How can I use TFTP to load firmware (*.rom) and web pages (*.cob) into CoBos device servers?

---

To load new firmware from a computer:

Enter the following from a TFTP command line interface:
tftp –i <ip address> put <local filename> <destination file name>

The following examples below demonstrate the TFTP command sequence to download the .rom file and the .cob file for XPorts.

For XPort-05:
tftp –i 192.168.1.111 put xpt05_6902.rom X9
tftp –i 192.168.1.111 put xpt_webm_2002.cob WEB1

For XPort-03 and XPort-04:
tftp –i 192.168.1.111 put xpt_6100.rom X5
tftp –i 192.168.1.111 put xpt_webm_1300.cob WEB1

You can load web pages into different web partitions by changing the partition number. E.g. to load a *.cob file into the 4th web partition use the command:
tftp –i 192.168.1.111 put xpt_webm_1300.cob WEB4

Note that not all versions of Windows have the tftp client installed by default. You can enable the tftp client from the Programs and Features Control Panel:

1. Click on "Turn Windows features on or off" near the upper left corner of the control panel window

2. Click the check box next to TFTP Client so it is checked

3. While you're there, also check Telnet Client so it is enabled. You need the telnet client to open a connection to Setup Mode on port 9999

4. Click OK
