I have a couple of Suns that underwent reboot and they didn't come back up. At least I can't ping them or log into them. They are located across town, so they are not readily accessible. Luckily, unlike the other servers in the rack, they have video cards, but they haven't been used in a long time. We normally access then through ssh. Anyway I connected a monitor, but saw nothing as it was coming up. My other option to try and see if anything is happening is a dumb terminal to a serial port.
