Identifying the

Terminal

Type

to

the

Diagnostics

 

 

Note:

This

is

not

the

same

as selecting a console

display.

When

you run diagnostics, you must identify 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.

If

you

specify

an

undefined

terminal

type

from

the

DEFINE

TERMINAL

option

menu,

 

the

menu

prompts

the

user

to

enter

a

valid

terminal

type. The

is

redisplays

until

either

a

valid

type

is

entered

or you

exit the

TERMINAL

option.

 

Resetting

the

Terminal:

 

If you enter 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,

you may

be

unable

to

read

the

screen,

use

the function

keys, or

use

the

Enter

key.

These

difficulties

can be bypassed by pressing Ctrl-C to reset the

terminal. The

screen

display which results from this reset

depends

on

the

mode

in

which

the system

is

being

run:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ÿ Online

Normal

ŸStandalone Mode or Online Service Mode -The terminal typedumb, isthereset to Diagnostic Operating Instruction panel displays, and you are required to go through the DEFINE TERMINAL process again.

Running Standalone Diagnostics

Consider the following when you run Standalone Diagnostics:

ŸThe diagnostic CD must remain in the CD-ROM drive for the entire time that

diagnostics are running.

ŸThe diagnostic CD-ROM cannot be ejected from the CD-ROM drive once the

diagnostics have loaded. The CD can only be ejected after the system has been turned off and then turned on (standalone mode) or after the diagnostics program has terminated (online concurrent mode).

Ÿ The CD-ROM drive from which diagnostics were loaded cannot be tested.

ŸThe SCSI adapter (or circuitry) controlling the CD-ROM drive from which diagnostics were loaded cannot be tested.
