1 Use telnet from your computer to connect to the P-660H-T1v3s and log in.
Because TFTP does not have any security checks, the P-660H-T1v3s records the IP
address of the telnet client and accepts TFTP requests only from this address.
2 Enter command “sys stdio 0” to disable the management idle timeout, so the
TFTP transfer will not be interrupted. Enter command “sys stdio 5” to restore
the five-minute management idle timeout (default) when the file transfer is
complete.
3 Launch the TFTP client on your computer and connect to the P-660H-T1v3s. Set
the transfer mode to binary before starting data transfer.
4 Use the TFTP client (see the example below) to transfer files between the P-660H-
T1v3s and the computer. The file name for the configuration file is “rom-0” (rom-
zero, not capital o).
Note that the telnet connection must be active before and during the TFTP
transfer. For details on TFTP commands (see following example), please consult
the documentation of your TFTP client program. For UNIX, use “get” to transfer
from the P-660H-T1v3s to the computer and “binary” to set binary transfer mode.
TFTP Command Configuration Backup Example
The following is an example TFTP command:
tftp [-i] host get rom-0 config.rom
where “i” specifies binary image transfer mode (use this mode when transferring
binary files), “host” is the P-660H-T1v3s IP address, “get” transfers the file
source on the P-660H-T1v3s (rom-0, name of the configuration file on the P-660H-
T1v3s) to the file destination on the computer and renames it config.rom.
