Firmware and Configuration Maintenance 

More commands (found in third party FTP clients), are listed earlier in this chapter. 

Refer to the TFTP and FTP over WAN Will Not Work When section to read about configurations that 
disallow TFTP and FTP to work over WAN. 

The Prestige also supports the uploading of firmware files using TFTP (Trivial File Transfer Protocol) over 
LAN. Although TFTP should work over WAN as well, it is not recommended. 

To use TFTP, your computer must have both telnet and TFTP clients. To transfer the firmware and the 
configuration file, follow the procedure shown next. 

Step 1.  Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not have 

any security checks, 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 the command “sys stdio 0” to disable the console timeout, so the TFTP transfer will not be 

interrupted. Enter “command sys stdio 5” to restore the five-minute console timeout (default) 
when the file transfer is complete. 

Step 4.  Launch the TFTP client on your computer and connect to the Prestige. Set the transfer mode to 

binary before starting data transfer.
