• Use another Ethernet cable. If you’re connecting to a Gigabit Ethernet, make sure you’re using 

an 8-wire Ethernet cable. 

• If the problem continues, contact the vendor.

See 

 for a description of NSA LEDs.

The NSA turns off or reboots by itself. 

Check the

Power Management screen. This is where you configure power settings for the NSA, 

including power saving, UPS, power on/off during power failure and power on/off schedule. The 
NSA may be set to turn off under certain conditions.

A power failure occurred while the NSA is downloading files. 

• If power failure occurs during the active download period, the NSA will verify whether the 

downloaded files were damaged. 

• If a file is corrupted, the NSA will download the file again.
•  If the file is intact but not completely downloaded, the NSA will resume the download task after 

it restarts.

The NAS Starter Utility cannot discover my NSA.

• Close the NAS Starter Utility and reopen it.
• Check your hardware connections and make sure they are set up correctly.
• Only one instance of the NAS Starter Utility can run on your computer. Make sure you close any 

duplicate windows for this application. 

• Wait for the SYS LED to stop blinking before clicking Discover. 
• Confirm that the computer running the NAS Starter Utility has a network connection. See the 

section on the NSA’s LAN connection for related information.

• The computer running the NAS Starter Utility can only discover NSAs in the same subnet. NSAs 

connected to the same switch or router as your NAS Starter Utility computer are usually in the 
same subnet unless the router is doing subnetting or the switch is implementing VLAN.
