Module Rescue
In the event that it becomes necessary to revert the MVI56E-LDM module back
to its initial out-of-the-box state, there are a number of methods you can use
depending on the condition of the module.
The Rescue process re-installs all of the Operation System commands and
configurations to their original defaults. The files deleted during the rescue
process are the startup scripts in the /etc/init.d path since extra scripts in this
path are automatically executed by the operating system on startup and may
cause problems. All other files may be overwritten to the initial state of the
device. Extra files are not deleted.
If the web pages and services for the module have been altered, it may not be
possible to use the web-based rescue.
Prep and Establish Communications
Place the onboard setup jumper to the installed state.
Ethernet Communication
If the IP address is known, change the network mask and IP of a connected PC
to something compatible.
For example, if the MVI56E-LDM is configured with the default IP address
(192.168.1.250) and network mask (255.255.255.0), the the PC should have the
same IP4 network mask and an IP address in the 192.168.1.xxx subnet.
Note that IP addresses must be unique on the network. If in doubt, create a
physical network consisting of only the MVI56E-LDM and the PC.
Serial Communication
If the IP address if the MVI56E-LDM module is unknown, communication may be
established through the serial configuration port (i.e., Port 1 (upper port)). Use
Telnet or a similar terminal program to communicate with the module. Default
baud is 115,200, 8 data bits,1 stop bit, No Parity, xon/xoff flow control.
