Figure 1.2 Lan Control (When The Ip Address Of The Slave Cm Is Set) - Fujitsu ETERNUS DX80 S2 User's Manual & Installation Instructions

Chapter 1 Preparation
1.1 Connection Preparation
• 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 Disk storage system.
The IP address of the Slave CM does not need to be set for normal operation.

1.1.2.2 Preparation for Connection to the LAN for Operation Management
The IP addresses and the network devices that must be prepared before an ETERNUS DX Disk storage system is
connected to the LAN for operation management are explained for the following examples of connection
configurations.
Check the network environment and prepare the necessary items.
• IP addresses for the ETERNUS DX Disk storage system
MNT ports are used for connecting a LAN for operation management.
The remote support uses MNT ports for a network connection by default. In this situation, the network
connection for the remote support is transferred via the company LAN. When the network connection for
the remote support needs to be separated from the company LAN, use the RMT ports to connect to the
remote support center via a different network.
• Do not use the RMT port for an operation management LAN. Use the RMT port only for maintenance
work or remote support.
• When an RMT port is used, make sure the IP address of the RMT port is in a different subnet from the
IP address of the MNT port. When network settings are not performed for the RMT port, the RMT port is
disabled.
Make sure to connect each controller to the network for remote support.
• When specifying the IP address of the Slave CM, specify an IP address that is in the same subnet but is
different from the IP address of the Master CM.
• Either or both an IPv4 address and an IPv6 address can be specified for the MNT port and the RMT
port.
