• Make sure the Ethernet cable is connected properly to the NAS and connected to another
(Ethernet) device. Make sure the other device is turned on. If it’s connected directly to a
computer, make sure that the computer network card is working (ping 127.0.0.1 on the
computer).
• 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 Table 1 on page 15 for a description of NAS LEDs.
The NAS turns off or reboots by itself.
Check the Power Management screen. This is where you configure power settings for the NAS,
including power saving, UPS, power on/off during power failure and power on/off schedule. The
NAS may be set to turn off under certain conditions.
A power failure occurred while the NAS was downloading files.

it restarts.

The NAS Starter Utility cannot discover my NAS.
• 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 NAS’s LAN connection for related information.

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.
