Internal Network - Hitachi COMPUTE BLADE 500 SERIES Management Module Setup Manual

• The MAINT port is for customer engineers for maintenance purposes. You
cannot use this port. Do not connect the cable to the MAINT port,
otherwise the maintenance may not be performed properly.
• The ports of standby management module are usually closed. These ports
become active when the management module failure occurred or the Link
Fault Tolerance switched.

Internal network

Apart from the management network, the system unit has an internal
network. The internal network is used for the following purposes.
• Control communication between the management modules.
• Control communication between the management module and server
blades.
• Control communication between the management module and switch
modules.
The system unit uses the 24bit mask network (subnet mask: 255.255.255.0).
The system unit is configured with 192.168.253.0/255.255.255.0 for the
factory default setting. The IP address, which is used in the internal network,
cannot be used out of the system unit. You must change the IP address and
subnet mask of the internal network when you want to use the IP address,
which specified 192.168.253.0/255.255.255.0, for other than the system
unit.
Note:
• The management module is restarted after changing the internal network
settings.
• Do not change the internal network settings while operating server
blades. If changing the internal network settings during server blades are
in operation, the management module is restarted. The failure event may
not be detected while rebooting.
Tip: When the IP address of network, which specified
192.168.253.0/255.255.255.0, is not used out of the system unit, you do not
need to change the internal network configuration.
The following table describes the internal network.
