Step 1.
Use telnet from your workstation to connect to the Prestige and log in. Because TFTP does not
have any security check, the Prestige records the IP address of the telnet client and accepts TFTP
requests only from this address.
Step 2.
Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.
Step 3. Enter command "sys stdio 0" to disable SMT timeout, so the TFTP transfer will not be
interrupted.
Step 4.
Launch TFTP client on your workstation and connect to the Prestige. Set the transfer mode to
binary before starting data transfer.
Step 5.
Use the TFTP client to transfer files between the Prestige and the workstation. The file name for
the firmware is "ras" and for the configuration file, "rom-0" (rom-zero, not capital o).
If you upload the firmware to the Prestige, it will reboot automatically when the file transfer is completed.
Note that the telnet connection must be active and the SMT in CI mode before and during the TFTP transfer.
For details on TFTP commands, please consult the documentation of your TFTP client program. For UNIX,
use "get" to transfer from the Prestige to the workstation, "put" the other way around, and "binary" to
set binary transfer mode.
