CHAPTER 3 Work before Operating System Installation 3.3 Connection and Setting of MMB

FIGURE 3.3 Network Configuration and IP Address of Management LAN

Ports for managing MMB#0 and MMB#1 are connected to the external switching hub device using a LAN cable. At the same time MMB console PC is also connected to the external switching hub device. Physical IP address and Virtual IP address of MMB#0 and MMB#1 are set in identical subnet.

-Physical IP Address (In the above figure, MMB#0=192.168.1.100, MMB#1=192.168.1.101)

-Virtual IP Address (In the above figure, 192.168.1.102)

For external connection (Web browser, Terminal for Maintenance, REMCS, etc.), communication is done by virtual IP address.

Service Installation Manual (C122-E180EN).

Remark

-Packets are transmitted from MMB in “NTP”, “Alarm E-Mail”, and “REMCS”. When both the physical IP address and the virtual IP address of MMB are set, the transmission source IP address of packet is considered as the physical IP address of the MMB.
