1. TFTP PUT from this host
Use this method if you have TCP/IP already installed on your PC. BRAdmin32 will use
the TFTP protocol to send the new firmware data to the print server.
2. TFTP GET from a server
If you have a TFTP server installed in your network (many Unix systems provide TFTP
support), you may wish to use this option. The new firmware file must be located in the
TFTP BOOT directory on your TFTP server. In this case, your PC makes the print server
read the firmware data from the assigned TFTP server. If you do not provide the correct
file name, then the upgrade will fail. You must also ensure that the firmware file is set so
that the print server can read the file. On Unix systems you can use the chmod command to
specify file attributes. For example, chmod filename 666 allows the filename to be
accessed by anyone. Also make sure that the TFTP service is running on your Unix server.
