Fujitsu ETERNUS DX100 S3 - LAN Control (Master CM;Slave CM); Figure 98 Connection Example When the IP Address of the Slave CM Is Set (and a Dedicated Remote Support Port Is Used)

The following figure provides connection examples and explains the necessary preparation for
when the IP address of the Slave CM is set.
For the ETERNUS DX
, three IP addresses are required (two IP addresses for the MNT ports and
one IP address for the RMT port).

LAN Control (Master CM/Slave CM)
This section explains how the LAN control controller of the ETERNUS DX operates.
When an ETERNUS DX has two controllers, the controller (CM) that is given the authority to man-
age 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.
