6. Redundancy with NX3030 CPU
305
Half-Clusters Configuration
The Wizard is always used to generate the first version of a redundant project. This guarantees the
initial version is generated quick and correctly.
However, it’s possible that some modifications are necessary in a half-cluster, such as the insertion of
new NX5001 and NX5000 modules that can be executed changing the half-cluster configuration
screen. The following chapters present how to insert and configure the modules NX5000, NX5001
and NX4010.
Some rules and precautions must be followed for a redundant project, as described in the following
sub-sections.
Fixed Configuration in the 0 to 5 Rack Positions
In the 0 to 5 positions of the selected rack, the following modules must be always installed:
ï‚· Power supply NX8000 (positions 0 and 1)
ï‚· NX3030 CPU (positions 2 and 3)
ï‚· NX4010 module (positions 4 and 5)
These modules must not be removed from the original project generated by the Wizard.
Any different configuration in these positions results in an error displayed by MasterTool at the
project compilation.
Ethernet Ports Configuration in the CPU NX3030 (NET 1 and NET 2)
IP Address Configuration
Figure 6-20 presents the CPU NX3030 NET 1 port configuration (the screen for NET 2 port
configuration has a subgroup of these parameters). In order to open this screen, a double click must
be executed on NET 1 or NET 2, below the CPU NX3030 in the device tree.
Figure 6-20. Ethernet NET 1 port parameters
Next the basic parameters of the NET 1 and NET 2 interfaces must be edited. The address has to be
set according to the IP Active Change method, as described in Active IP.
ATTENTION:
The NET 1 and NET 2 interfaces IP addresses, as the Gateway Address, must belong to the same
subnet.
