Download the UpdateIP utility software if you are updating the existing firmware in your product. The utility file is in .zip format.
Another method is to use the TFTP command from the Command Line prompt (ie: Start>Run> then type "cmd")
You can upgrade the device from 2000/XP without resetting any of the previous setting changes. Just make sure that the 2000/XP workstation can ping to the IP address of the the print server. From there, just access the workstation’s Command (DOS) prompt and enter this command:
(if the firmware file was saved in the C:\temp directory)
C:\Temp>tftp –i [IP address of device] put [firmware file] access
Example: C:\Temp>tftp –i 172.16.3.45 put wpss399.bin access
