Not if there's a frame buffer installed. And that sound like you're in the host serial port, not the management port. Which do you want to be connected to?

I had it working, briefly, but it stopped again. I think it had booted from the CD, and was pouring out messages about a buffer overflow plus a language-selection menu (repeatedly) as fast as 9600 bps would allow. Then I removed the CD and rebooted and now nothing. With a Sun Fire, shouldn't I be able to turn the front-panel switch to "Normal" and press the power button? I did that, and I'm getting nothing on the serial interface. I should be getting POST messages at least.

I have a SunFire V490 at work. I also have a HP ProLiant server in the
same
rack, which is running Ubuntu Server 10.04. I've got the weird cyan serial cable plugged in to the lone serial port on the ProLiant and the other end plugged into the V490 port ("SERIAL"). I've got minicom running on the
Linux
box configured for 9600, 8N1 on /dev/ttyS0. minicom's status line reports "OFFLINE", and I get no response to any keyboard input.
What's wrong? I can freely power off/on the SunFire and anything else I
want
to do with it. I have the keys for the front panel, too. Do I have to
switch
it to diagnostics mode or something? We had it working before, and it was quite easy.
Help!

No frame buffer is present. I just want to manage the machine via serial port for now. You can't use the management port until you've installed the OS and configured it, is my understanding.
