LAN Connection
Note
• Each CM has an LED that lights up green to identify when it is the Master CM.
• Setting the IP address of the Slave CM ensures that ETERNUS Web GUI or ETERNUS CLI can be used from
the Slave CM if an error occurs on the LAN path for the Master CM.
The Master CM and the Slave CM perform different functions. The Slave CM can only switch the Master
CM and display the status of the ETERNUS DX.
The IP address of the Slave CM does not need to be set for normal operation.
