Utilities/Upgrade Menu
Write security: 2; Read security: 3
The Express L768/L1.5’s firmware can be upgraded using this menu.
Upgrade/Transfer Method
The two methods for upgrading are TFTP and XMODEM. TFTP requires a
TFTP server running somewhere on the network. The Express L768/L1.5
starts a TFTP client function which gets the upgrade code from the TFTP serv-
er. Selecting XMODEM will load the upgrade code through the maintenance
port using any PC terminal emulator with xmodem capability.
Upgrade/TFTP Host
This is required when the transfer method is TFTP. It is the IP address or do-
main name (if DNS is configured) of the TFTP server.
Upgrade/Filename
This is required when the transfer method is TFTP. It is the case-sensitive file
name which is the upgrade code.
Upgrade/Status
This appears when TFTP is used. It displays the status of the transfer as it hap-
pens. Any error or success message will be displayed here.
