10. Firmware Upgrades
Obtaining Firmware
You can obtain the most up-to-date firmware and release notes for the unit from the Lantronix
web site (
www.lantronix.com/support/downloads) or by using anonymous FTP
(
ftp.lantronix.com/pub).
Reloading Firmware
There are several ways to update the unit's internal operational code (*.ROM): using
DeviceInstaller (the preferred way), using TFTP, or using the serial port. You can also update
the unit's internal Web interface (*.COB) using TFTP or DeviceInstaller.
Here are typical names for those files. Check the Lantronix web site for the latest versions
and release notes.

Using TFTP: Graphical User Interface
To download new firmware from a computer:

operational code and *.COB to upgrade its internal web interface).
Note: TFTP requires the .rom (binary) version of the unit's internal operational code.
2. In the TFTP server field, enter the IP address of the unit being upgraded.
3. Select Upload operation and Binary format.
4. Enter the full path of the firmware file in the Local file name field.
5. In the Remote file name field, enter the current internal operational code or WEB1 to
W
EB6 for the internal web interface.
