The NAS Starter Utility discovered my NSA but the status is always unreachable, even though
I can access it.
You may need to add the NAS Starter Utility to your software firewall’s allow list or lower your
software firewall or anti-virus scanner’s security level. Alternatively you may have to configure your
software firewall or other security software to allow UDP port 50127 traffic from the NSA. If there is
a hardware firewall between you and the NSA, configure it to allow UDP port 50127 traffic from the
NSA.
I was able to access the NSA on a previous attempt but I cannot access the NSA anymore.
If you enable jumbo frames on the NSA in a network that does not support them, you will lose
access to the NSA. If this occurs, you will have to restore the factory default configuration. The
reset process does NOT affect the volume settings, nor data stored on the NSA. Press the RESET
button until you hear two beeps. After the second beep, continue pressing the button for five more
seconds, then release it. You will hear three quick beeps after you release the button.
I have at least two NSAs in my network, how do I identify which one I want to configure in
the NAS Starter Utility screens.
If you have several NSAs connected to your computer/network, give each a unique name. You may
have to disconnect all but one and use the NAS Starter Utility to rename it. Then connect another
NSA and rename it and continue to connect and rename the NSAs one-by-one until they are all
connected and each has a unique name.
Alternatively, if you have a DHCP server on your network and you can access it’s list of assigned IP
addresses, you could see which IP address belongs to which NSA. You can check the MAC address
of your NSA by checking the attached sticker in the device housing.
20.4 NSA Login and Access
I forgot the server name of the NSA.
The default server name is ‘nsa’ followed by the number of your model (‘nsa320’ for example).
Use the NAS Starter Utility to discover your NSA. If you have admin privileges, you can directly
change the IP address of the NSA using the NAS Starter Utility.
If the server name has changed and you don’t have the NAS Starter Utility, see Section 1.1.4 on
page 19 to use the RESET button to return to the default setting.
