Minimum UPS Capacity

 

 

Minimum UPS

When you use an APC Uninterruptible Power Supply (UPS) with a USB connection to the

Capacity

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 On After

Select an option to set whether or not the NSA restarts when the power is restored after a

Power Failure

power failure.

 

Note: This feature is not supported on NSA310.

 

 

Keep Former

Select this option to have the NSA automatically restart only if it was operating when the

Status

power failed. The NSA remains off if it was already off when the power failed.

 

 

Always

Select this option to keep the NSA operating as much of the time as possible. The NSA

Power On

restarts automatically even if it was turned off when the power failed.
