Minimum UPS
Capacity
When you use an APC Uninterruptible Power Supply (UPS) with a USB
connection to the NSA, the NSA shuts itself down if the APC UPS’s
battery charge gets down to the percentage you specify in this field. This
allows the NSA to shut down properly and avoid data loss caused by a
power failure when the UPS stops supplying power.
A setting around 50% is recommended. A setting close to 100% is not
recommended since it would cause the NSA to shut down whenever the
UPS is charging. A setting close to 0 is also not recommended since the
UPS would not have enough power to allow the NSA to shutdown
properly.

Power Failure
Select an option to set whether or not the NSA restarts when the power
is restored after a power failure.
Keep Former
Status
Select this option to have the NSA automatically restart only if it was
operating when the power failed. The NSA remains off if it was already
off when the power failed.
Always Power
On
Select this option to keep the NSA operating as much of the time as
possible. The NSA restarts automatically even if it was turned off when
the power failed.
Always Power
Off
Select this option to keep the NSA from automatically restarting when
the power is restored after a power failure. This is a computer’s
“traditional” behavior. Select this if you have other servers such as a
domain controller or DNS server that you want to start or check after a
power failure before the NSA turns on.
