CPU Temperature
This displays the current temperature near the NSA’s CPU. The NSA 
generates an emergency log if the temperature goes out of the normal 
operating range. If the temperature goes even higher, the NSA shuts 
down automatically to avoid damage from overheating. If the NSA 
overheats, make sure the fans are working and it is in a well ventilated 
place. 
Click the Refresh icon to update this display. It also automatically updates 
itself every 60 seconds.

UPS Status
When you use an APC Uninterruptible Power Supply (UPS) with a USB 
connection to the NSA, this field displays the remaining charge for the 
UPS’s battery. A UPS is advisable to protect sensitive data stored on the 
NSA in the event of a power outage. 
The NSA uses power from the UPS when the normal power source is 
down and while the UPS still has battery power. 
The NSA shuts itself down if the UPS’s battery charge gets down to the 
percentage you specify in the Power Management screen (see 
). This allows the NSA to shut down properly and avoid 
data loss caused by a power failure when the UPS stops supplying power.
The NSA uses power from the normal power source again when its power 
returns. The APC UPS battery is recharged then too.
