DESCRIPTION
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.

itself every 60 seconds.

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
11.6 on page 240). 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.
This displays the name which helps you find the NSA on the network.
