Default trying to power-up SB1000 - possibly a problem


Sounds simple - is it just a matter of connecting power and pushing the
button on the front? I'm trying to get a SB1000 to power up but it's not
doing anything.

I've got a CPU installed, some RAM, and a framebuffer, plus I have a USB
type-6 keyboard connected (does it matter which USB socket it plugs
into?).

There might be something wrong with the power switch as I can push the
button in quite a long way and nothing happens.

The power supply seems to be doing something as I can hear part of the
circuit running once the power cord is plugged in.

I've got the cover on the system as I noticed the micro-switch. 8-) Still
no joy at the moment...

Craig.

IMHO: If you can't here the fan's then the PSU has a problem.

Are the fans running?

The SB1K/2K take a rather long time to boot. Even the little green light
in the power button only comes on after a minute or so. For a long while
the only indications that something is happening are that the logo
glows and that the fans come one.

In addition, if you've an XVR-100 as primary display, the DVI output
only works once the X server is running.

If the system hasn't come to life after about three minutes, check that
the UPA cards (if any) are seated properly. Make sure you press down on
the center of the card and that it snaps into place completely.

Take care,

If you don't think it's the power supply, then I'd say disconnect the
keyboard and mouse, if applicable.

Then connect to serial port A from another machine via NULL modem cable and
see if you get any output.

If you can get to an ok> prompt then check that the following are set as
follows:

input-device should be keyboard
output-device should be screen
diag-level can be min or max, but min is quicker
diag-switch? should be false unless you like waiting 15-20 minutes to get
screen output
auto-boot? should be false until you have a working OS installed

Then try hooking the keyboard and mouse back up and power cycle the machine.

If you don't get any output at all via the NULL modem connection something
else is likely bad.
