NBB-115 & NBB-230: Network Boot Bars - User's Guide
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.
