Utilities/Upgrade Menu

Write security: 2; Read security: 3

The Express XL/XLT’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 XL/XLT starts a TFTP client function which gets the upgrade code from the TFTP server. Se- lecting 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.
