7.3.2 What to Do

Ensure that the front panel keyswitch is in the Standby position.

You can initialize POST one of two ways:

By setting the diag-switch? to true and the diag-level to max or min,

followed by power cycling the system unit

By simultaneously pressing the keyboard Stop and D keys while power is applied

to the system unit

To set the diag-switch? to true and power cycle the system unit:

1. When the ok prompt is displayed, type the following command:

ok setenv diag-switch? true

2. At the Type-5 keyboard, power cycle the system by simultaneously pressing

the Shift key and the Power-on key After a few seconds press the Power-on

key again, or press the Power button on the system once.

Note - The keyswitch must be set to the Power-On/Off position.

The system runs the POST diagnostics. POST displays status and error messages on

the system console. For more information, see the “Results” section below.

Upon successful completion of POST, the system runs OBDiag. For more information

about OBDiag, see Section 7.5 “About OpenBoot Diagnostics (OBDiag)” on page 192

and Section 7.6 “How to Use OpenBoot Diagnostics (OBDiag)” on page 195.

7.3.3 Results

While POST is running, you can observe its progress and any error indications in the

following locations:

System console or through a tip connection

Front panel fault LEDs

Keyboard LEDs (if a keyboard is present)
