Automatic power on restart

Caution
40
As with all sophisticated electronic equipment, unstable power during a
restart can induce problems. Hewlett-Packard recommends automatic
power on restart only when the power to the disk array is conditioned to
ensure stability (for example, using a UPS). If your site does not have a
UPS, HP recommends configuring the disk array for manual restart by
keeping the ENABLE/DISABLE switch in the DISABLE position and using
the manual restart procedure when power has been restored and verified.
Your disk array will automatically restart and return to service when power
is restored. To enable this feature, place the ENABLE/DISABLE switch in
the ENABLE position and the PWR ON/OFF switch in the PWR ON
position (Figure 3 on page
