Identifying the Terminal Type to the Diagnostics Programs
Note: This is a different function than selecting a console display.
When you run diagnostics, the diagnostics must know what type of terminal you are
using. If the terminal type is not known when the FUNCTION SELECTION menu is
displayed, the diagnostics do not allow you to continue until a terminal is selected
from the DEFINE TERMINAL option menu. Select lft for adapter-attached displays.
Undefined Terminal Types
If an undefined terminal type from the DEFINE TERMINAL option menu is entered,
the menu prompts the user to enter a valid terminal type, and the menu is
re-displayed until either a valid type is entered or the user exits the DEFINE
TERMINAL option.
Resetting the Terminal
If the user enters a terminal type that is valid (according to the DEFINE TERMINAL
option menu) but is not the correct type for the ASCII terminal being used, difficulty
may be encountered in reading the screen, using the function keys or the Enter key.
These difficulties can be bypassed by pressing Ctrl-C to reset the terminal. The
screen display which results from this resetting action varies with the mode which the
system is being run:
Ÿ
Online Normal or Maintenance Mode - The command prompt appears.
Ÿ
Stand-alone Mode or Online Service Mode -The terminal type is reset to "dumb",
the Diagnostic Operating Instruction panel is displayed, and the user is required
to go through the DEFINE TERMINAL process again.
Running Stand-alone Diagnostics
Consider the following when you run Stand-alone Diagnostics:
Ÿ
The diagnostic disc must remain in the CD-ROM drive for the entire time that
diagnostics are executing.
Ÿ
The diagnostic CD-ROM disc cannot be ejected from the CD-ROM drive once
the diagnostic programs have loaded. The disc can only be ejected after the
system has been powered-Off and then powered-On (Stand-alone mode) or after
the diagnostics program has terminated (Online concurrent mode). The disc must
be ejected before the system attempting to load the diagnostic programs again.
Ÿ
The CD-ROM drive from which diagnostics were loaded cannot be tested.
Ÿ
The SCSI adapter (or circuitry) controlling the CD-ROM drive from which
diagnostics were loaded cannot be tested.
