4. Set your communication program for ASCII Mode, then use the
program’s "Send File" function to transfer the upgrade file to the NBB.
Select ASCII format, then specify the filename and directory location
where the firmware upgrade file resides.
5. If the upload is successful, the NBB will load the upgrade firmware into
memory, and then reboot itself.
Note: If you are performing the upgrade procedure via the
Network Port, the NBB will break the network connection when
the system is reinitialized. However, the NBB will retain the
current settings for the IP Address, the Telnet Port Number, Web
Server Port Number and Console Port Mode and Baud Rate.
6. Incomplete Upload: If the upload is interrupted, times-out, or if the
update file becomes corrupted during transfer, the NBB will display a
screen which asks for confirmation before proceeding. To proceed, type
1 and press [Enter], then return to Step 4 above to retry the upload, or
press [Esc] to reboot the NBB unit.
7. Recovery Mode: In the rare event that the NBB operating system
becomes corrupted during installation, front panel indicators will blink,
and the unit will automatically switch to Recovery Mode. If the unit
switches to Recovery Mode, first access the NBB command mode to
reset the Console Port to 9600 bps, Eight Data Bits, No Parity, One Stop
Bit, and then return to step 3 above and repeat the upload procedure.
When firmware upgrades are available, WTI will provide the necessary files
via download or mailed CDROM. At that time, an updated Users Guide or
addendum will also be available.
