Subject:    -7- Should I shut off my Iris at night?

  (Home users often ask this.) No, you should not. The hardware is
  designed for continuous use, and IRIX schedules cleanup tasks for the
  early morning. (See the cron(1M) and crontab(1) manpages and the
  files in /usr/spool/cron.) Disks, tapes, CD-ROMs etc. consume little
  power when idle and should NEVER be turned off or on (or connected or
  disconnected) when the system is running.

  However, turning off your *monitor* will save power and prolong its
  life.
