2.11. Additional Button Functions The Default and Reset buttons on the NPS front panel can be used to perform the functions described below: Notes: • All Front Panel Button functions can also be disabled via the System Parameters menu, as described in the WTI Firmware Guide. • When the NPS is reset to factory defaults, all user-defined configuration parameters will be cleared, and the default “super” user account will also be restored. Reboot Operating System: Press and hold the Reset button for five seconds, and then release it.
Although communication via Telnet, HTTP and/or HTTPS can be enabled as described in the WTI Firmware Guide, during this bench test procedure, the NPS will be controlled via the Command Line Interface (CLI) using a local PC, connected to either the Serial SetUp Port or Network Port: • Serial SetUp Port: Use the Ethernet Cable and Adapter supplied with the NPS.
Getting Started 3.3. Communicating with the NPS Notes: • Default serial port parameters are set as follows: 9600 bps, RTS/CTS Handshaking, 8 Data Bits, One Stop Bit, No Parity. Although these parameters can be easily redefined, for this bench test procedure, it is recommended to configure your communications program to accept the default parameters. • The NPS features a default IP Address (192.168.168.168) and a default Subnet Mask (255.255.255.0.) This allows network IPv4 access to the Command Line Interface, providing that you are contacting the NPS from a node on the same subnet. Access the User Interface: Start your communications program, (e.g., Tera Term, PuTTy, etc.,) then press [Enter]. Username / Password Prompt: A message will be displayed, which prompts you to enter your username (Login) and password.
