System Resources
CPU Usage This displays NSA CPU usage by all current processes since the last
update. If too many users are using the NSA then the NSA may appear
sluggish.
CPU Temperature This displays the current temperature of the NSA CPU. If the temperature
is not within range (about 0
O
to 85
O
C) the NSA may malfunction. If the
NSA overheats for example, turn it off and let it cool down. Make sure the
fans are working and it is in a well ventilated place.
Memory Usage This number shows how much of the NSA's total memory is being used.
Open Sessions This shows the current number of active sessions. It is useful when you
want to restart or shutdown the NSA so you can tell if there are users
currently connected to the NSA. You should then contact each user to
make sure that they disconnect from the NSA before you restart or shut it
down. Click the view details link to go to the System Status > Active
Sessions screen.
UPS This field displays whether an Uninteruptable Power Supply (UPS) is
being used. A UPS is advisable to protect sensitive data stored on the
NSA in the event of a power outage.
A battery meter displays what percentage Uninteruptable
Power Supply
(UPS) battery power remains when an APC UPS is connected to an NSA
USB port and is turned on. Power from the UPS is used when power from
the mains is down and while the UPS has battery power.
Power from the mains is used when the mains power returns; the APC
UPS battery is recharged then too. This field displays N/A when no UPS is
connected to the NSA or it is turned off.
System Status
System Name This displays the name which helps you find the NSA on the network. Click
the update link to go to the Network > TCP/IP screen. Click the Modify
button after the Server Name label in that screen to go to the Network >
Windows/CIFS in which you can change the Server Name.
You can enter up to 15 alphanumeric characters with minus signs allowed
but not as the last character. The name must begin with an alphabetic
character (a-z) and is NOT case sensitive.

link to go to the Maintenance > Firmware Upgrade screen from which
you can upload new firmware.
System Uptime This is the total time the NSA has been on since your last power-up.
System Time This displays the date (month/date/year) and time (hours/minutes/
seconds). Click the update link to go to the Maintenance > Date/Time
screen from which you can change the system time.
