WARNING! Powering down the system processor interrupts traffic and
causes loss of system logs and diagnostic data. To preserve this diagnostic data
it is recommended that the vincident and/or save log commands be
used prior to powering down the system.
It is recommended to reboot the system rather than powering down then up.
Using a syslog server also ensures logs are stored prior to any reboot or power
down. See Displaying and Setting System Log (Syslog) Options on page 71.
