IP addresses of the LAN ports are not assigned to each CM. These IP addresses are assigned to the role of master
or slave. If the Master CM is switched, the same IP addresses are reused. Therefore, even if the Master CM is
switched and the physical port is changed, access can be maintained via the same IP addresses. The MAC ad-
dress is not inherited.

When the Master CM is
switched, the IP addresses of
the previous Master CM are
taken over by the new
Master CM.
•
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.
