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.
14.6.4 Boot module commands
Prestige boot module commands are shown below. For ATBAx, x denotes the number preceeding
the colon to give the baud rate following the colon in the list of numbers that follows; e.g.
ATBA3 will give a baud of 9.6 kbps. ATSE displays the seed that is used to generate a
password to turn on the debug flag in the firmware. The ATSH command shows product related
information such as boot module version, vendor name, product model, RAS code revision, ISDN
code revision, etc.
