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.
