Using TFTP: Command Line Interface
To download new firmware from a computer:
1. Enter the following from a TFTP command line interface:
tftp –i <ip address> put <local filename> <destination file name>
The following examples demonstrate the TFTP command sequence to download the
.ROM file and the .COB file:
tftp –i 192.168.1.111 put xdrpl_6100.rom R1
tftp –i 192.168.1.111 put xdrpl_webm_1402.cob WEB4
2. In the Remote file name field, enter the current internal operational code (R1) or
WEB1 to WEB19 for the internal web interface.
Recovering the Firmware Using the Serial Port and
DeviceInstaller
If for some reason the firmware is damaged, you can recover the firmware file by using
DeviceInstaller to download the *.ROM file over the serial port.
To recover firmware:
1. Start DeviceInstaller. If your PC has more than one network adapter, a message
displays. Select an adapter and click OK.
2. From the Tools menu, select Advanced/Recover Firmware. The Serial Port
Firmware Upgrade window displays.
3. For Port on PC, enter the COM port on the PC that is connected to the serial port of
the Lantronix unit.
