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.
