Re: Workstation won't start after enabling POST

Hello all,

to perform the power on self-test on my Blade 1000, I entered at the
system prompt
setenv diag-switch? true
setenv diag-level = max
and rebooted the system.

The fans started, the LED in the cdrom flashed, but after that nothing
happened anymore.
My monitor did not get any signal and even the LEDs on the USB
keyboard didn't flash.

The "Sun Blade 1000/2000 Service Manual".says that it might take some
time to perform the POST but even after more than 1h nothing has
changed.

The manual also says that I should have set up an TIP connection which
I surely would have done if I had read the manual before :(

Has anybody an idea what I can do to use the system again?

Set up the TIP connection now. Connect to TTYA. Your
diag-switch changed the:

output-device=screen
input-device=keyboard

to

output-device=ttya
input-device=ttya

so until you have a serial terminal -- or a TIP session masquerading as
one -- connected to the system, it will ignore the keyboard and monitor.

Once you are in there with the TIP session, try:

set-defaults

which should restore things to a normal set of defaults. But it may
also lose a custom "boot-device" setting pointing to the specific drive
in your internal disk cage (assuming that you have an installed system
to save). If you simply want to get in and install, you can just use
the "boot-cdrom" to get started with the installation.

Powering off an on, pressing Stop and Stop-N, deconnecting monitor and
keyboard and trying to connect via serial interface - nothing gave me
the system prompt.

It is not looking at the keyboard, so these will do nothing but
possibly corrupt the disk if you had a bootable system installed. The
TIP session connected to ttya will produce output -- eventually. It
should not take an hour, but it may take some ten minutes depending on
the speed of the CPU modules present and the amount of RAM in the
system.

Good Luck,
DoN.
