To verify that the PC-to-unit FTP file transfer was successful, find the current firmware information
via the front panel, or the HTTP or Serial interface (see Sections 5.2.3.2, 5.2.3.3, or 5.2.3.4).
The base modem is now operating with its latest firmware. The firmware update process is
now complete.
Firmware Update
The process sequences through several blocks – this may take several minutes for the
transfer to occur. The modem front panel reports the status as follows:
Programming flash sector #xx
Please wait...
If you stop the transfer before the "PROGRAMMING FLASH SECTOR#xx
PLEASE WAIT" messaging sequence is complete, this could lead to an
incomplete download, and you must repeat the "put" command (Step
2e).
You must make sure to update both images with the same firmware
version for the unit to function properly.
The update from an earlier version to FW Ver. 1.4.8B is a one-way update
path. Once you complete an update to FW Ver. 1.4.8B or later, it is no
longer possible to revert to earlier versions. If you attempt to update to
an earlier firmware version, the modem will detect and disallow this as a
protective measure. The unit will also disallow an attempt to switch to an
image that contains an earlier version of firmware.
f. Wait for the file transfer to end.
If you receive the "Connection closed by remote host" message, wait anothe
minute before continuing. The modem update sometimes takes longer than
FTP client allows.
g. Type "bye" to close the FTP session.
h. Close the Command-line window.
