LAN Control (Master CM/Slave CM)

This section explains how the LAN control controller of the ETERNUS DX operates.
For the two controllers in the ETERNUS DX, the controller (CM) that is given the authority to manage the LAN is
called the Master CM and the other CM is called the Slave CM.
When an error occurs in the Master CM or LAN, the Master CM is switched automatically.
