15.3.1.1 Using the Reset Button
When you use the following reset procedure, the system name and admin password are
returned to the factory defaults.
You may need to close and re-open the NDU to discover the NSA. This is because the NSA
automatically re-acquires IP address information, so its IP address may change since. If no IP
address information is assigned, the NSA uses Auto-IP to assign itself an IP address and
subnet mask. For example, you could connect the NSA directly to your computer. If the
computer is also set to get an IP address automatically, the computer and the NSA will choose
addresses for themselves and be able to communicate.
