To avoid damaging the file system and causing any corruption, do not turn the device off with the power button without first shutting down the system.
Use this command to cleanly and properly shut the system down:

   shutdown −-h now

Auto booting of the N3xx when power is applied can be configured by enabling the flag on the device's EEPROM with the following command:

   eeprom-set-flags 0x1

The default user is 

root

 and the password is empty (no password).

It is recommended to update the 

root

 password, which can be done with the command 

passwd

:

Example Output:

   root@ni-n3xx-serial:~# passwd
   Changing password for root
   New password: 
   Re-enter new password: 
   passwd: password changed.

Technical support for USRP hardware is available through email only. If the product arrived in a non−functional state or you require technical assistance,
please contact 

[email protected]

. Please allow 24 to 48 hours for response by email, depending on holidays and weekends, although we are often

able to reply more quickly than that.

We also recommend that you subscribe to the community mailing lists. The mailing lists have a responsive and knowledgeable community of hundreds
of developers and technical users who are located around the world. When you join the community, you will be connected to this group of people who
can help you learn about SDR and respond to your technical and specific questions. Often your question can be answered quickly on the mailing lists.
Each mailing list also provides an archive of all past conversations and discussions going back many years. Your question or problem may have already
been addressed before, and a relevant or helpful solution may already exist in the archive.
