Power Management

Turn off hard 
disk(s)

Enter the number of minutes the NSA will sit idle before spinning the hard disks down to 
sleep. The default power-off time is 15 minutes.

Minimum UPS Capacity

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 On After 
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.
