Backing up the Summit WM Controller WM200/2000 system configuration:
You can backup the Summit WM Controller WM200/2000 system configuration. You can also define the
automatic schedule backups to occur. While defining a scheduled backup, you can configure to have the
backup copied to an FTP server. The backup will be copied to the FTP server after the backup is
completed on the local drive. For more information, see the Summit WM User Guide.
WARNING!
Whenever you change the system configuration, you must always define the automatic scheduled backup to be
copied to the FTP server. Otherwise, you may not be able to retrieve the system configuration in the event of an
HME card failure.

WARNING!
You should avoid operating the Summit WM Controller WM20 in a LAN in which the DC voltage is overlaid on the
data lines because the LAN may have switches that connect directly without checking the supply voltage. Depending
upon the transformer at the LAN interface, voltages of up to 500 Volts can be induced. Such peak voltages can
destroy the physical LAN controller's logic.
