The preferred method of rebooting an SGI workstation is to select System/Restart System from the "toolchest" menu. That will prompt you for the root password, which on the public workstations can be found out by typing tellme root at the athena% prompt. Instead of using the menu, you can also type: su enter the root password when prompted, and then type: reboot If you can't do either of those, press the power button (the round button next to the red/green power light). On SGIs, this will do an orderly shutdown and turn off the machine. Once the machine shuts off, wait 30 seconds and press it again to turn it back on and boot. If all those methods fail, please contact the Hardware Hotline by calling x3-1410 or sending mail to "hotline@mit.edu".
