Keyboard LEDs

Four LEDs on the Sun Type-5 keyboard are used to indicate the progress and results

of POST diagnostics. These LEDs are on the Caps Lock, Compose, Scroll Lock, and

Num Lock keys, as shown below.

To indicate the beginning of POST diagnostics, the four LEDs briefly light all at once.

The monitor screen remains blank, and the Caps Lock LED blinks for the duration of

the testing.

If the system passes all POST diagnostic tests, all four LEDs light again and then go

off. Once the system banner appears on the monitor screen, the keyboard LEDs

assume their normal functions and should no longer be interpreted as diagnostic

error indicators.

If the system fails any test, one or more LEDs will light to form an error code that

indicates the nature of the problem.

Note – The LED error code may be lit continuously, or for just a few seconds, so it

is important to observe the LEDs closely while POST is running.
