Flash Files
The Switch Module and Remote Module contain a flash file system to store basic
configuration files, the actual firmware and the instructions necessary for starting the
units. The flash memory system retains stored data even with no external power applied.
Access to the flash file system is gained using a PC (FTP or Telnet access via LAN). FTP
must be enabled, if that is the method you are using, and an administrator’s password
should be configured, to control access.
Firmware images stored in the flash file system are saved with extension “.mab.” These
files use binary format.
Configuration files stored in the flash file system are saved with “.swt” extensions for the
Switch Module and “.rem” extensions for Remote Module. All changes you make to the
configuration must be saved to the flash file to be applied. The MC prompts you to save
changes when necessary.
Call Back files stored in the flash file system are saved with the “.cbk” extension. They
contain specific information for the Switch Module and Remote Module boot process (IP
addressing, active configuration file, firmware for boot). The Switch Module saves “.cbk”
files to allow it to contact remote users that are currently disconnected. This file is also
used for Remote Module Login capabilities.
Configuration File Management
Changing the Active Configuration File
When the Switch Module or Remote Module is powered-up, the flash file system loads a
configuration file – “.rem” (Remote Module) or “.swt” (Switch Module) – which contains all
parameters necessary for operation. You may change this “.rem” or “.swt” file so that a
different set of parameters loads.
The default configuration file shipped with the units is “runtime.rem” or “runtime.swt.” To
change this go to Gateway (Remote) ->Utilities->Upgrade->Config File. Select an existing
“.rem” (Remote) or “.swt” (Gateway) file from the list displayed. The display reads
“Change Configuration file to …..” Enter [Y]es or [N]o. Assuming you type “[Y]es” to
change the configuration file, you are prompted to reboot.
This change will not take effect without a reboot. All changes made to the Switch Module
or Remote Module parameters will be saved to the file you selected.
