I was fortunate enough to recently get a brand new Sunfire v890 server. Oh how excited I was to see what this baby could do. I had to wait, unfortunately, until we could make space in our server room for it. Then the day finally came where I could power it on for the first time.
As you may, or may not, know Sun servers don't come with video cards out of the box and we had scheduled a rep to come down and install it for us. I am more than capable of this feat, but had not intention of taking the responsibility for it or possibly losing a warranty becuase it wasn't installed by a certified Sun installer. Nevertheless I wanted to see what it could do so I unplugged a laptop we were using as a serial terminal in an older v880 that we never put a video card in. That's where I learned the hard lesson.
NEVER UNPLUG A SERIAL TERMINAL FROM A RUNNING SUN SERVER
What could go wrong, I'm only unplugging a serial cable, I thought to myself. That's akin to disconnecting a vga cable right? WRONG. This apparently will make the server go down into single user mode. You won't be able to ping, telnet or do anything else with the server until it is plugged back in. Fortunately, this all occured at the end of the day and no one really seemed to notice.
