4 Enter your password as requested (the default is “1234”).

5 Enter “bin” to set transfer mode to binary.

6 Use “put” to transfer files from the computer to the Prestige, for example, “put 

firmware.bin ras” transfers the firmware on your computer (firmware.bin) to the Prestige 
and renames it “ras”. Similarly, “put config.rom rom-0” transfers the configuration file 
on your computer (config.rom) to the Prestige and renames it “rom-0”. Likewise “get 
rom-0 config.rom” transfers the configuration file on the Prestige to your computer and 
renames it “config.rom.” See earlier in this chapter for more information on filename 
conventions.

7 Enter “quit” to exit the ftp prompt.

The Prestige automatically restarts after a successful file 

upload

More commands (found in GUI-based FTP clients) are listed earlier in this chapter.

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.

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.

2 Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System 

Maintenance.
