Reloading from a UNIX Host Computer using TFTP
To download the print server firmware from a UNIX host using tftp, first copy the load file
e.g.
Firmname.bin to that host. Make sure that tftp is started by checking the appropriate
files on your system (generally speaking, tftp must be enabled in your /etc/services file
and possibly in another configuration file, such as /etc/inetd.conf ). Refer to your
UNIX system documentation or man pages for additional information.
Now log into the print server remote console using, and execute the following commands:
SET LOAD IP unixhost-ipaddress
SET LOAD SOFTWARE "firmware.bin"
SET LOAD ENABLE
EXIT
where unixhost-ip address is the IP address of the UNIX load host and pathname is the full
path name for the
Firmname.bin file (e.g., /tftpboot/Firmname.bin ). Note that
some tftp implementations require that the load file be located in the /tftpboot directory.
Be sure to put the path name in quotes and remember that UNIX names are case-sensitive.
Also, make sure that your file protection allows general access to the boot directory.
To do this 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.
When you type a CTRL-D or EXIT to exit the remote console, the file Firmname.bin will
then be loaded into the print server. The Data LED on the printer front panel will blink during
the load process and will go out when the process is complete.
If the Data LED does not stop blinking after about two minutes, or start to blink periodically,
check to make sure that you correctly entered all parameters and that your network
connections are good. Then power the print server/printer off and then on again, enter the
SET LOAD ENABLE command, and then type EXIT to exit the remote console and retry the
download.
