or returning to
diagnostics by pressing Enter.

system unit after the shutdown is complete.

System Exerciser

The System Exerciser tests and exercises devices in an overlap mode and can only be run
from disk in standalone or maintenance mode.
Starting the System Exerciser
When the System Exerciser is selected from the FUNCTION SELECTION menu, another
menu displays all devices to be tested. Pressing the Enter key starts tests for all of the
devices.
The time required to test all of the devices depends on the number of devices to be tested
and can range from several minutes to approximately one hour for a fully loaded system.
Because some devices require less time to test than others, the number of times a device is
tested under the System Exerciser may be one or more.
Note: If the system contains tape devices, CD-ROM, or diskette drives, you are asked
whether you want to use media in the devices when you are testing.
Display Screens
If the console is a graphics display, normal test patterns are displayed during the tests. After
the graphics adapter test is finished, the standby screen is displayed.
If the console is an async terminal, the standby screen is displayed during testing. The
time-of-day is displayed at the top of the screen and is updated approximately every minute.
After all devices have been tested at least once, a results screen is displayed until either the
Enter key is pressed to restart the System Exerciser or the Exerciser is stopped. If no errors
were detected, the results screen displays the No trouble found message; if errors
have been detected, the results screen displays a list of devices with corresponding errors.
Stopping the System Exerciser
Although the System Exerciser can be stopped at any time, it is best to stop it while the
results screen is displayed. Stopping the Exerciser at other times can cause the loss of test
information.
When the System Exerciser is stopped, the screen displays all tested devices with errors
flagged. Selecting a device that has an error flag provides details such as SRN, location
code, number of times the device was tested, and the number of times an error was
detected.
Using the System Exerciser to Check Out Repairs and Intermittent Problems
The System Exerciser can be used to check out the system following repairs and to identify
intermittent problems.
